Seiko 8306 Seikomatic-R Full Service - Watch Restoration
Вставка
- Опубліковано 31 січ 2021
- HI Guys in this video I will attempt a service of this wonderful Seikomatic-R from 1966. A 30 (functional) jewel 8306 movement that I believe to be a high calibre Seiko movement for its time. This watch was sent in by Elliot from The Retro Future UA-cam channel. He bought this watch as a gift for a family member but it was not running right so sent it to me for a repair and a vlog on it.
Elliot took this to a watchmaker who opened it up and looked at it then closed the back and gave it back saying he did not do Seikos.... Terrible really.

Do you take on Seiko commissions? I've really been struggling to find someone and I have a few!!
@@MrLukealbanese hi Luke. It would depend on what they are etc. Email me on michael@myretrowatches.com and let me know what you have. Thanks
@@MyRetroWatches will do.
@@MyRetroWatches you have E mail 😊😊
do you recall if the mainspring is right or left hand wound ?
Hey Mike!
Thank you so much for doing this for Ian and I. He will be so pleased and I am sure he will watch this video with a beaming smile on his face.
He was so pleased with the watch when I gave it to him, but after wearing it for a few days it was clear it definitely wasn’t a reliable time keeper. I took it into apparently the best watchmaker in the island (I live in Jersey Channel Islands) and he turned it down. Said he didn’t do Seikos.
This means the world to us and I am so grateful! Thank you so much. Thoroughly enjoyed watching this video.
Thanks for the opportunity to work on it. Although it might have been frustrating at times the challenge to work on a new movement is great.
I learnt allot on this one , mainly to have second thoughts if someone else asks for this model to be serviced!
Pleased to help your family and glad the watch will be appreciated by Ian for decades to come.
It's sad that they turned down working on your watch but I suppose understandable. One of the things that turned me off of mechanical watches is finding out what was involved in upkeep for them. More and more I find myself living in a disposable society and I suppose a lot of others are in the same situation.
When I was a small boy my Father and Grandfather sometimes took me along to visits to watchmakers to get their watches worked on. They were magical places like mad scientists workshops where I got the feeling that these people could fix anything, like wizards of some sort. I remember my Father taking Timex watches to them and they didn't even bat an eye, the most they ever said was that they would try but couldn't guarantee anything... but somehow they always did fix the watches.
@@MikeRobertsGaming For most mechanical watches, services isn't the 5 years or kablooey it is with a Rolex, most Vostok's will go 20 years without a tickle with the tweezers as will most Seiko's but its become such a rare thing a watchsmith that they can charge the earth and their high prices does put people off. There was a chap in Wales called Dafydd who used to do £20 specials for folks which was a stripdown, clean and oil and tweak the timekeeping but I heard he retired.
Not much of a watch servicer if they can't tackle a Seiko :( You will have to post him the link and say "Yep, this is how its done..." or maybe do a video putting him to shame lol
@@dodgydruid It is like a Mercedes mechanic turning down work on a Honda.
Coming from Elliot's channel 🙋 Hope I'm *on time* 👀
Thanks for dropping by. Appreciate any new audience .
I came from Elliot's channell. I love watches and I'm glad I found your channell
Thanks for coming over and your subscription
Great video! I recently worked on a 8346 Business-A, and really like the design of this movement series. The reason it didn't unwind by releasing the click is that the reverser wheel for auto winding was still in place, and since it can only spin one way (it has tiny internal clicks too) it won't let the ratchet wheel unwind. You need to disassemble the auto winding at least partly before you can let down the spring. This is the same for all Seiko movements that use reverser wheels (83 series, 51 series, 52 series and 56 series).
That makes sense now but I would not have known this otherwise. Great to finally have an answer as it had me thinking for a while now.
Appreciate this!
Well done Mike, as always a job well done. Always a bonus to see part of the struggle with springs etc. It allows viewers to understand just how hard it can be working on unfamiliar movements. Big thumbs up :-) Forget to mention before...I love the thumbnail on this showing all the parts!
