The more about watchmaking and repair I learn, the more fascinating the things on my wrist become. And there are still those who think it's just about telling the time.
Very helpful. I am in the process of restoring a burnt 30T2 that has sat in a cupboard for the last 50 years. It was a great reference. Love your videos.Thanks again Mark.
As usual, I really enjoyed watching your videos. I am continually amazed at the workmanship and precision of vintage watches and your skills to bring them back to life. Thanks.
absolutely fascinating. Watching and listening to this gentleman meticulously going about his work. I feel very calm and relaxed like being coach how to meditate... ohmmm. I actually own one of these. My Dad was given it when he did his national service in Cyprus when he was 18. It wasn't working when he was given it. It was knocking about in a box for as long as i can remember when at sometime i pinched it as a kid and eventually it found its way with me to my own home. My Dad knew i had it by then and let me have it as it was valued by some auction house decades ago at around £250. My Dad use to go to auctions and take me back in the 70's and it seemed to rub off on me as i've been a restored of antique glass for the past 18yrs. Anyway one of the dealers i know was into military watching and spoke about the dirty dozen watches or 12 brands that was commissioned to the British army during 2ww, the omega being one of them. This field of collecting these 12 watches is very fashionable at the mo. So got it restored by a watch repairer who specialises in military watches. I wear it as much as i can but it so happens its back with him after 2 1/2years getting the balance staff pivots made by a specialist. I'd like to ask Mark, are new replacements ready available or do you have them made? I'm not trying to catch my watch restorer out or anything, as a restorer myself it's who you know that can make the difference. I just thought, it maybe you he comes to lol! It's a lovely watch and i treasure it, as my Dad past away last August. So at least i have a personal thing of his and this watch gains more to its story. How do you rate these 30T2 movements Mark? Would they of been of a chronometer standard? Maybe too pricey for the MOD i would of thought
Omega, more than other run of the mill watch companies, has a history of trying to achieve accuracy in their watches. Personally I am of the opinion that if a watch is precisely made and well adjusted, it will be able to achieve at least near-chronometer performance. Grand Seiko and the Hamilton pocket watches are capable of keeping time within a minute per week or maybe a half minute per week. The Omega here is obviously a beautiful design and a quality crafted watch. The blue balance spring operates at a good amplitude and the coils expand an contract symmetrically, very pretty. You don't see that all the time. This Omega seems perfectly capable of telling time within about five or ten seconds a day, which is very satisfying for the owner. My Omega Seamaster from 1957 with the Cal.284 ticks away very nicely. If you have good hearing, you can hear the sound of Omega. Picture of Cal 284: photos.app.goo.gl/EZSTtMqMAF7YXzsQA
I wish you would explain why you use the different lubricants at different areas, and why some wheels and pivots, get no lubricant at all. Thanks for the informative lessons.
From what i understand lubricant density some places need less dense lubricant some need more dense lubricant but i dont remeber which places which lubricant
I'm just learning so much watching your videos. I am a collector wanting to go the distance to learn the trade and can say that you are a true inspiration for me. Not to mention the great camera work and details with your calming voice instructing every detail as you go along is fantastic. IMO, I don't think there is a more informative resource in watch servicing anywhere. Thank you for your awesome videos and expertise.
This series of Omega movements are arguable the best vintage 12 hour movements ever especially the Cal. 286. It's a shame this one was abused. Nice work on this movement !!
Yet another superb video Mark! Just done my Dad's Omega Seamaster 600 (601 calibre). Wish I'd seen this first. You make it look so easy. Keep 'em coming. I've learned more watching your videos than all the online distance learning/reading I've done so far. Best wishes, Roddy
A super video regarding a wonderful vintage WW2 Omega. Exciting history on your wrist! So much inspiration here. Thank you Mark, it was thoroughly enjoyed!!
