Thanks Mike. After a years of trying to work out how to service a watch Now that I have watched this again and again. I decided to do my own 6139 service on my own watch. If it was not for these videos Mike I would never have got there. My 6309 is now working perfect. All the best Mike and love all your videos.

[@paulambler2613]

Hi Mate, so glad I found this one, been pulling my hair out for a day trying to time the day & date synchronisation on my 6138-3002, I watch both videos because I found them very informative. I've subscribed to your chanel , much better than most, very clear, good footage. I'm like you , just mad about watches, and the bringing back to life of those left for dead timepieces. Well done keep up the good work.

[@MyRetroWatches]

Thanks for your sub Paul. If you find these videos helpful then thats all that matters as this is why I make them . I have a 6139A Pulsations to come to the channel in 2023.

[@1rightrev]

Great--another movement I can now feel a little easier about finding to work on. Thank you Obi Wan!

[@briandrake8719]

Thank you very much for your video. I had a 6139 that "fell apart". With your video I was able to reassemble it and it now runs well!

[@MyRetroWatches]

Hi Brian, thats great news. I do like it when I hear my vidoes have helped someone repair their watch Kind of makes producing these videos (Which is not easy) all worthwhile.

[@cristobalosuna3106]

Thanks for the video! Very instructive, especially telling what kind of oil goes to what part!

[@tonyscott7989]

Top video Mike, I have 3x6139s in pieces at the moment . 2 are half built ,but I will pull them now and start again . Thanks to your efforts making this video I can see what I missed or didn't take enough care with. Kwan has also chipped in with valuable advice, but nothing beats a video in assisting with amateur watch fettling. Thanks Mike, looking forward to the hand setting and getting the hands to zero video. Cheers Tony

[@andre-dx4yw]

good job Mike, watching this as i have stripped and cleaned my 6002, found one broken screw on disassembly other than that its really clean. cheers

[@watchmedraw4340]

I like your idea with the column wheel. When it's done being assembled I would also start and stop the chronograph to move the oil over each face. I know nothing of what I'm talking about but the wheel will stay stationary until it starts and stops.

[@innesireland9253]

Hi Mike, now that other hobbies are on hold i find it nice to expand the watch-hobby in a more technical direction and actually take some apart. I like seiko chrono's from the seventies so your tutorial is very helpful. Thanks!

[@zaygezunt]

That was a lot of work for you - I admire your patience. Thanks for uploading, it was very enjoyable, as always. Take care in these dangerous times!

[@richardtreem1992]

Great video Michael! Definitely gave me some confidence to try servicing one of my own. Thank you!

[@paulsteele6120]

For assembly the gears are pressed together before the shaft is brought to the main assembly. Therefore the shaft in your illustration is capsized and the shaft pressed out. This will of course mean a fixture will have to be manufactured to hold the shaft assembly as the "pinion' is pressed out. The disc spring can then be removed and the two gears can be reined together. The assembly can then be oiled and pressed back together.. This should be able to be done as you live in the industrial Midlands with plenty of short order workshops around. Remember as my old apprentice instructor kept on telling us we have opposed thumbs which allowed us to be the makers in this world.

[@watchtock8818]

Hey there Mark. Loving your vids. Awesome job. I was thinking about the oiling of the chrono wheel. Man, I felt your pain!!......You could use your staking set and use a stake (or even make a suitable stake) that fit over the shoulder and rested onto that gear. That way you could push down square-on and less chance of slipping onto the wheel.

[@neelsengupta662]

Hi Mike, very interesting to watch as I had my 6139 recently restored, stay safe

Great video! I just did my first 6139 last week and you make it look a lot easier than it is! I also broke the chrono wheel on the first try on that exact step trying to oil it hahaha.

[@MyRetroWatches]

Oliver S a was ready to throw in the towel when I broke the chrono wheel. I feel your pain. Good luck with your watches

Great channel, I've watched all of your videos today. I also like to service watches, mostly soviet to that day but after watching your videos i think i'll start looking for some seiko to service :) cheers!

Nice video again mate

[@porkarse5675]

I love old watches, got a seiko 5 which did work but no longer. To get a proper service what would I expect to pay and how would I choose a repairer. I'm aware the watch will probably cost more to repair than buy a used replacement but I like this watch.

[@MyRetroWatches]

great name, depending on what the Seiko model is email me on [e-mail]

[@a.aguilar]

Thank you so much for teaching us to deal with so many great Seiko movements. I would like to find a 6319 at a reasonable price to try and service it.

