I was just about to turn off the lights and go to sleep when I saw this in my notifications. Heck, I can sleep anytime. So excited to see another plastic pinion for the hour counter on the bottom of the mainspring barrel. Definitely worth it. Omega or not, this video is going into my ETA 775x folder. Thank you for sharing.
Hi guys, note that at 40:55 I say that the heart cam is "at its flattest" when the chronograph seconds hand is at 30 seconds. Not sure why I chose those words, but the reason we test at 30 seconds (ideally it would be at 6 hours, 15 minutes and 30 seconds so all cams were in the same position) is that at that time, the hammer will hit the sharpest point of the heart cam. If there is an issue with the cam or the hammer, this is the point where you are most likely to see those issues. The chronograph seconds hand is much more likely to have these issues than the minute and hour counters, so we are in general good with only checking that hand like this.
I just sent my mk40 with the day/night sub dial for service. It’s a funky dial and i love it. This watch is my daily and the complications are perfect for a dunce like me who can never remember what day it is 🤣 It has been running like a champ but recently it just stopped running. Gave it the bump and it would get going but eventually stop again. Anyway, great video 👍🏼
Assembling a multi drawer 'Ikea' type wardrobe is a drop in the hat compared to the many parts on this timepiece with no instructions. Have to hand it to your expertise and skill. Watch making and service is an Amazing art. Always fascinated by the skill of the makers and parts involve. Kudos to you..!!
Thanks for the video, I have the black dial and I’m still in love after two years. It’s such a fun watch to own and look at, I just wish it had 20mm lugs
Thanks for watching and for your comment, Andrew! The black dial version is a beautiful watch indeed and the size is just right for a wide swatch of buyers. If you want 20mm lugs you should start looking at the Professional though 😉
Another outstanding video! I absolutely love Switzerland. Been to Basel and Zurich a number of times for work. Got to visit my mothers family in Rastatt while there a few times as well (including my aunt 😎). I was always amazed at how many languages many Swiss people speak….German, French, Italian and English. Maybe that is why you folks are such good watch makers….plenty of brain power!
Thanks for sharing that! Switzerland is indeed a very nice country and it's kind of crazy all the languages spoken here. I'm actually Norwegian myself, but feel quite at home here :)
A huge thank you for posting this video. I'm looking at purchasing this model watch as a present to myself for reaching 30 years at my place of employment. Have a couple of Omegas and really love the look and style of them. Though I do love the black dial 3520.50 version. Love the 7750 family of movements. Absolute joy watching (Binging really) the videos on your channel and the humour is brilliant hahaha. Huge G'day from Australia!
I have several watches in my collection that are far more valuable monetarily, but this one is the one I come back to for wearing again and again. I find it quite handsome, reliable and with useful functions. My "moon watch," on the other hand, seldom gets worn.
It is a shame I chose one of these 7750 movements (3330 in my case) for my second luxury watch I have purchased. Although I have the funds to purchase more, I am so very satisfied with this. It's heavy, rather loud, functional, reliable, and looks handsome.
I have the Omega speed master racing M. Schumacher 2002 champion version. I guess is of the same movement. Love it. Thanks for your effort in this video for me to understand more how complicated the movement is.
Hello B T, thanks for watching! Your Schumacher racing version is probably using a module such as the one in this video: ua-cam.com/video/MCSx7FvdPjY/v-deo.html That's an even more complicated version 😉
Thanks, Kamlapati! She turned five in the meantime and was very happy with her unicorn birthday party 🦄😂 She speaks English and French with a little Mandarin and Dutch thrown in for good measure :)
Vintage Watch has become a must watch (excuse the pun) every day. Forget my daily supplements it does me much more good. Cures most ills. All the best. Mick.🇬🇧
Awesome video, as usual and funny banter as well!! I’ve been looking at these vintage Speedmasters, and now I know enough to make a better decision on what model.
Thanks a lot! I don't really do servicing jobs, the watches on the channel are pretty much exclusively watches I have bought and are going to re-sell. I might have a recommendation for you for servicing, depending on where you are located?
@Vintage Watch Services thank you for your reply. The quality of your work, you should start. I even enjoyed the humour. I am in Scotland and was going to send it to Omega, but they do seem a bit step for this type of movement. Thank you and keep safe👍
My wife got me a very similar watch to this one from Longines (the “Master Complications”) when we got engaged. Honestly, it looks to me like the biggest differences between them are a different handset and the presence of the moon phase indicator on my Longines.
Hi Tiger, yes, your watch likely has the L687 movement, which is based on the 7751. It has a column wheel instead of the cam, making it a bit more special, but is otherwise very similar. I think a lot of people would say your Longines is better value than this Omega 😉
@@VintageWatchServices I actually think mine is cam based, not column wheel. It’s an older one, dating back to 2013. Just checked it. It’s got an L678.2.
Have this one in black, the 3220.50, and I really like it, among my Planet Ocean 8500 and Seamaster 8800. This original of this watch, the 3520.50, made me really want mechanical watches.Really nice and sobering video! Just a question - why you didn't clean/polish the hands/arrows, or is it you then you need to replace them completely with brand new ones?