I've been watching your videos and I'm ready to take the plunge into repairing watches as a hobby. I'm very much looking forward to the enjoyment of seeing the movement begin! It looked like the shaft of the crown (I don't know the correct name) was still rusted and I wondered why the rust wasn't completely removed. Thank you for the very helpful and quality videos.
I think he should had put a jewel on the dial side as well. It's a bit of a shame that this movement being a chronometer with a Guillaume balance and Breguet hairspring that it wasn't jeweled to the center but then this was a war production piece.
When you replaced the bushing for a jewel, was the outside diameter of the jewel the same as the bushing you replaced, or did you have to ream the hole in the bridge to a larger diameter? Is is easy to find jewel replacements for bushings without further work to change the bridge hole inside diameter? Thank you for an excellent video. I truly enjoy seeing older time pieces repaired and restored much more than new time pieces. Preserving history, is important to me.
Loved this! How clever repairing the impulse pivot. What a smashing watch. Now running like new I imagine. I really am enjoying watching these. All the best and thanks Richard
Is this definitely a re-lume job? It doesn't look very neat for sure. Could be totally wrong but an assumption would be that the main purpose would have been to be seen in the dark and the neatness wouldn't have been of much concern on a military issued watch? Very happy to be corrected on that assumption.
Wonderful video yet again Mark, so glad you decided to do it. Merry Christmas and happy new year to you, sorry I have not been on the forum much of late, hopefully can get back on there soon. I have just won a Cyma Tavannes from the mid 40's with the cal.414KA movement, gorgeous looking Tonneau with Bombe lugs. Will post some pictures soon.
Different viscosities to reduce lubricant movement maybe? I'm guessing. It,s definitely inspired me to want to get a more understanding and become a little educated in Horology especially wrist watch movements. You could pick up old watches from car boot sales and do your own autopsy on them
When you installed a jewel for the center wheel in place of a bushing. How did you maintain center for the cutting reamer? In clockwork, the opposite side of the worn hole needs to be relieved so the reamer will find center. Thanks Al T.
Thank you, love watching you and that awesome skill you have. Bet you can teach Archi a thing or two about watches! I wish I could do what you can do, my eyes don't but I like Watches. Thanks again & Mary Xmas !
Great video! Looking forward to your future works. It's nice to see that you put a lot of work into the video, and it really shines through. You're also the inspiration that made me change from my current education to the watchmaker education. So thanks a lot! :)
Mark, great videos and thanks for helping educate us in the art of watch repair. Any videos on tools and basic tools one needs or the tools you use to do specific jobs? Thanks!
Hi, great video as always!!!!! I am a little concerned with that dial and watch hands which appear to have deadly radium!!! Unless it has been relumed with a less deadly paint would you consider finger cots or at least gloves to protect yourself from any radium dust ? Just curious!!!1
Amazing video Mark,thank you. One quick question, when you replaced the worn bearing with a jewel did you turn down the staff to suit a standard size jewel or was the jewel fitted and then reamed to suit the staff? Was the jewel a press fit into the bridge or do you use shellac to mount it too? Sorry if being a pest but find the repairing side fascinating. On a high note , I can now confidently strip and reassemble a Valjou 7750 and it still runs! Done my one several times now and getting more confident. This is directly down to you so thank you. It is hard to quantify just how good this makes me feel but it's right up there with the very best feelings ever!
I love to watch you work, pardon the pun. I'm amazed at your precision & fine motor skills. How you can match the screwdriver exactly with the screw slot boggles my mind. Your patience is uncanny. Very enjoyable video.
Thanks Mark.... Do you clean the crown and stem ... Or not necessarily ... Beautiful omega.. Nice job... It is slow at first but I find that the Seike auto I am doing" I went on line and bought a few dead movements and as I am rebuilding I look to the old one for what goes where... Boy I have lost a circlip and the incabloc brass spring for top of cap stone.. Both which I have found... I,ll have to think my way around not losing anything.. One thing comes to mind is the quality of your tweezers and your ability to use the,... Are you in Australia now.. Thanks a load for your help..