[@olejohanpalsrud6896]

Great video. I've been vaiting for this one, and it was worth waiting for. I've been wanting to buy a 6139 myself for a bit of time, and now I just have to find one so I can se if I'm able to service one of these. Thanks for a great video.

[@glenntongue7639]

Your videos are the best. I learn a ton. I have a few of the 6139s I have restored and now need nice dials and hands. Any advice?

[@hairyscotsman1417]

Excellent video Mike. 👍 I picked up a Pogue a few months ago, Although it's running well I still want to service it. This video has given me the confidence to see what part goes where. Being 50+ my memory isn't what it used to be, even writing things down & taking photo's doesn't help 🤣 There is 1 other vid of the 6139 done by Dr Watches & Clocks, but it was incomplete with footage missing. I'm sure that this vid will be the blueprint for a lot of hobbyists. Thanks again! 🙌🙌🙌

[@MyRetroWatches]

Hairy Scotsman id love a Pogue, bit of a grail for me with the gold dial.(one day) Hopefully this video can help you. I could not find a decent guide and I think it’s because it’s hard to film. Those springs are a right pain! Dr watches is great fun and a real character. I like the guy.

[@oscillon]

the automatic framework should only go on after the hands are set in place using the proper supporting movement holder. If you don't support the lower jewel for the chron-wheel, you run the risk of pushing it out when you install the second hand.

[@MyRetroWatches]

Daniel Blair this will be in part two. I was just showing how it’s fitted. I have the correct holder to fix the hands from VTA. Thanks

[@oscillon]

[@bangy55]

Love your videos. Especially seeing you overcome heartbreaking setbacks like a broken chrono wheel (been there). I just wanted to let you know there is a step by step repair with photos on a discussion board somewhere on the net on how to repair the exact problem you had here with epoxy. Sorry, but I don't have a link for you. I know, it sounds like a joke, but it actually worked for me. I'm sure you know the feeling of desperation that comes on you when this happens, so if it happens again, I'm sure you can find it out there. You can't really re-stake the wheel because it's stuck between the shoulder and the clutch. Just make sure you get the wheel perfectly flat and in position while the epoxy dries. Good luck!

[@MyRetroWatches]

Thank you Chris. Yes the chrono wheel coming off like that was totally heart breaking. I will have to see if I can find the thread you refer to.i know a few guys who are much more skilled than me who have tried and failed to fix them. Best solution I saw was from a friend who after many attempts has managed to make two bad ones into one good one. They can be disassembled but you do wreck certain parts in the process. Glue sounds crazy but if it works! Time to hit google

[@nagaraja1946]

I enjoy the way of your teachng thanks

[@namenotavailable11]

Thanks Mike. One question - you said you only oil the one pallet fork jewel. Why do you prefer to do just the one?

[@MyRetroWatches]

Jeff hi Jeff.. nice to see your watch running again . So the reason I oil one pallet is because there is a good chance I am over oiling . As the escape passes the jewel each tooth will get lubricated and my theory is some “excess” may then travel to the opposite jewel.

[@timjameswarner]

great content, thanks!

[@valengreymoon5623]

I find it incredible how roughly-finished most movements are when seen under the macro lens.

[@MyRetroWatches]

Valen Greymoon true. Seikos are function over aesthetics

[@valengreymoon5623]

@@MyRetroWatches I've noticed that in my 17 j 6106-7047, but it runs incredibly strong at less than +1/2 second a day.

[@OrjanAa]

Great video! I would suggest manual focus locked on the movement so that it doesn't try to focus on your hands and stuff when you move them into the field of view.

[@MyRetroWatches]

Ørjan Aasegg Johannesen the focus issue is my own stupidity. I usually lock the focus for each bench shot but swapping from microscope to desk each time I oil etc I am so in the moment of filming and doing that I forget to lock ... Must try better!

[@fredrikf2874]

Thanks helped me alot!

[@BATFITTER]

hi nice work and great to watch....i am working on a sieko pouge with the same movement, but the fly back pusher isn't working can you point me in the right direction....cheers in advance

[@MyRetroWatches]

many problems, does the pusher push? often if the movement is not serviced crap builds up behind the pusher and in the case so the pusher does not reach the lever on the movement. The owner then pushes harder, sometimes the pusher then gets caught and then ends up being bent. At that point they would have to be removed ,straightened or replaced. If flyback is just not powerful enough then a service will fix this.

