[@debabratadey7407]

thanks for taking time and making the video! I am from India and started my journey of watch service as a hobby of mine. I have couple of automatic watch and one of them is Seiko 7S36 movement. I think it is similar to this movement. and this video really helped me and given courage to open my watch and try to service it. thanks again..

[@WeekendWatchRepair]

That’s great, glad to hear you’re diving into watch repair.

[@johnvaluk1401]

Thank you for another great video. I’m glad you liked the 5k idea. Vintage Seiko would be nice ie. pogue, bullhead, diver, GS or even a lord matic. Just to suggest a few. But honestly what ever you decide would be more than generous. Oh yeah loved the dial of this watch! Thanks again!

[@WeekendWatchRepair]

We will come up with something good. I appreciate the suggestion for a 5K giveaway.

[@WatchWithMike]

Nicely done! Great camera work and explanations. I've been mostly working on Swiss watches, so seeing the Japanese approach is refreshing. I like how Seiko builds the return springs into the parts, instead of using thin bits of bent wire.

[@WeekendWatchRepair]

Much appreciated! I like how they do that as well. They are built to be robust and reliable, and it appears they use that thought process in their engineering. It's quite smart to combine the springs into the parts, especially from a mass production standpoint. It's just a different philosophy in watch manufacturing. I do enjoy working on Swiss movements as well. You can certainly see the different engineering concepts between the two when working on them. Both are great in my opinion though.

[@WatchWithMike]

@@WeekendWatchRepair agreed!

[@Hamlock_Maneuver]

I love that watch face!

Thanks for watching!

[@Mars-zgblbl]

Thanks a bunch for this video!! It will help with servicing my yard sale 6106. I previously broke pivots on two pallets from other watches 😢, so appreciate seeing things done right. Watching the technique in this video, it looks like the correct approach is to incrementally and alternately lift the plate off the posts, and keep the bridge parallel to the main plate as close as practicable. Also align the screwdriver towards posts or screws while levering so if it slips, it stops at the screw or post. Is this correct?

[@WeekendWatchRepair]

That's how I like to do it. Many movements have slots that are designed to be used to lever the plate off. Doing it incrementally is the key though.

Superb job, I love my vintage Seiko's and my 19 jewel 7006 has a similar problem with the hands but mine are very loose when turned with the crown also the minuet hand just stops moving even though the watch is still ticking so thanks for the work and commentary shown here to give me some tips on how to maybe sort it out. Cheers Weekend watch repair

[@WeekendWatchRepair]

Thanks for the comment. The first thing I thought of when you talked about your watch is a loose cannon pinon. You might want to give that a look. Those can be tightened up with proper tooling. Replacements can also be found relatively easily.

[@jeffreydheere4737]

On your question about the editing. I find it more valuable to have the whole movement visible while parts are removed instead of zooming in on the screw. The point being it's easier to see exactly where a part came from, where it goes and in what order.

[@billyleblanc5930]

I enjoy your views very much closeups are great

[@WeekendWatchRepair]

Thank you very much.

[@_f355]

I know this is an old video and you might already know this, but when you turn the hands backwards at 10:32, the seconds hand is moving because the balance is out - the pallet fork is allowing the escape wheel and the entire train to move backwards. It's a really good way to get a chip on the pallet stones, so it's better to not do that too much!

[@ForestWoodworks]

Adam, can you recommend a crown gasket assortment, as well as a case back assortment, or what I'm looking for in purchasing those? I just don't know enough yet to know I'm not wasting my money. I'm so close to opening up a movement and having a whirl, but don't quite have the courage. In the meantime I've just been doing peripheral tasks to get comfortable, eg, cleaning case and bracelet, installing crystals (breaking crystals 😂), installing stems, installing hands,driving my wife crazy with tool purchases, etc. 🎉

[@WeekendWatchRepair]

I’ve got mine from CousinsUK. For caseback gaskets, I’ve got assortments for flat and round gaskets. Regarding crown gaskets, a standard assortment, and a D & E shape micro assortment specifically for Japanese movements.

[@ForestWoodworks]

Thank you, Adam! I will proceed with this info. Just so you know, after this comment yesterday I said "What the heck, I can't keep avoiding it" and dove into my first service. Citizen 8200 from a Franken watch I got myself for Christmas... it stopped working 30 minutes after I got it. 😂 Weird symptoms, like the hands spinning out until the power was gone. When I opened it yesterday, two things jumped out: a pallet bridge screw was loose and there were small metal shards everywhere throughout the movement. I'm hoping nothing critical damaged tho. Got everything cleaned up using my ultrasonic today, and it's ready to start the reassembly in the morning. Even if it doesn't work, it's still a learning experience. Thanks to you sir for plowing ahead and inspiring us!!

[@WeekendWatchRepair]

@@ForestWoodworks That's excellent to hear. Did you find out where those metal shards came from?

[@ForestWoodworks]

​@@WeekendWatchRepairI got it! I got it!! Been working on it since I commented the other night, just finished and it's running! My first automatic watch service fix. 🎉 The whole movement was dirty, so I think the shards came from whatever environment it was in before. Although I was laughing because when I went to oil the balance jewel and pulled off the cap jewel, there was a perfect dot of oil just like you teach. The whole movement was filthy, but someone took the time to oil the jewel properly😂. I can't believe I got it to work. A complete service, rudimentary but complete. Only thing I can't do to it is the adjustment on the timegrapher and I also don't have expertise to dial in the hairspring. Also of the whole job, I probably spent a total of 3 hours on my hands and knees looking for parts, cleaned my office 4 times too😂. I really can't believe this. So stoked!!