I love Your videos. All the repairs look so easy when You do it :) I wish I had such a skill. I don't know if You want to share this information, but I wonder what watch do You use everyday. I wish You and your family happy new year ;)
Great video Mark. Subscribed. Do you have more detailed video on how you choose jewel size and how to source Seitz jewels. I have put in a few jewels but not even remotely sure what I have is even Seitz jewels. Choosing a reamer is not always straight forward as there is suppose to be I think 1mm smaller diameter. Maybe my measuring methods are not so great. Would very much appreciate more details in this regard. Happy New year and Thanks. RJ
Lots of greetings from Pakistan. I've been enjoying your videos since about 3 years. I do really respect & honour your skills and presentation. I also noticed that matchmaking requires lot of patience & a cool mind. Well I have a vintage automatic Omega Constellation. I got it serviced from Omega representative in Karachi about 10 years ago. It is lying in my drawer and needs your attention. Would it be possible if I send it to you?.
Hey, novice watch smith here, love your videos. Quick question on something Ive always struggled with. How do you get the impulse pin to line up with the pallet fork horns? When reassembling I always get messed up with it and have to spend a lot of time just to get them lined up properly.
i have a ETA 6498 and when I put it face up it makes other sound (additional sound) and when I turn it the sound stops. It was repaired and i think they did it wrong. Soma idea about this. thanks
Hi mark hope that your well. Only asking have you ever come across a a problem in evolving a balance wheel that when you set the timing /beat dial side down and its OK then when you turn the watch dial side up it then gains i'e 215 seconds or more is it because their is a lot of play between the the jewels and staff ( seiko 7s26a movement ). do you have any suggestions or just have a average / new balance. best regards ady p.s the spring is clean and not touching
Watch Repair Channel hi mark the amplitude is good 0.1 up side down or dial up 21600 beats per minute their is a little play the balance pivots / jewels are fine strange !! ady
TommyTightPants0115 0.1 may be referring to the beat discrepancy. The amplitude is measured in degrees. For example 270º is a reasonable amplitude when the watch is mostly wound up.
Hi mark another fantastic video ive learnt so from these videos but only asking do we oil the pallet fork pivots if not and why. I know about oiling the exit jewel.also can we see some videos on timing and calibrating the movements best wishers and merry xmas ady
Hi Ady, nice to hear from you :) It is not recommended to oil pallet pivots as the oil will create too much drag and impede the movement of the pallets as they move from banking to banking. Although some watch repairers may use a very low viscosity oil, I am of the opinion that it can cause more problems than it would solve. It is the same with the minute recording wheel on a chronograph - oiling the pivots will potentially impede the movement of the wheel rather than help it.
Why there is a cut in the balance wheel (16:32)? It is supposed to be so I assume but why is it not one whole wheel instead? Is there a purpose for that cut in the weel? Nice video, once again, thank you!
I really enjoy your videos and you always seems to do the overhauls "guided by the book". But why do you choose a smaller screwdriver than the screw head? I think that you should have used a same size screwdriver, even if the screwhead is already badly damaged by years of abuse.
Its a habit I personally have adopted over the years, I don't always do it. The mentality is that when I first drive the screws in I use as little force as possible to help prevent broken screw heads, a smaller bladed screwdriver helps to enforce this policy. I then go over the screws once the watch is assembled and carefully tighten the screws further if required, especially automatic works screws as these can tend to work their way loose over time, but thats another topic :)
I believe this is a bimetallic temperature compensating balance, also known as a Guillaume balance. The slots in the balance wheel allow for expansion and contraction.
The more about watchmaking and repair I learn, the more fascinating the things on my wrist become. And there are still those who think it's just about telling the time.
Very helpful. I am in the process of restoring a burnt 30T2 that has sat in a cupboard for the last 50 years.
It was a great reference. Love your videos.Thanks again Mark.
***** Thanks for watching. We use shellac because you can re-heat it and make adjustments if needed. You can't do that easily with epoxy for example.