[@spidiq8]

Reckon you deserve to give yourself a big pat on the back for this one considering it's given you a bit of grief and it's not been treated very sympathetically in the past looking at the battle scars. Decent looking tg results too which I'm sure will settle nicely. Well done. 👍

[@MyRetroWatches]

spidiq8 thanks mate. Appreciate your comment from a fellow watch tinkerer

[@davidhammond9336]

Good work Mike, man I really do not like doing the Diashock. When I do it the jewel never stays put and then I do not know if I have replaced the jewel on the oiled side down or not, especially if it decides to escape. I think the micro scope would really help. The diashock spring almost went into the balance eek.

[@MyRetroWatches]

David Hammond you soon learn diashock they are on all Seikos!

[@andersgustavsson8232]

Lost the pillar wheel ring today. Feels great. 👍

[@andersgustavsson8232]

Had to order an entire train wheel with an extra pillar wheel just to get that stupid little ring (I'm more likely to be the stupid one though).

[@sjp8969]

Is there anywhere on the internet that one can obtain some sort of exploded-view drawings of movements ?

[@dodgydruid]

I've just finished a 24hr to the second midnight to midnight on my two 7009's. The 3040 lost 2 secs but the 3100 lost zero seconds, I also done my '75 Citizen and that lost zero seconds whilst my Orient Tri-Star gained 5 secs so the 3100 wins the day pretty much. Its funny I put some of my Vostoks on the night before and my main 090 and 120 Soviet Amphibia's I tweaked over time to perfection actually seemed to lose or gain zero seconds, my Poljot 1980 Olympic also gained or lost nothing but some of my Komandirskies need just a nudge on the advance bar as lost 5-10 secs on average and I am reluctant to nudge them as too far and its too much and a few seconds on a day for an old Soviet watch isn't bad imho. I'm doing my cheap Chinese auto's tonite to see where they are at, a good job noone around to see me as it would have looked like I was doing repetitive rude hand gestures at 'em winding up the autos. Got upcoming vids on Poljot mechanical alarm Signal (very desireable), Chaika Stadium automatic (another grail piece for me with its poison green dial and strident red hands and that evil eye shaped case) a quite rare KVPO (Russian military helicopter) Amphibia and a tidy deep blue dialled Komandirskie Submariner which means I have one of every main dial and case type in the Komandirskie department :) Oh grabbed a job lot of Sekonda (USSR) nurses fob watches with one identical to the one I had as a nurse :)

Where can people find old or broken watches for practice ?

You can get attachments and scopes that allow you to video and some scopes do have a video out, it would make life so much easier for you mate having to work round the camera lol.

[@Jon-xy2gk]

May i ask what lubricants do you use for this assembly? Im a beginner and can't afford to buy so many different types of oil/grease

[@bbowling4979]

Excellent video! Thanks so much for putting these together. They are very interesting and informative. What do you use to clean your watches?

[@MyRetroWatches]

I clean my parts in a watch cleaning machine and sometimes the ultrasonic cleaner if they are really dirty. I have a few videos on cleaning watch parts at home.

[@romanglick]

Brilliant!

[@newlifeforvintagewatches2732]

Hi Mike, for that chronograph wheel you need to buy pairs of livers which are made for this job and working much easier than any tools, I don’t know it’s available in eBay or not? I will send you link as soon as find it anywhere in case you need. Thanks for videos.

[@MyRetroWatches]

New life for Vintage watches thanks . I would be interested in these levers

[@dbzamora]

Very informative video as always Mike. I wish I can work on a chronograph soon. With regard to oiling the chronograph wheel, is it possible to put a drop of oil first then push down on the gear and let the oil creep into the gap so you're not fiddling with two things at once? Stay safe and more success to you! Cheers!

[@MyRetroWatches]

Thanks. In theory yes I would suppose but it’s all about excess oil being left in places you don’t want it

[@oscarlapena8229]

Es usted un profesional buen video ok

[@MrTonymarp]

You mentioned in the video you're adding a link to the service manual but I didn't see the link throughout the video. Can you share the link to the manual here? Thanks!