I have this model and a 321 movement Speedmaster bought in 1967. I believe the movements are completely different. Love to see the difference. They’ve both been recently serviced at a cost of much more then the original price. By the way, Great video!
Hello Mac, yes, the 321 is radically different from this one. The 321 is a manual winding Lemania movement, while this one has an automatic Valjoux 7751. The 321 is considered the superior movement, and is of course the movement used in the Professional version, aka the Moon watch. So your Moon watch is probably worth 3-4 times more than your automatic :)
I like 👍 the sophisticated look 👀 of this watch. It looks like 👍 an airplane ✈️ dashboard. It’s even automatic. Again, exercise great 😊 care, without getting magnets 🧲 by your watch. I see Omega is the name. I wouldn’t be surprised 😲 that this watch could run 🏃♀️ for $3500.00 new, but I could be wrong 😑. Your friend, Jeff.
@@VintageWatchServices Exactly! When I find out that some watch that I like does not have that feature it really disappoints me. Crazy, but what can you do. 😁😁
Revisiting this video and reading the comments, I cannot feel but let down by Omega. The movement of this watch - despite some of the decorations - looks extremely cheaply made; all the press cut gears, springs and bridges in particular. Also the hands and dial lack class. Maybe I am just too old and still too enthralled by those older, copper-plated movements with beautiful dials they used to make. The only values that deserve highest highest praise here are - as always - your expertise, comments and the quality of your video.
1. This watch is a beauty beauty beauty. 2. I never understood how anybody in their right mind could use a snap on / pressed caseback. There are so many elegant ways of doing case backs. Screw down or screw-in are two of the best. It breaks my heart (and my eyes to be honest) when even watch makers have to poke the case open with some metal blade applying all kinds of forces, shaking etc...
Looks like there's as many chronograph parts as a Seiko has on the dial side. Also, you have gone through quite the number of changes this year, but your videos have gotten even better. I hope you can kind of make a long term home and settle down a bit.
Hello Clay, thanks so much for that! When moving into my new house I told the guys who helped me move that I want to die in this house, and I hope that comes true. Not necessarily in the short term though 😂 I'm planning a few things to make the videos better, and in a month or two I hope to have reached the level I'd like them to be. So stick with me!
very good material and great job. very nice watch, valjoux 775x is very good very accurate it has great tolerances for the service time and the accuracy of this service but they mount it everywhere, for someone who loves what is inside more than outside such omega is not very omega. I know it's a great watch and has many fans. I like 321/861 more (I know it's lemania). these have the right color :) best regards and waiting for more
Thanks so much Karol! I fully agree, and that's why I like vintage Omegas much more than newer ones 😁 The 775xs are certainly very good movements but it's something quite different with a Lemania based Omega!
Hy! That movement is very interesting indeed! Exceptional work you did there! I have a silly question and I really hope you can answer it, I have always wondered how do you know which screw is correct to insert in the movement, visions that are many and of different sizes. Thanks for sharing this video, it's always the master watchmakers who have these skills, most just ship a watch to the factory, yours is a mastery and an art that is slowly being lost, a real shame ... Best regards Jack
Hello Jack, thanks for watching! Your question is not silly whatsoever, it is probably one that absolutely everyone working on watches struggle with. The easiest answer is when you're working on a relatively modern watch, like this one, where you can find the technical communication. In it, all the screws are listed with drawings. For older watches, it comes down to an understanding of what different types of screws are intended for, e.g. a screw with a shoulder has a different purpose to a flat headed screw. And it's always a good idea to put the screw right back in its hole after taking the part off if you are uncertain or if you are working on a complicated watch.
I haven't completed watching the video but I am enjoying it so much. Thank you. I am a watch noob and searched this watch after seeing it on IG. Question: so is it better to get the module or the 7750 movement?
Dizzying array of parts and complexity. I applaud your patience. Glad you were able to edit out the nasty words. I'm surprised that such a meticulously designed and delicate movement does not have a screwdown caseback.
Good question... Could be that someone opened the watch and fiddled around, and if you're not really sure what you're doing or don't have proper testing equipment but the watch seems to run fine, well... I really wouldn't know.
Hi,I really enjoyed this as I own one of these but my one has a screw on back assume as it has the lug recesses for the tool that’s used for removing it.would that make it a more modern version?
Hello Mervyn, thanks for watching! The type of back depends on the specific reference, but newer Speedmaster Automatics indeed come with screw down backs. Screw down backs are in general a better solution for a watch, but it doesn't necessary reflect on the value of it.
Thanks again for a great video. The use of the etachron tool to change the position of the hairspring relative to the index pins was both fascinating and illuminating. Did you use a microscope to see what direction you needed to rotate the stud holder, or was it more trial and error while the balance assembly remained running while watching its performance on the timegrapher?