As usual, I really enjoyed watching your videos. I am continually amazed at the workmanship and precision of vintage watches and your skills to bring them back to life. Thanks.

This series of Omega movements are arguable the best vintage 12 hour movements ever especially the Cal. 286. It's a shame this one was abused. Nice work on this movement !!
I own a WWW 30T2 so this video is personally an absolute pleasure to watch. Thankyou.
I'm very glad you chose to film this as I found it very informative and interesting. You are a master at your craft.
It’s a pleasure to watch work Mark. One can never get enough of watch repair videos!
A real pleasure to see a craftsman at work. Many thanks.
Yet another superb video Mark! Just done my Dad's Omega Seamaster 600 (601 calibre). Wish I'd seen this first. You make it look so easy. Keep 'em coming. I've learned more watching your videos than all the online distance learning/reading I've done so far.

A super video regarding a wonderful vintage WW2 Omega. Exciting history on your wrist! So much inspiration here. Thank you Mark, it was thoroughly enjoyed!!
As a student in watchmakers school I find your videos interesting and enjoyable to watch. Thanks for putting out the awesome content.
I have been looking for a watch repair school.....are you attending one in the US? thanks, Len
No problem Brownie, and good luck with your course :)
lenspaulding Gem City College in Quincy, Illinois.
I've been watching your videos and I'm ready to take the plunge into repairing watches as a hobby. I'm very much looking forward to the enjoyment of seeing the movement begin! It looked like the shaft of the crown (I don't know the correct name) was still rusted and I wondered why the rust wasn't completely removed. Thank you for the very helpful and quality videos.
Wow! Upgraded to 16 jewel along the way! Brilliant repair!
I think he should had put a jewel on the dial side as well. It's a bit of a shame that this movement being a chronometer with a Guillaume balance and Breguet hairspring that it wasn't jeweled to the center but then this was a war production piece.
Your videos are very enlightening and entertaining at the same time!
Can you please do a Accutron watch? Really appreciate all your time & videos. Thanks again! God bless!
Wow. Adding a jewel. I didn't know that was possible. I'm learning a lot.
Very useful indeed! I just acquired a vintage Omega with a 266 movement - and this will be a great guide to servicing it.
As a static model builder who details what I build to a high level I feel like I missed my calling when watching your tutorials.
When you replaced the bushing for a jewel, was the outside diameter of the jewel the same as the bushing you replaced, or did you have to ream the hole in the bridge to a larger diameter? Is is easy to find jewel replacements for bushings without further work to change the bridge hole inside diameter? Thank you for an excellent video. I truly enjoy seeing older time pieces repaired and restored much more than new time pieces. Preserving history, is important to me.
Another great video.
We have here an improvement 15 jewels movement that became a 16 jewels, i'm i right?
Loved this!
How clever repairing the impulse pivot.
What a smashing watch. Now running like new I imagine.
I really am enjoying watching these.
All the best and thanks
Richard
Mark, I really enjoy your videos. They are invaluable for me in my watch repair hobby. Please keep the coming!
Thanks for the clip as always. I have a Omega 30T2 too, lovely calibre. Shame about the botched re-lume job on this watch - what an eyesore!
Is this definitely a re-lume job? It doesn't look very neat for sure. Could be totally wrong but an assumption would be that the main purpose would have been to be seen in the dark and the neatness wouldn't have been of much concern on a military issued watch? Very happy to be corrected on that assumption.
Thank you for spreading your knowledge and your skills, it's a pleasure to watch your videos and it's quite motivating to me too ....
I love watching you work and listening to your thoughts and feelings. Thank you.
Wow, that little guys had a hard life. Glad to see it working again.
Fantastic work. I never had to use shellac and you seem to do it quite effortlessly. Your videos are great!! thanks!
Wonderful video yet again Mark, so glad you decided to do it.
Merry Christmas and happy new year to you, sorry I have not been on the forum much of late, hopefully can get back on there soon.