Hey Vince mate, thanks for dropping in and also for sending @elliotcoll over to me.
About time you tried another watch mate!
@@MyRetroWatches No problem Mike :-) I have been tinkering with them but not on camera. If I can find something interesting then I will attempt another on camera :-)
Video just popped up and I am wearing the identical watch. Was one of my grandfather’s. It was last serviced 10 years ago. It hasn’t got much wrist time since and it’s pretty accurate.
Nice one. Damn tricky movement I have another on my bench for a friend that I keep putting off.
@@MyRetroWatches thanks 🙏
Wow, what a movement! Cop that Rolex! I guess from before Seiko took on the keep it simple, make it cheap design. Makes the 6309 look positively agricultural. Thanks Mike, great help for us.
I apologise in advance for some of the shaky camera work and lighting. My new iPhone 12 pro that I film on has some weird HDR settings that record and play back really nice on the device but not once edited and encoded to MP4 format for YT. Shaky camera is because I keep knocking my tripod....
My Retor watches you are good at restoring vintage watches ⌚️ my friend ⌚️
I haven't been up to doing any watch services recently so I was so glad you posted this video and I could enjoy this hobby through watching you service this watch. I hope to be back to the bench by the time my 6138 (hope I got that right, it's been so long coming I have forgotten the number, nicknamed square eyes anyway) finally arrives. Thanks for the time and effort you take with these edutainment vids, stay safe. 🙂
Thanks. I’ve a 6138 to do also , a bullhead . It will be filmed despite never actually servicing one in my life!
It will be over a few episodes I feel.
Mr. Mike, thank you so much for the smiles you put on faces, and, yes, springs are our worst friends, I guess... Cheers!
Elliot definitely did his fans a solid on this one. Fantastic job.
Well sir, thank you! I just finished servicing my first Seiko 6118 . NexT îs a 7009. Im preping FOR my bellmatic. 👍 im just tired of my watchmaker telling me: im busy or it s an old movement.🤔
Good for you! It’s a good reason to learn yourself. Many pros don’t touch these watches and prefer to do bigger brands. I have fully understand why. As a business if someone wants to pay the price then do it!
Good luck . I have a 7025 series, I think my 1000 sub giveaway. The 7025 is identical In many ways to the 7009 so you might find those videos useful.
No one's probably going to read this because I'm late to the party, but I was just about to buy that watch on ebay until I found this video and realized there is no way I can service tha! Way over my head...amazing movement though and amazing job...seems like the hardest job you had yet!
I own this watch (actually wearing it right now) and I absolutely love it! So awesome to see the mechanics of this movement. I really enjoyed this video. Amazing job.
Keep the good work 👏👏👏
So good to have you back! waiting for the next one! Nice music!
Hi there! Came over from Elliot's channel. I love watching people who are good at what they do. Have a sub!
Thanks for coming over I appreciate your subscription.
My Retor watches ⌚️ the owner vintage seiko 8306 seiko matic-R from 1966 is awesome my friend
Thank you very much for your videos. Thanks to you, I have learned a lot and have repaired many watches that I thought had no solution. In October 2020 a car caused me to have a motorcycle accident and my left arm is bad but my wife has been very involved in the world of watches, since now she helps me a lot more, and she also watches your channel now, thank you I do not give up on this and I continue to fix and clean my watch collection.
Thank you again! Very good focus, cameras and voice.
Thank you. Sorry for your accident for something to stop me doing this hobby would be devastating. Hope your can recover. Good your wife has stepped up to help!
Thanks on the feedback on the video quality , personally I thought it was worse so pleased to hear otherwise.
Fascinating!
Job well done mate 👍
Probably best movement Seiko ever made in the 60s.
Elliot brought me here! You’ve got a new subscriber ☺️
Thanks , I appreciate that. Welcome
Fantastic Mike, a real education.
My Retor watches your utube videos are awesome my friend
Absolutely brilliant presentation Michael Bolton. I have learned so much from the MyRetroWatches site. I love the Seikomatic range of watches from the 1960s. I think they are a hugely under-rated design classic. As you say, they are not for the beginner or the faint-hearted particularly if you work in a room with a deep pile carpet!! Thanks again and keep up the good work.
haha pile carpet! yes that would be the worst nightmare. Nice comment Mark thank you.