Hello Daniel, thanks for that! I mostly watch the timegrapher while adjusting the regulator, but I use the microscope to inspect if the hairspring is in the middle of the index pins and to see if the gap is how it should be. You can also look at how the hairspring develops, it should develop more evenly after you adjust the stud carrier.
@@VintageWatchServices Well, again, seeing that aspect of watch repair/restoration was great. As a hobbyist, the balance assembly is the area of greatest trepidation for me. When I acquire a vintage watch to service/restore I hope and pray that the balance assembly functions properly from the outset. While I have replaced hairsprings, adjusted the collet for beat error, and moved index pins, it has typically been while holding my breath in the hope I won't botch it. That adjustment you made on the stud holder brought it all to a new level for me. Thanks for the reply.
I had wondered about using lino or vinyl on the floor instead of carpet. I used to work in a telephone exchange, and the floor had lino on it. From time to time I did drop a small screw or such like, and if it landed on the floor then, if you got down close to the floor, you could see that part. I don't know how I'd have gotten on looking for one of those small springs if it landed on the floor, but I think it would be a bit easier than with carpet.
Hello Bram, thanks for watching and it's great that you want to start working on watches :) There are quite a few videos out there on the basic tools needed, for instance this one: ua-cam.com/video/2tAMDxMqqy8/v-deo.html Best of luck!
May I ask what liquids do you have in the cleaning machine? first jar? what fluid what proportion? and do you use it for all kinds of mechanisms? different mechanisms different metal? what about the second? distilled water ? third isopropyl alcohol? will you reveal secrets? :)
Hello Karol, thanks for your question! I'm a simple guy and haven't really seen a lot of differences between different fluids. So I've resorted to a simple setup: Elma WF Pro cleaning fluid in the first two jars and Elma Suprol Pro in the last two. For the ultrasonic cleaning of the case I however use four or five different fluids, depending on the metal of the case.
Hello, thanks for watching! Most of the time you can use a generic movement holder, but when you're placing the hands it's very convenient to have a special 7750 holder with built-in pushers.
Hello Matt, somehow your comment was blocked by the UA-cam algorithm... You can find them for from around €1500 up, the lower the price the lesser condition.
Thanks for another interesting and informative episode where I learned that not all Speedmaster Reduced watches have ETA 2892's with a Dubois Depraz module but, indeed, some have ETA 7750's! That's a nice looking watch that you have there by the way. I've heard that some watchmakers (including Omega itself) don't like servicing the DP modules and simply replace the whole assembly instead of servicing it . I was wondering if you had any thoughts on the matter? Looking forward to your next offering.....possibly something with Val 72 cal under the hood coming up. Thanks.
Thanks Randy! Most of the 90's Speedie Automatics have 775x movements, but perhaps most notably the Schumacher ones have the DD module. The DD module is finicky at best, with a lot of floating parts. I hope to get my hands on one soon to make a special horror show episode 😬
@@VintageWatchServices Thanks for that, all I know is what I see on WatchBox reviews, and it's all Schumachers, that's why your channel is so interesting!
Thanks for watching! When you see a Speedmaster with the subdials at 6, 9 and 12, it has a version of the 7750 inside it. Sometimes even with the subdials at 3, 6 and 9 :)
I seems to me that you don't change the mainspring as often as (I think) other watchmakers do. In this case, with a Valjoux 7751, wouldn't that make sense?
Hello Aurelius, if a mainspring still is in good condition you don't need to change it, and you could even argue that it's better not to. The main reason is that a stronger mainspring will lead to more strain on the movement, and thus more wear. And for a vintage watch you'd rather reduce the wear a little bit than improve the timekeeping with a second or two. The other reason is that the correct mainspring may not be easy to find. That's of course not the case for this watch, as you indicate. This said, it's indeed very common for a lot of watchmakers to always put in a new mainspring. It will pretty much guarantee a high amplitude and help make the watch run more accurately as a result.
Nice work....my reduced has an obvious problem: the winding action on the crown is very hard and crunchy as if sand was stuck in the pinions...:(...By the way i've seen some watchmakers oiling the palets of the palet- fork is that necessary? best regards
Hello Art, thanks for watching and for your question! If the winding action is heavy on an automatic watch, it's most often due to issues with the reverser wheel(s). Has it been long since it was serviced? And yes, the pallet stones (typically the exit stone only) need to be oiled. In most of my videos I show that, but I couldn't for the life of me find the snippet of that when publishing this one 😂
@@VintageWatchServices thank you very much for your reply! i bought it 2 years ago with a big internet well-known british dealer so it was supposed to be serviced. In fact i just sent it to omega last month for a regulation (partial service) and they changed the glass, pushers etc ...(which i didn't really care, the new glass is a bit different) and now it is quite hard to wind manually (also on this watch it seems that the gasket hits the winding stem and maybe hinders the winding action) thanks anyway!
@@artblend4278 Then you should absolutely contact them and tell them that you're experiencing these issues. You should also ask them whether the crystal they put on the watch is correct for the reference. Normally they should give you a year warranty after a service so this is on them, from what I can tell.