[@WeekendWatchRepair]

@@ForestWoodworksThat's fantastic. Congrats!

[@SlayerMtg]

Funny u mentioned OCD flaring up with magnification! I got my first microscope this Christmas and mine has been on overload!

[@tylerfukuda]

Maybe I missed it but can you provide what oils/grease you used and where you used them? Thank you so much, your videos are invaluable!

[@WeekendWatchRepair]

Thank you for the kind words. The lubrication on this movement was as follows: Moebius 9010 on the balance jewels, escape wheel, fourth wheel, and other fast moving lighter friction spots. 9501 grease on parts of the keyless works & cannon pinion, 9415 on the escapement, Seiko S4 grease on the barrel walls and pawl lever/first reduction wheel junction, 8200 on the mainspring, and HP1300 everywhere else. All gaskets got silicon grease.

[@mapled3135]

[@WeekendWatchRepair]

[@Hamlock_Maneuver]

Try using a humidifier to control the dust. I use these when I'm installing screen protectors. Absolutely zero dust at all.

[@WeekendWatchRepair]

Interesting idea. I appreciate it.

[@jakelewis3d]

A bold venture into hairspring manipulation! But your goal of maintaining an even gap between outer coil and terminal curve is misplaced - the coil is a spiral - i.e. has constantly INCREASING radius, whereas the terminal curve must have a FIXED radius - exactly equal to the distance of the midpoint of the regulating pins from the pivot center. Thus, they can not be parallel - the separation under the stud will be less than the separation under the dogs-leg - (as it was when you found it). The key test for this is that the hairspring centering you depict at 8.47 should maintain across all positions of the regulating arm (or at least a reduced arc of the likely positions). This can only happen when the terminal curve is of fixed radius.

[@michaelbelice2024]

I really appreciate your attenton to detail, really good videos and nice narration. I do have a qusestion though, where do you get all your seiko parts from? Gaskets, crystals,etc..

[@WeekendWatchRepair]

Thank you Michael. I have a pretty good collection of Seiko parts and gaskets in my stock at this point, however if it is something I don't have I can generally find parts on eBay or one of a couple websites for parts on specific Seiko models. Most of the time though, eBay is the easiest place to find the parts I need.

[@jeff1176]

I wonder if its a frankenwatch from India being from ebay. The cannonpinion being that tight and the movement of the hands leads me to wonder the history of the watch. Are cannonpinions interchangeable? It does have a beautiful dial. I have one 7000 series and a 1st gen orient both are non manual wind watches. I'm not a fan for that reason. Both are great watches, the purist in me says if they have a crown it should wind the watch. Probably why i dont like quartz watches too. Lol. Great video, close ups and all are great. Your production value is as good as any other watch makers on you tube. Keep up the great work.

[@WeekendWatchRepair]

I appreciate the kind words. Cannon pinions can be interchangeable between certain models & cases (due to required height). I don't believe this was a frankenwatch. My understanding is that it was bought in a lot of a few watches from a private individual on eBay. Outside of the cannon pinon issues, this watch did not appear to be pieced together from multiple movements. It was in pretty good shape for the most part. My thought is that it had just been a very long time since it's been serviced (if ever), and once it became heavily magnetized it was put in a drawer and forgotten about until it was sold. I could be wrong, however I think it turned out well though.

[@jeff1176]

@weekendWatchRepair it turned out very nicely. I really had no idea if cannonpinion's could interchange.

[@nujanep7354]

Your voice sounds like Marshal from Wristwatch Revival 😂 anyway , like your repair

[@WeekendWatchRepair]

I've heard that a few times now, and to be completely honest I do not hear any similarities at all, haha! I suppose everyone hears their own voice differently than others hear it. I just got a cheap microphone plugged into my computer. Not running my voice through any type of audio equipment or programs (perhaps I should look into that - lol). I appreciate your comment though. I'm glad you enjoyed the video.

[@MechanicII]

What do you use to clean the pivots? It looks like an eraser in a pin vise. I assume the pivot pokes goes into it, like poking an oiler into pith, and then just twist. Or is something else going on?

[@WeekendWatchRepair]

They are silicon polishing pins. EVE is the name brand, but you can buy generics that are the exact same thing. Esslinger has a set - ref. SKU 10.01339 - I use the green 'extra fine' tips. You push the pivots (gently) into them and you can clean and lightly polish the wheel pivots. It's an easy method to use as longs as the pivots are not in too bad of shape where they would require a jacot tool (which is something I want to show in the channel at some point). I hope that helps.

[@anthonycaryl1079]

I've just got a Seiko 7S26 doing exactly the same thing with the second/minute hands, wonder if it's a dried up seiko grease thing? Hope mine behaves as well when i attempt the service

[@WeekendWatchRepair]

Thanks for watching. Those are pretty straight forward movements. Hopefully you'll get it sorted out. Best of luck.

[@Blackeye35]

Hi! When you replace the caseback gaskets are you using a generic one or a seiko replacement? Do you mind sharing your source? Thank you, love the videos!

[@WeekendWatchRepair]

It just depends on the particular case. I have an assortment of flat gaskets (bought from CousinsUK) that I pull from to service many of the Japanese style watches I work on. Most of the time I can find one of the correct size and thickness. Sometimes though I have to source an OEM gasket.

Hi again, I probably missed this part but are there seals on the 2 chronograph shafts . And because it 50 years old they are probably dry. Is that what would make them almost impossible to spring back ? If so if I remove them and use a “little “silicone would that help them move. The watch for sure won’t be ever in the water. When I’m watching your videos it’s hard to remember how small things are. You do great narration. Thanks for your help. It’s just what I was looking for.