I have just won a Cyma Tavannes from the mid 40's with the cal.414KA movement, gorgeous looking Tonneau with Bombe lugs.
Will post some pictures soon.
Nice to hear from you Ian - Merry Christmas to you also :)
I had to hold my breath watching this. Lovely work.
Not to neglect the rest...You are the best! Jerold Moore
Nice work. Why did you leave the shaft on the winder rusty?
As always Mark, your videos are second to none!!
Thank you Chuck. I appreciate the encouragement.
Different viscosities to reduce lubricant movement maybe? I'm guessing. It,s definitely inspired me to want to get a more understanding and become a little educated in Horology especially wrist watch movements. You could pick up old watches from car boot sales and do your own autopsy on them
Hi Mark: Your work is excellent.
Greetings from Argentina.
What a lovely movement that is Mark, thanks for yet another superb video, loved the shellac advice.
Cheers Micky. Glad you enjoyed it :)
Great videos! Thanks so much for posting these and taking the time to produce them. This helped me to get my old omega seamaster 267 going again.
When you installed a jewel for the center wheel in place of a bushing. How did you maintain center for the cutting reamer?
In clockwork, the opposite side of the worn hole needs to be relieved so the reamer will find center.
Thanks

great video!..I have the Omega 2500c movement..I watched your video on the complete service of the 2500c.
Thank you, love watching you and that awesome skill you have. Bet you can teach Archi a thing or two about watches! I wish I could do what you can do, my eyes don't but I like Watches. Thanks again & Mary Xmas !
Thank you - merry Christmas to you also Werner :)
Great video! Looking forward to your future works.
It's nice to see that you put a lot of work into the video, and it really shines through.
You're also the inspiration that made me change from my current education to the watchmaker education.

excellent video and narration. nicely explaining the details and terminology. thanks ( from Toolmaker and watchmaking Novice )
Hi Mark, I would like to clean my watches but I need the fluid to clean them with, I have pondered sending them to someone until I get the fluid.
Im now putting a like on every one of your videos mark to compensate for the sad people that put a thumbs down ☺☺

Another great video! And I like the watch. I'm going to look it up and get more info on it.
'tis a great watch.
I love Your videos. All the repairs look so easy when You do it :) I wish I had such a skill.
I don't know if You want to share this information, but I wonder what watch do You use everyday.
I wish You and your family happy new year ;)
Hi Mark I love your videos. How did you get into watch repairing and did you have any formal training? cheers
Love your channel, it fascinates me.
Are jewels universal? If I buy an Omega with 8800 or 8900 movement will it be always servicable?
Great video Mark. Subscribed.
Do you have more detailed video on how you choose jewel size and how to source Seitz jewels. I have put in a few jewels but not even remotely sure what I have is even Seitz jewels. Choosing a reamer is not always straight forward as there is suppose to be I think 1mm smaller diameter. Maybe my measuring methods are not so great. Would very much appreciate more details in this regard.
Happy New year and Thanks.

no reply...
Thanks Mark, nice one as always. Have a merry Xmas and a Happy New Year
Thanks David, same to you :)
When you remove the crown from a 30t2 do you want it to be in the time set position? Thanks!
Lots of greetings from Pakistan. I've been enjoying your videos since about 3 years. I do really respect & honour your skills and presentation. I also noticed that matchmaking requires lot of patience & a cool mind. Well I have a vintage automatic Omega Constellation. I got it serviced from Omega representative in Karachi about 10 years ago. It is lying in my drawer and needs your attention. Would it be possible if I send it to you?.
Morning Mark, I know this is for comments, but was thinking maybe outhers might have this question. Are all balance springs the same size?
Awesome video dear mate. Great work performed and looking for new upload from you. Regards,
Beautiful work!!! You are a true artist!! Much respect!
Nice neat work. What camera are you using? If you don't mind sharing..
Hey, novice watch smith here, love your videos.