@@VintageWatchServices hello again....yes i wrote yesterday to omega asking what kind gesture they could do on a future service. Yes the glass is carved with the logo but I think they decided to change very slightly the doming and it now looks more like a saphire...Anyway thanks for your help...have a great week end!
Hello Baqi, thanks for watching and for your interest in the watch! I haven't yet listed it and another viewer actually also said he wants to buy it :) I'll check the price and take some photos. You can mail me at Stian@vintagewatchservices.eu to keep in touch about it
I think I'd be happy with anything that was well-made and historied. But before I can graduate to trying out my hand on a watch that may be of some value for it's time, I'll need to watch out for the next Taylor Swift purchase my wife makes, so I can sneak in a full set of real screwdrivers (not ones I filed from a dollar store eye glass kit), 4 essential oils (lubricants), and oilers. I have no idea what Era I'd be able to get the staking set, crystal press, and whatever other specialty tool you don't need until you need it (nothing else will do). 🎉
Hi, may I ask you a question: My Mark 40 rattles when I tap the glass with my finger. I guess it's the rotor. Is that normal? I can send you a video where you can see/hear the problem. Thank you 🙏
Thanks for watching and for your question! It's a complicated story... Omega has a long and very proud story of manufacturing their own movements before the quartz crisis (although their chronographs used Lemania movements, Lemania being part of the same group of companies). They started using ETA movements during the quartz crisis to save costs, and also as the 10xx family of movements were less than enthusiastically received... They started making in-house again in the mid 2000's, but in reality most of these movements were made by ETA to Omega's specifications. Only in the last few years have they started using true in-house movements again, but ETA still contributes technology and manufacturing, as far as I know. So it's complicated 😄
Hi Mervyn, I honestly don't know and never counted! 😂 I believe there are around 110 parts in the 7750, so probably some 150 or thereabouts in the 7751
I've noticed you like to put the screws back after you remove the part. How do you know they were in the correct spot on a watch that may have been "serviced" before?
Hello Matthew, that's a great question! Sometimes screws can be in the wrong place from the previous service but mostly that would lead to issues. Thus if the watch runs well after the service, it should be fine. For newer watches the technical communication is also easier to find, so you have a reference of in doubt.
Hello Steven, thanks for watching! It's a bit difficult to say what might be wrong without seeing your watch, there could be a lot of reasons. You'd have to have it opened up and looked at.
When it comes to any commodity nowadays. People pay for the brand not quality. Omega is an established brand with lots of history therefore they have built a value. Building value into your product takes years and millions of dollars.
Hello Mohnad, thanks for watching and for your question! 1861 is essentially the 861 with rhodium plating instead of copper. They're both very high grade calibers that are not too difficult to service for experienced watchmakers, but I wouldn't recommend touching them unless you really know what you do.
only thing I cannot grasp is the value under parameters. It shows two values, bph (18000 and up) but also a number of degrees (52 very often (with 18000) or 49 with 28800. What does that number of degrees (what type of degrees?) mean ?
Thanks for watching! The lift angle is the angular rotation of the balance wheel while the impulse pin is in contact with the pallet fork. This value has a direct impact on the amplitude, seeing as the timegrapher calculates the balance wheel's rotation based on the time between the impulse pin hitting the insides of the pallet fork from each direction.
@@VintageWatchServices it’s the same watch as in the video, the numbers are from it sitting face up. No other positions available at this time. It’s one I’m considering buying and was wondering if the numbers indicate it is in need of a service.
@@VintageWatchServices I am wondering if those results show that it is in need of a service or will need one soon, I’ve heard that this model needs services quite often?
@@triumph1974 250 degrees amplitude for a 7750 is low, indeed. Timegrapher readouts aren't really that valuable, as they only show a snapshot at one point in time. Thus you will not know how the watch runs over time, how the power reserve is, positional errors etc. This watch most likely needs a service. And the 7750s don't need servicing more often than other watches, about every five years is the norm.
Hello Kurt, thanks for watching and for your question! It can be a few things, but typically it would either be a result of dirt in the mechanism or incorrect depthing between the clutch pinion and the chronograph wheel. It might also be a problem with the teeth, but that is much less likely. Has it been a long time since the watch was serviced?
@@VintageWatchServices Hi yourself. I got this 7751 back in 2005. It was like that when I bought it. Serviced in 2011, and 2017. Whenever I mention it to my watch guy, he just says don't worry about it.
Well, in a sense he's right, in that no one actually buys a chronograph to measure time 😁 But after a watch is serviced it should work as it was designed to do. If it doesn't, the service isn't complete.
@@VintageWatchServices Makes sense. Don't get me wrong; my guy is pretty good. When he services it again next year, I will share your take on this. My Omegas, and other ETA movements sweep like "glass." Thanks so much. Good luck to you.
A great video of a very complicated watch. And a wonderful rendition of the BeeGees singing the Rose Royce classic Car wash!