[@MyRetroWatches]

You will find more than one here on my site. myretrowatches.co.uk/seiko-data-sheets/

[@MrTonymarp]

@@MyRetroWatches Thanks for the link! You have a more extensive collection than seiko’s site. Have you worked on the seiko bullhead, 6138-0040? I needed a small adjustment on mine and noticed some rusting in the chronograph hammer so I decided to do some cleaning. When putting things back, the escape wheel is not fitting in correctly as if the pinion got shorter and not sitting tight between the main plate and the train wheel bridge. I checked the service manual but couldn’t find anything that would help. I know I didn’t break anything and I’m almost positive I did not lose a piece. In short, it’s wobbly causing the movement not to run. Any tip/advise would be greatly appreciated. Regards

[@silvartime]

You are great & profesional

[@Starlord85]

Hi , I don't know if you'll read this , but is there any way I can contact you regarding a repair ? I have noticed you have accumulated alot of experience on seiko 5's . The short of it is , my late Grandads old sieko 5 has a fault. The day wheel (mon,Tues etc) is stuck , but moves intermittently on it's on at random times . I haven't personally opened it up , but I wouldn't know what to do anyway . It's pretty battered and hasn't been used in decades . Everything else seems to work with a shake and seems to keep time well . Might be good for a vid ? Cheers . Phil

[@Supercruze]

Mike, nice work. What kind of numbers did you achieve with this 6139? Honestly, I absolutely love working on these movements and 6138s. They are just so well engineered and I love how they go together. Now that you have done a few 6139s, you need to do a 6138. The calendar side hammer setup for the hour recording wheel is pretty cool. You need to try a 7016 or 7017 chrono next for comparison. Completely different architecture.

[@MyRetroWatches]

Supercruze I’m new to chronos really. Unfortunately I can’t afford them certainly the 6138s . This one was in very poor shape to be fair, very end of the video you see my TG trace. 200+ a bit. I have not regulated yet but can’t see much improvement on that to be honest.

[@Supercruze]

Mike - I will go back and look at the time graph. Most of the 6139s have worn MS arbor ports. I am jeweling these now and something I think you are more than capable of doing. Good content for a future video. Thanks for your channel and videos. John

[@daleyurk4369]

Mike, really nice job. Do you usually use your microscope even when not filming? Wish we could have seen that last bit about verifying that the little pawl was correctly placed. Is it fairly obvious under the scope? At any rate, thanks for making the effort to create this video. Just looked incredibly fiddly!

[@MyRetroWatches]

Dale Yurk I use my scope for oiling and inspecting mainly. The pawl I should have filmed but that bit was filmed on another day and I had not got my scope setup for filming. Under the scope it’s completely obvious as you can see both levers not engaged with the wheel. I could tell when I first wound it , felt too stiff and not the right sound ...

Hi Mike could you advise me on this 6139 it has very low amplitude and running very fast I have changed the mainspring

[@MyRetroWatches]

Low amp and running fast?! Well look at your hairspring as when watches run really fast it will be because Most likely it’s out of shape or coils are touching somewhere to shorten the spring

[@chrishopkins6298]

Thanks i will have a look 😊

[@wgpken]

I've watched this video 12 times. I'm building a 6139-6005, and I just purchased the movement, chrono stops and starts, but won't reset/flyback. Do you have a suggestion on where to look? I am waiting till I get my lubricants and a better movement holder to disassemble, but any tips on my issue would help, thank you.

[@MyRetroWatches]

Fly back you need to look at the hammer. Make sure it’s fitted properly and that you have the hammer spring which is a big long metal part with a hook on it that is attached to the chronograph bridge over the other side of the post that comes up to meet it from the hammer. There is also a spring that wraps around the hammer but that is not the hammer spring. If you are stuck then join the Facebook group in the link in description. Post some photos up and all the members will give you all the help you need

[@wgpken]

@@MyRetroWatches Thank you, I will look at the hammer. The pusher goes and springs back, but it's not engaging the hammer. I'm really nervous about taking my movement apart, it was a lot of money (to me). As you know getting started to work on watches is expensive. I'm not looking to be a watchmaker, just be able to service movements. I do not have a facebook or I would join your group. Thanks again for your time and answering my question.

[@cncdaddio]

is there any watch in particular (cheap, easy to get, not overly complicated) for beginners to start tinkering with?

[@MyRetroWatches]

Martin Ziener I generally recommend Seikos , I started on a 6119 movement and 6309. I have some video series on both as a good guide. Both watch movements were used in many models and you will find them cheaply and easily on eBay