Quick question on something Ive always struggled with. How do you get the impulse pin to line up with the pallet fork horns? When reassembling I always get messed up with it and have to spend a lot of time just to get them lined up properly.
AppleseedInTheShell This is discussed in this video: ua-cam.com/video/uvMCNyrDZQo/v-deo.html
Hope that helps :)
i have a ETA 6498 and when I put it face up it makes other sound (additional sound) and when I turn it the sound stops. It was repaired and i think they did it wrong. Soma idea about this. thanks
Very nice and useful video ...may you show us a quartz omega watch repair
Hi mark hope that your well. Only asking have you ever come across a a problem in evolving a balance wheel that when you set the timing /beat dial side down and its OK then when you turn the watch dial side up it then gains i'e 215 seconds or more is it because their is a lot of play between the the jewels and staff ( seiko 7s26a movement ). do you have any suggestions or just have a average / new balance. best regards ady p.s the spring is clean and not touching
What does the amplitude look like?
Watch Repair Channel hi mark the amplitude is good 0.1 up side down or dial up 21600 beats per minute their is a little play the balance pivots / jewels are fine strange !! ady
TommyTightPants0115 0.1 may be referring to the beat discrepancy. The amplitude is measured in degrees. For example 270º is a reasonable amplitude when the watch is mostly wound up.
How much would something like this cost? I have an Omega Seamaster Deville day date from the 1970’s with cal.1020
Hi mark another fantastic video ive learnt so from these videos but only asking do we oil the pallet fork pivots if not and why. I know about oiling the exit jewel.also can we see some videos on timing and calibrating the movements best wishers and merry xmas ady
Hi Ady, nice to hear from you :)
It is not recommended to oil pallet pivots as the oil will create too much drag and impede the movement of the pallets as they move from banking to banking. Although some watch repairers may use a very low viscosity oil, I am of the opinion that it can cause more problems than it would solve. It is the same with the minute recording wheel on a chronograph - oiling the pivots will potentially impede the movement of the wheel rather than help it.
Great job, love to watch you enjoy your skill.
Mark were you having a off kind of day? did you not see the rust on the winding stem or were you testing your students visual awareness ? Regards
excelente video !!!! I love my Longines 23Z 1960 saludos desde México
Nice video. The crown is rusty though
Why there is a cut in the balance wheel (16:32)? It is supposed to be so I assume but why is it not one whole wheel instead? Is there a purpose for that cut in the weel? Nice video, once again, thank you!
The spit allows the balance to expand and contract with temperature changes which helps with watch time regulation.
I did the same service today ! ! I just have one question, what is that blue oil ? Is it better ?
Cheers from France :)
9501 :)
That was magnificent! Thank you for making this video!
What can I say, Mark you did it again.
Thankyou for another fine video
Thanks :)
I thoroughly enjoyed that. Cheers.
I really enjoy your videos and you always seems to do the overhauls "guided by the book". But why do you choose a smaller screwdriver than the screw head? I think that you should have used a same size screwdriver, even if the screwhead is already badly damaged by years of abuse.

👍thanks for sharing. you make it look easy.
You are amazing and attention to detail.
Are those Grobet diamond files?
Very good work thanks for you keep moving 👍
I have this model does anyone know if I can get a year ref from the number on case back
Are these the 2 jewels missing when they say 17 is the min you need?
hi could I ship my watches to you for repair?
Excellent work!!
Cheers Tony :)
Spectacular - as always.
You would make a terrific brain surgeon and I'm not kidding.
Haha....when you removed the click spring it gently bounce over on to the bridge. When I remove a click spring it shoots in to a low earth orbit.
i noticed the balance wheel is not whole it has a cut in it is that normal ? or just a part of manufacturing
I believe this is a bimetallic temperature compensating balance, also known as a Guillaume balance. The slots in the balance wheel allow for expansion and contraction.
That crown stem was very rusty and you didn't clean it up? Anyway, very interesting as usual.
Very good thanks for you 👍👍👏👏👏👏👏👏👏