Many thanks, Martin! 😂

I have this model and a 321 movement Speedmaster bought in 1967. I believe the movements are completely different. Love to see the difference. They’ve both been recently serviced at a cost of much more then the original price. By the way, Great video!
Hello Mac, yes, the 321 is radically different from this one. The 321 is a manual winding Lemania movement, while this one has an automatic Valjoux 7751. The 321 is considered the superior movement, and is of course the movement used in the Professional version, aka the Moon watch. So your Moon watch is probably worth 3-4 times more than your automatic :)
If you don’t mind my asking what is the service cost on this watch? I’m about to buy one and really would like to know. Thank you
Ich habe noch nie so eine schöne Uhr von Omega gesehen. Ein Prachtstück von Technik.
That's very nice to hear :) It really is a beauty indeed!
I like 👍 the sophisticated look 👀 of this watch. It looks like 👍 an airplane ✈️ dashboard. It’s even automatic. Again, exercise great 😊 care, without getting magnets 🧲 by your watch. I see Omega is the name. I wouldn’t be surprised 😲 that this watch could run 🏃♀️ for $3500.00 new, but I could be wrong 😑. Your friend, Jeff.
This is the next watch I buy.
I just discovered your channel. Excellent video, and great narration!
Great to hear and welcome aboard! More to come, so stay tuned :)
Would have been nice if one could have seen how you are adjusted the hair spring
But as always great video !
It was nice to see how the chronograph minute counter works at 28:01. 👍 Don't know why, that accelerated jump the hand does looks so cool.
Yep, watching those wheels flip over is mesmerizing! Kind of worth it waiting a minute to see that 😂
@@VintageWatchServices Exactly! When I find out that some watch that I like does not have that feature it really disappoints me. Crazy, but what can you do. 😁😁
Revisiting this video and reading the comments, I cannot feel but let down by Omega. The movement of this watch - despite some of the decorations - looks extremely cheaply made; all the press cut gears, springs and bridges in particular. Also the hands and dial lack class.
Maybe I am just too old and still too enthralled by those older, copper-plated movements with beautiful dials they used to make. The only values that deserve highest highest praise here are - as always - your expertise, comments and the quality of your video.
😊👍
1. This watch is a beauty beauty beauty.
2. I never understood how anybody in their right mind could use a snap on / pressed caseback. There are so many elegant ways of doing case backs. Screw down or screw-in are two of the best. It breaks my heart (and my eyes to be honest) when even watch makers have to poke the case open with some metal blade applying all kinds of forces, shaking etc...
Looks like there's as many chronograph parts as a Seiko has on the dial side. Also, you have gone through quite the number of changes this year, but your videos have gotten even better. I hope you can kind of make a long term home and settle down a bit.
Hello Clay, thanks so much for that! When moving into my new house I told the guys who helped me move that I want to die in this house, and I hope that comes true. Not necessarily in the short term though 😂 I'm planning a few things to make the videos better, and in a month or two I hope to have reached the level I'd like them to be. So stick with me!
Splendid job
At least you are “hands” on with this service! Nice job, 775x are finicky to work on.
Thanks Geoff! The 775x are a bit finicky indeed, but I suppose you get used to them :)
You bold enough to work on such complex movement , and btw how much cost for servicing this type of movement ?
Servicing this kind of watch costs about $650
@@VintageWatchServices I expected the cost will be double of that considering how complex is that movement , thanks sir
very good material and great job. very nice watch, valjoux 775x is very good very accurate it has great tolerances for the service time and the accuracy of this service but they mount it everywhere, for someone who loves what is inside more than outside such omega is not very omega. I know it's a great watch and has many fans. I like 321/861 more (I know it's lemania). these have the right color :) best regards and waiting for more
Thanks so much Karol! I fully agree, and that's why I like vintage Omegas much more than newer ones 😁 The 775xs are certainly very good movements but it's something quite different with a Lemania based Omega!
Hy! That movement is very interesting indeed! Exceptional work you did there! I have a silly question and I really hope you can answer it, I have always wondered how do you know which screw is correct to insert in the movement, visions that are many and of different sizes. Thanks for sharing this video, it's always the master watchmakers who have these skills, most just ship a watch to the factory, yours is a mastery and an art that is slowly being lost, a real shame ... Best regards Jack
Hello Jack, thanks for watching! Your question is not silly whatsoever, it is probably one that absolutely everyone working on watches struggle with. The easiest answer is when you're working on a relatively modern watch, like this one, where you can find the technical communication. In it, all the screws are listed with drawings. For older watches, it comes down to an understanding of what different types of screws are intended for, e.g. a screw with a shoulder has a different purpose to a flat headed screw. And it's always a good idea to put the screw right back in its hole after taking the part off if you are uncertain or if you are working on a complicated watch.
@@VintageWatchServices Thanks so much for your time!
With best regards from Switzerland Jack
I haven't completed watching the video but I am enjoying it so much. Thank you. I am a watch noob and searched this watch after seeing it on IG. Question: so is it better to get the module or the 7750 movement?