Yeah after a few centuries those milliseconds really ad up :)
Great job Mike. You do these service videos on UA-cam the best IMO. This movements looks like it was very challenging, just waiting to catch you out. Those jewel retaining clips yikes plus all those springs!
So beautiful. Thank you.
Just for the algorithm and to say nice job done on that old Seiko!
Well Done Mike really enjoyed the video, you have the patience of a saint. Mick 👍🍻
An illustration of why it is worthwhile to have one or two parts movements on deck before launching into repair of something for which replacement parts are scarce. Can't find an absconding spring or broke a yoke? No worries; I have two more if needed.
Lovely watch Mike. Jeweled MS arbors from the factory are just brilliant. Nice result and thanks for sharing your work. John S
Interesting.
love your channel mate I'm trying to learn this craft wow there's a lot of tools though i thought all I needed was some small screwdrivers lol
Great video Mike, I enjoyed it, and that is a nice watch, it turned out beautiful, nice job!
Hello! A very nice and detailed video. I always admire your work. I also collect Citizen and Seiko watches myself, but I don't dare to clean them myself. Thank you for your explanatory videos. Greetings from Germany
Thank you very much!
A job well done, great video.
Nice video, many thanks!
amazing work as always
seikos are my love
Great Video. I never worked on a 8306 before, but it seems like a very nice movement to work on, think I have to try to find me one.
Good work.
Excellent video again, as my course stopped during the total lockdown here, I am learning a lot from your videos. Much appreciated Mike.
Thanks for watching my channel and if you have learnt a few things in the process then this is fantastic.
@@MyRetroWatches Learnt and still learning a lot, also very relaxing to watch the videos...:)
Great job! Like always! Hello from Puerto Rico
Great video! I've heard you and many others say they don't have the spec sheets for movements they are working on. If you join AWCI (A reasonable annual membership), they have a pretty healthy online library of tech sheets. Over 200 pages of just Seiko movements, this one for example is on there.
Hi Mike ,new camera technique really makes a more professional video ,no more fingers filling the screen! Well done on servicing this lovely old 60s timepiece.
At 32.00 , the pivot hole next to the jewel looks elongated , and maybe it would affect whatever wheel is pivoting on it.
Thanks for all your hard work,Regards,John.
nice watch
Interesting clock in the background. Looks very 70's. Reminds me of those old old Hamilton and Unicar watches.
It’s a Seiko transistor clock. Really cool but a loud tick. The battery is always out for filming!
@@MyRetroWatches Thank you.
Great stuff Mike!
I'm working on the 27 jewel version of this movement (8346A) currently and I was surprised to find that this movement doesn't have a hacking lever.
I've got another Bombay Bad Boy en route, a Seiko 7009-5650 in a two tone square case, from my usual "chap" and choosing this one because it has applied markers and logos as well as has a textured dial finish with dial code matching the caseback, looking forward to that one :) My in the sin bin 7009 has the ferrule end of the winding stem snapped off and I can't seem to get the bugger out, added two new Pulsar dancing hands to the collection, the V601 I am wearing now and got an insanely rare Pulsar V693 yacht timer and I added a 4 register Sekonda Classique chronograph to the collection as well. Got an original, still in plastic blister Elektronika LCD Soviet digital watch incoming as well, so its all been good thanks to the gods of ebay being kind :D
Thanks for another great video. I had one Seikomatic-r from 1965 coming to me, but sadly it was damaged during transport so I returned it to seller, still looking for a 1965 Seiko.
That’s a real shame. A nice movement that I would want in my collection now however not the nicest to work on given those crazy springs!
Great job Mike, you must be related to Richard the Lion heart!!. 😂. Owners will be delighted. Thank you. Adrian
Haha
I'm a Seiko superfan. I have that exact watch.
i have the exact same caliber but in a very horrible condition :( it's nice to see a good example getting some tlc !