Hello Hashem, thanks for watching! In general I'd always recommend an integrated movement rather than a module.
@@VintageWatchServices Thank you for your reply and for your videos. I am happy new subscriber. From Saudi Arabia :D
Welcome aboard! :)
Dizzying array of parts and complexity. I applaud your patience. Glad you were able to edit out the nasty words.
I'm surprised that such a meticulously designed and delicate movement does not have a screwdown caseback.
Thanks Frank! Yes, it's a bit strange indeed. It might be to further differentiate it from the Professional version, which has a screw on case back?
@@VintageWatchServices what's the professional version? Is it still triple date with white dial that's professional?
Great video, as always!
At the beginning to checked the accuracy. What was it like after the service and is this movement usually accurate? Neil
Great to see the hairspring adjustment, but how does a watch get so out of whack to begin with?
Good question... Could be that someone opened the watch and fiddled around, and if you're not really sure what you're doing or don't have proper testing equipment but the watch seems to run fine, well... I really wouldn't know.
Thanks for your answer.I have sussed it out,lol.I notice your case back was push on ,mine is screw on.is there a reason why they are different?
Hello Mervyn, no real reason, no, they just did it differently with different references. I believe they are all screw down nowadays.
@@VintageWatchServices thanks for replying👍
Nice work my friend!
Hi,I really enjoyed this as I own one of these but my one has a screw on back assume as it has the lug recesses for the tool that’s used for removing it.would that make it a more modern version?
Hello Mervyn, thanks for watching! The type of back depends on the specific reference, but newer Speedmaster Automatics indeed come with screw down backs. Screw down backs are in general a better solution for a watch, but it doesn't necessary reflect on the value of it.
Thanks again for a great video. The use of the etachron tool to change the position of the hairspring relative to the index pins was both fascinating and illuminating. Did you use a microscope to see what direction you needed to rotate the stud holder, or was it more trial and error while the balance assembly remained running while watching its performance on the timegrapher?
Hello Daniel, thanks for that! I mostly watch the timegrapher while adjusting the regulator, but I use the microscope to inspect if the hairspring is in the middle of the index pins and to see if the gap is how it should be. You can also look at how the hairspring develops, it should develop more evenly after you adjust the stud carrier.
@@VintageWatchServices Well, again, seeing that aspect of watch repair/restoration was great. As a hobbyist, the balance assembly is the area of greatest trepidation for me. When I acquire a vintage watch to service/restore I hope and pray that the balance assembly functions properly from the outset. While I have replaced hairsprings, adjusted the collet for beat error, and moved index pins, it has typically been while holding my breath in the hope I won't botch it. That adjustment you made on the stud holder brought it all to a new level for me. Thanks for the reply.
I had wondered about using lino or vinyl on the floor instead of carpet. I used to work in a telephone exchange, and the floor had lino on it. From time to time I did drop a small screw or such like, and if it landed on the floor then, if you got down close to the floor, you could see that part. I don't know how I'd have gotten on looking for one of those small springs if it landed on the floor, but I think it would be a bit easier than with carpet.
Oh yes, laying carpet in a place where you work with small parts is a very clear signal of a wont for masochism 😉
Dear Watch Maker, I am very much intrigued by your profession. Is is possible you list a set of basic tools and I need to get into this?
Hello Bram, thanks for watching and it's great that you want to start working on watches :) There are quite a few videos out there on the basic tools needed, for instance this one: ua-cam.com/video/2tAMDxMqqy8/v-deo.html
Best of luck!
@@VintageWatchServices thanks!!
May I ask what liquids do you have in the cleaning machine? first jar? what fluid what proportion? and do you use it for all kinds of mechanisms? different mechanisms different metal? what about the second? distilled water ? third isopropyl alcohol? will you reveal secrets? :)
Hello Karol, thanks for your question! I'm a simple guy and haven't really seen a lot of differences between different fluids. So I've resorted to a simple setup: Elma WF Pro cleaning fluid in the first two jars and Elma Suprol Pro in the last two. For the ultrasonic cleaning of the case I however use four or five different fluids, depending on the metal of the case.
@Vintage Watch Services Does one use a generic block/holder to do service on the 7750, or is it a special model?
Hello, thanks for watching! Most of the time you can use a generic movement holder, but when you're placing the hands it's very convenient to have a special 7750 holder with built-in pushers.
@@VintageWatchServices Thank you. I will keep that in mind.
Nice work!
How much would it be to buy this watch if one could be found and another excellent video thank you 👍🏴
Hello Matt, somehow your comment was blocked by the UA-cam algorithm... You can find them for from around €1500 up, the lower the price the lesser condition.
The Seiko "Pouge" has been in space too. :)
Yep!
Insane amount of parts - like building the most complicated horse buggy in the 21st century
It’s surprising that the time Grapher doesn’t have some adjustment for the waveform view.
At 30:31 I was reminded of the Beloved Aunt episode of Curb Your Enthusiasm. In which a typo got Larry David in very deep water.
😂👍
Thanks for another interesting and informative episode where I learned that not all Speedmaster Reduced watches have ETA 2892's with a Dubois Depraz module but, indeed, some have ETA 7750's! That's a nice looking watch that you have there by the way. I've heard that some watchmakers (including Omega itself) don't like servicing the DP modules and simply replace the whole assembly instead of servicing it . I was wondering if you had any thoughts on the matter?
Looking forward to your next offering.....possibly something with Val 72 cal under the hood coming up. Thanks.
Thanks Randy! Most of the 90's Speedie Automatics have 775x movements, but perhaps most notably the Schumacher ones have the DD module. The DD module is finicky at best, with a lot of floating parts. I hope to get my hands on one soon to make a special horror show episode 😬
@@VintageWatchServices Thanks for that, all I know is what I see on WatchBox reviews, and it's all Schumachers, that's why your channel is so interesting!
There is a newer model of this watch with a more silver dial and the GMT subdial has a hand with an arrow at the end. Does that use the same movement?
Thanks for watching! When you see a Speedmaster with the subdials at 6, 9 and 12, it has a version of the 7750 inside it. Sometimes even with the subdials at 3, 6 and 9 :)
Great video, love the Speedy!!!
Thanks for watching Ben and the Speedy is indeed a great watch :)
I seems to me that you don't change the mainspring as often as (I think) other watchmakers do. In this case, with a Valjoux 7751, wouldn't that make sense?
Hello Aurelius, if a mainspring still is in good condition you don't need to change it, and you could even argue that it's better not to. The main reason is that a stronger mainspring will lead to more strain on the movement, and thus more wear. And for a vintage watch you'd rather reduce the wear a little bit than improve the timekeeping with a second or two.
The other reason is that the correct mainspring may not be easy to find. That's of course not the case for this watch, as you indicate.
This said, it's indeed very common for a lot of watchmakers to always put in a new mainspring. It will pretty much guarantee a high amplitude and help make the watch run more accurately as a result.
@@VintageWatchServices Thank you very much for that interesting and detailed answer. I highly appreciate it.
👍
Nice work....my reduced has an obvious problem: the winding action on the crown is very hard and crunchy as if sand was stuck in the pinions...:(...By the way i've seen some watchmakers oiling the palets of the palet- fork is that necessary? best regards
Hello Art, thanks for watching and for your question! If the winding action is heavy on an automatic watch, it's most often due to issues with the reverser wheel(s). Has it been long since it was serviced?
And yes, the pallet stones (typically the exit stone only) need to be oiled. In most of my videos I show that, but I couldn't for the life of me find the snippet of that when publishing this one 😂
@@VintageWatchServices thank you very much for your reply! i bought it 2 years ago with a big internet well-known british dealer so it was supposed to be serviced. In fact i just sent it to omega last month for a regulation (partial service) and they changed the glass, pushers etc ...(which i didn't really care, the new glass is a bit different) and now it is quite hard to wind manually (also on this watch it seems that the gasket hits the winding stem and maybe hinders the winding action) thanks anyway!
@@artblend4278 Then you should absolutely contact them and tell them that you're experiencing these issues. You should also ask them whether the crystal they put on the watch is correct for the reference. Normally they should give you a year warranty after a service so this is on them, from what I can tell.
@@VintageWatchServices hello again....yes i wrote yesterday to omega asking what kind gesture they could do on a future service. Yes the glass is carved with the logo but I think they decided to change very slightly the doming and it now looks more like a saphire...Anyway thanks for your help...have a great week end!
Hi! In what ways did Omega refined the 7751 into caliber 1151? Thank you!
Mostly small things, like using metal where ETA used plastic and better finishing
@@VintageWatchServices Thank you!
I liked it n want to buy how much does it cost ???
Hello Baqi, thanks for watching and for your interest in the watch! I haven't yet listed it and another viewer actually also said he wants to buy it :) I'll check the price and take some photos. You can mail me at Stian@vintagewatchservices.eu to keep in touch about it
I think I'd be happy with anything that was well-made and historied. But before I can graduate to trying out my hand on a watch that may be of some value for it's time, I'll need to watch out for the next Taylor Swift purchase my wife makes, so I can sneak in a full set of real screwdrivers (not ones I filed from a dollar store eye glass kit), 4 essential oils (lubricants), and oilers.
I have no idea what Era I'd be able to get the staking set, crystal press, and whatever other specialty tool you don't need until you need it (nothing else will do).
🎉
One is mainly buying the name on the watch. However, Omega makes excellent watches. I'm looking at my Seamaster as I type this.
👍
Amazingly job great reviews video
Thanks so much!
Outstanding!
Thanks! More to come, so stay tuned :)
Have the triple date a in-house movement?
No, it's still the 7751.
Hi, may I ask you a question: My Mark 40 rattles when I tap the glass with my finger. I guess it's the rotor. Is that normal? I can send you a video where you can see/hear the problem. Thank you 🙏
It's likely the rotor that's a bit loose. Take it to a local watchmaker and he will help 👍
@@VintageWatchServices thank you very much for your advice 🙏
So Omega does not manufacture their movements? They are quite beautiful.