Great video, thanks so much for candidly showing us your servicing a new movement! As for one of the feared springs you mention, for some movements I believe you can just slid it out/into the recess when the plate is not even removed... but may be I'm wrong, just my two cents!!
Thanks. Kinda found my method with those springs and dare not change as they are so easily lost
Elliot sent me!
Top, top, top!!!
Elliot sent me here.
thank you for stopping by to have a look.
@@MyRetroWatches Thanks for commenting!
This movement was my first one that I stripped down after watching your videos and getting enough confidence to 'have a go'. Should have watched your video on diasprings as well as those things are evil! I also lost the tiny circlip but they are available from Cousins after digging around. Should have started with 7005 movements as those are much simpler and a great place to learn. Thank you for your inspiration and hopefully I can move onto the more complex stuff in the future.
Wow!!! For you to start on one of these is deep deep end stuff! I’ve actually another to service here and I keep putting it off.
Yan, if you can do this movement then your well on your way into this hobby. I really do find it amazing what some people start their journeys on.
If I have inspired you in any way then job done for me as it’s that that inspires me to produce more content.
@@MyRetroWatches many thanks, I'm cheating a little as I've worked as a aircraft mechanical technician for 25 years so there is a lot of transferable skill despite it now being at a much smaller size. Very satisfying work, especially when they arrive in a state. I did kill 3 diafix springs in the process, luckily buyee Japan has turned up some that are not 8 Euros each! Oh and just in case the circlip is part number 854830 'snap for reverser idler' £1.50 from Cousins for your next one on the bench. 😁
came from Elliot awesome video just subscribed 😁
Thanks for taking a look. I appreciate the sub too.
Excellent video Mike. Always tricky working on a movement for the first time.
@39:52 I think the circlip was upside down and that's why it seemed loose. This circlip is slightly domed and pressed down, it would be pressured into sitting in the groove of the post. BR, Tony
Thanks. I had tried that circlip every way possible. Video shows a few seconds but I was on that a good ten mins. It would fit up or down but would not secure on the undercut on the post. Nightmare thing
@@MyRetroWatches OK, fully appreciate that you might have tried all other ways. The circlip looks fragile and probably wouldn't like to be removed too often. Cousins have parts for the 8306a movement, but no circlip. Otherwise, they only sell the pusher variety . Your use of a pusher circlip was then the only option. Well improvised!!
The nasty little gears with the circuit on is where you remove the power in the mainspring, just take the plate off hold it with Pegswood and release the power , simples !!
Cool watch movement. The microscope is great. Those pivot holes are well worn out.
was there a pivot hole without a jewel?
@@MyRetroWatches 31.07 in, next to the diashock.
you sound just like dokter Campbell.Same voice, another speciality
great video and walkthrough, certainly a horror caliber to service, I'm about to look into mine because it has power reserve for only ~15 hours and my watchmaker told me that one part needs to be replaced, but he doesn't have it... So I don't really care
go for it. its not the easiest calibre due to the springs but take care and its doable. some people use clear plastic bags to cover the movement to remove and replace springs so they dont lose them if one wants to go rogue.
@@MyRetroWatches great advice, will try!
The ratchet wheel has a pretty good scuff/rub mark on it. I suspect that was the reason it was not wanting to unwind the main spring.
That’s a good point. To be honest since disassembly I didn’t think any more of it. Definitely an odd setup not giving you a screw to help with the click to release the tension. Things could easily go wrong .
Also looking for
an original strap,
A white dial
and intermediate date wheel for a 7009A movement,
also the size or how to determine the size of a Seiko 5 Automatic crystal.
Hi, I recently fixed an 8306 I picked up and the 4 springs on the dial side were fitted in the wrong position and 1 was a bodged replacement, luckily I sussed the missing one is also used in a Bellmatic so replaced it, working blind with no reference when parts are bodged or incorrectly fitted is a nightmare!
That sounds like a nightmare! Those springs are not nice. I like to think I can do them better when the camera is not there....
How about a video of the internal workings of the Smiths English Clock System Interval Timer?
Thank you for sharing! My 8306a's manual winding function takes quite a bit of force and I'm not quite sure why. I've serviced the main spring but alas without much improvement. With the crown wheel taken off the crown will turn smoothly as expected. Could it possibly be a non original main spring that's the culprit? The auto wind works properly.
Hello. Difficult to say, it’s possible but I’m reality you have to get the mainspring right or they won’t wind into the barrel. Too strong will mess with the beat and the watch would run badly.
Have you serviced the whole watch? Barrel arbour ports greased? Same with the winding pinion and keyless.
@@MyRetroWatches Hi, thanks for the reply and suggestions. I had checked all the parts, but now suspect the crown itself to be the culprit since it's a non original one and it might not be fitting perfectly, hence causing a resistance. Whoops. I think I've learned my lesson to always test the winding before casing the movement!
@@DaKarst that would be my suggestion. Remove from the case and see how it winds.
Grease the crown gasket too.
I believe you 😅😊 approx 1.01
What solutions do you use in the cleaning machine?
L&R fluids
Hi Mike
Great videos love them all.
Can you please let me know how you film your microscope shots? What camera you use?
I would appreciate it very if you could let me know.
Thanks
Yes
How do you remember, particularly with an unfamiliar/vintage movement, where all the parts go back ? The screws are insanely tiny too !
Sometimes you dont and thats why its important to take photos. Generally though you get a good understanding and keeping parts in trays and then laying them all out before assembly helps considerably.
Elliot sent me 🙃
Thanks for dropping by
Could ya tell me the name of that song, from 32:50 to 35:09? It doesn't sound like The Bristol Stomp by The Dovells. It has some other connotation to it. I don't think I've heard 🤔 it. Your friend, Jeff.
Great content and will start servicing some old cheap watches later in the year. 👌🏻👍🏻 🏴
And just to let you know that when you try link for stitched cotton mops, it gives you a picture of a dog!!! 😬 just thought I’d let you know do you don’t miss out on cash for channel 👍🏻🏴
Nice one!
Thank you for an educational and entertaining show.
A question please: the Seiko movement you are working on here, what metals are used? Mainly:
A. The main plates, the bridges and the cocks look like they are made of aluminium. Are they? Not steel?
B. The pinions, the shafts, and the escape wheel look like hardened steel. Right?
C. The "large" wheels (gears) look like brass. Are they?
I am not asking about the balance, main spring and hair spring. These I understand to be complex.
Thank you for any constructive reply.
Simon
you ask some interesting questions that I cant answer for sure. Many mainplates are a brass alloy time material that are then plated. When you see wear you see the brownish colour coming through.
I dont think staff or escapes would be hardened. They are so fine and to harden material on this scale would make them distort for sure. you could not pre harden and then machine. So as far as I know it will just be a carbon steel. Dont forget a professional watchmaker would be able to turn their own staffs should they need to.
There is no aluminium in watches.
Wheels are generally brass but also steel wheels are found.
One more question:
At minute 31:36 is an image of 3 holes. 2 are jeweled, the middle one is not and it looks quite elongated. Is this actually a bearing surface/hole? If so, I think it should be sleeved, or jeweled.
Am I right? If so, can you help us visualize the process?
Thank you so much!
Simon
I see what you mean and as I have given the watch back the owner I cant check but looking at the dial side rebuild the hole is filled. So my guess is that its a location pin hole for one of the bridges on the movement side.
Hello Mike! I am the owner of a SEIKOMATIC-R 8305-8060 DIASHOCK 30 JEWELS from 1967. I have a question regarding the 8305 movement. The direction of the rotor to wind the mainspring is unidirectional clockwise? I'm not an expert at all. I would like to know if in the settings of my winder, do I set it to unidirectional clockwise or bidirectional?
From memory uni. I don’t recall any Seiko being bidirectional
First video to mention the securing of the dial screws..
Found out the hard way as I threw a few sets away in the early days of ultrasonic cleaning...doh!
They are a complete git to fit back in once they fall out.