Thanks for watching and for your question! It's a complicated story... Omega has a long and very proud story of manufacturing their own movements before the quartz crisis (although their chronographs used Lemania movements, Lemania being part of the same group of companies). They started using ETA movements during the quartz crisis to save costs, and also as the 10xx family of movements were less than enthusiastically received...
They started making in-house again in the mid 2000's, but in reality most of these movements were made by ETA to Omega's specifications. Only in the last few years have they started using true in-house movements again, but ETA still contributes technology and manufacturing, as far as I know. So it's complicated 😄
Nice one and nice job.
Thanks!
Crikey,I own one of these,how many parts including screws are there in this watch?
Hi Mervyn, I honestly don't know and never counted! 😂 I believe there are around 110 parts in the 7750, so probably some 150 or thereabouts in the 7751
I've noticed you like to put the screws back after you remove the part. How do you know they were in the correct spot on a watch that may have been "serviced" before?
Hello Matthew, that's a great question! Sometimes screws can be in the wrong place from the previous service but mostly that would lead to issues. Thus if the watch runs well after the service, it should be fine. For newer watches the technical communication is also easier to find, so you have a reference of in doubt.
Im having an issue at times where the day of week doesn’t change get stuck half way.. thought?
Hello Steven, thanks for watching! It's a bit difficult to say what might be wrong without seeing your watch, there could be a lot of reasons. You'd have to have it opened up and looked at.
Nice work and great video
Thanks so much, Itzhak 👍
Great job
Thanks so much!
When it comes to any commodity nowadays. People pay for the brand not quality. Omega is an established brand with lots of history therefore they have built a value. Building value into your product takes years and millions of dollars.
How reliable omega 1861 and how easy to service??
Hello Mohnad, thanks for watching and for your question! 1861 is essentially the 861 with rhodium plating instead of copper. They're both very high grade calibers that are not too difficult to service for experienced watchmakers, but I wouldn't recommend touching them unless you really know what you do.
@@VintageWatchServices but is it very reliable?
@@mohnnadmercedes8246 Wouldn't be high grade if it wasn't

Hello Stephen, you can find them at www.vintagewatchservices.eu.
May I ask you what the function is of the small valve{?} is for in the watch case?
Hello Mervyn, I think you might mean the weekday corrector at around 10 o'clock in the case?
only thing I cannot grasp is the value under parameters. It shows two values, bph (18000 and up) but also a number of degrees (52 very often (with 18000) or 49 with 28800. What does that number of degrees (what type of degrees?) mean ?
Thanks for watching! The lift angle is the angular rotation of the balance wheel while the impulse pin is in contact with the pallet fork. This value has a direct impact on the amplitude, seeing as the timegrapher calculates the balance wheel's rotation based on the time between the impulse pin hitting the insides of the pallet fork from each direction.
Would you consider the following timegrapher results acceptable?
-2 Sec/ day amp 250 deg beat err 0.4 mS
That all depends... What kind of watch is it and what are the results in other positions?
@@VintageWatchServices it’s the same watch as in the video, the numbers are from it sitting face up.
No other positions available at this time. It’s one I’m considering buying and was wondering if the numbers indicate it is in need of a service.
@@VintageWatchServices
I am wondering if those results show that it is in need of a service or will need one soon, I’ve heard that this model needs services quite often?
@@triumph1974 250 degrees amplitude for a 7750 is low, indeed. Timegrapher readouts aren't really that valuable, as they only show a snapshot at one point in time. Thus you will not know how the watch runs over time, how the power reserve is, positional errors etc. This watch most likely needs a service. And the 7750s don't need servicing more often than other watches, about every five years is the norm.
@@VintageWatchServices thank you for the reply, I really appreciate it.
Thanks also for the amazing videos.
great job as usual…
Thanks Ricky!
Legendary!
Thanks Paul! 😁
I noticed the chrono second hand ran very smooth. I have the same movement. Mine runs a little "rachety."
Any idea why?
Hello Kurt, thanks for watching and for your question! It can be a few things, but typically it would either be a result of dirt in the mechanism or incorrect depthing between the clutch pinion and the chronograph wheel. It might also be a problem with the teeth, but that is much less likely. Has it been a long time since the watch was serviced?
@@VintageWatchServices Hi yourself.
I got this 7751 back in 2005. It was like that when I bought it. Serviced in 2011, and 2017. Whenever I mention it to my watch guy, he just says don't worry about it.
Well, in a sense he's right, in that no one actually buys a chronograph to measure time 😁 But after a watch is serviced it should work as it was designed to do. If it doesn't, the service isn't complete.
@@VintageWatchServices Makes sense. Don't get me wrong; my guy is pretty good. When he services it again next year, I will share your take on this.
My Omegas, and other ETA movements sweep like "glass."
Thanks so much. Good luck to you.