Thanks for watching .
Bah! The only reason I found this video is because I need to know how the crystal comes off! I've got a 1967 Business-A, and before I do anything I was trying to find out if the crystal comes off from the front (the bezel has a little spot for removal), or if I have to take the movement out. Just wanna replace the crystal and get out a tiny piece of hair I noticed.
Hi, are you still looking for any watches to look at and make videos from? I have some old Russian Raketa watches with a square "tv" dial. They are automatic, but pretty much went bad from oxidation and non use.
Not currently. If you saw my last video on whats to come in 2021 I have a full year / 18 months of videos ahead.
hi Sir, bought a Moeris Swiss watch, the hand wounding had no end stop, winding it for 5minutes straight ! it help it only working no more than 7 hours, is the mainspring Broken? thanks
Sounds like the bridal on the end of the mainspring has snapped so it is not locking to the barrel.
@@MyRetroWatches thanks sir, you're a real gentleman, hope soon see video on EFFEM watches one day, real bargain quality wise
What is that movement holder.....Want one of those!!!
It’s vintage. Called a pioneer.
The day wheel is only in English!
My Retor watches ⌚️ my hobbies are painting pictures 🖼 and listening to shortwave and ssb iam thinking about getting my Grms license and mybe my ham license some time
Lift angle ?
Use 54.5
How on earth does hair and dirt get inside a hermetically sealed watch? I mean even if some tiny bit of air moves in somehow, the hair certainly shouldn't. I mean, have you ever found dead bugs inside a watch?
I would say the stem is the big culprit there, a small hair gets tangled and slowly wormed into the case workings.
You don’t know how many times it’s been opened. This one has 3 service marks , plus the owner recently took it to a watchmaker who opened the back and then closed it again as he did not want the job.
Does not take much for lint to get in there.
Hello retro watches, I have an orient tool watch I opened it to see the movement, and foolishly forced stop the balance wheel. Is that bad?
Its def not recommended, depends how you stopped it too, if you pushed downwards on the rim of the wheel, you can easily snap the ultra fine balance staff pivots which are finer than a human hair and extremely fragile. If the balance wheel has suddenly developed lateral play its likely you have done just that.
@@dodgydruid thank you for the answer, only that?
The pivot on the balance staff, nothing more could be damaged? Are there spare parts for that type mechanism? Thank you very much
You will be okay unless you bent it in some way. I often stop them with my fingers by accident when picking them up out of the movement holder.
@@MyRetroWatches thank👍
#462 thumbs uP
Seikomatic-R doesn’t have kanji day wheel?
I can’t answer this. It was not my watch and one the guy who sent it to me bought for his father as a birth year watch. The authenticity of this one would be a mystery given 50+ years old .
I am ironically right now working on another one with an English date wheel .
@@MyRetroWatches I saw other people’s channels and all, so far I’ve seen Seikomatic-Rs are English only. Very interesting as it is 60s JDM model but no kanji. Didn’t expect it.
....talking about oils, do you know what's for the Moebius 8000? It's the only "cheap" Moebius 😂
It’s just non synthetic meaning a watch might need servicing sooner if used. Most of us start out with that oil when we get into the hobby.
Do not use tripods for your work here. Use camera stands. Basically like an IV pole but with locking wheels and an elevator for the camera.
Being a digital photography afair, you measure cameras in grams, not kilograms, so the thing can be rather dainty.
Why a pole vs. tripod? Space and volume of interference.
It is rather obvious.
Good luck!
As I am not using a DSLR it does not matter. I film on a iPhone 12 Pro usually in 4K to give better resolution for when I edit and render to 1080p.
Lost Another One!
Always difficult to listen to one's own advice.
Keep it to watches next time.
I would insist on a watch to never run slow per day. Fix the seiko or replace it.
What sort of comment is this ? I can’t replace a 55 year old movement and given how poor it performed at the start this is a lot better and I’ve done more regulation on it since as I said on the video I would. +/- 10 second a day would be almost Seiko factory defaults.
You talk too much, kind of annoying
