- Step-by-step disassembly - full service of the Seiko NH36 / Seiko 4R36 movement.
I am using a macro lens and you will see everything in a great detail.
I am generally focusing on the sections that are being disassembled rather than the whole movement.

Wonderful video, very informative. I can't believe Seiko put a plastic driving wheel in there.
I didn't know at the time of making the video but it acts as a fuse. If the day or date is changed at the wrong time and something breaks, it will only be the plastic 👍
The best photography I have ever seen for NH36 service. Thank you.
Glad you enjoyed it!
What a fantastic demonstration of steady handedness and movement understanding. Excellent work
Glad you enjoyed it!
There are many videos about how to service the NH35 movement, but none have such excellent microshots are yours. Congratulations!
Thank you very much. I'm happy to hear you enjoyed it.
@@MacroTime28800 Along with great explanations!
I have a Seiko with exactly this movement. Now I know what's inside. Thank you!
Fantastic!
@@MacroTime28800 I have a 4R35. It is almost exactly the same except for the bits that actuate/control the day wheel, no? I thought these movements had a plastic pallet fork, but I was pleased to see this 4R36 with a metallic and jeweled pallet fork. So that is exciting! (major nerd/geekness)
They are almost the same. I've never seen a plastic pallet fork
@@MacroTime28800 the reason I ask is because I saw this video the other day, and I thought, if Tissot uses a movement like this, surely Seiko at its lower price point, does as well.

Beautiful work.
Thank you!
Excellent quality video, and very well explained, thank you
Glad it was helpful!
I am still learning so this was a great vid for me.
Glad it was helpful!
Releasing power and tension on the main spring should ALWAYS be done before you remove the balance wheel, this should never be removed while it's moving, great way to damage it!!
Thank you for pointing it out, I'll bear it in mind. 👍
how do you release the power?

Thank you for the video!!! Awesome!!!
Glad you liked it! 👍
Nice video good closeup and explanation.
Thank you. How the viewer sees the video on the screen is my top priority. It’s not always possible to show everything the way I would like but I do my best I can.
Skill repair the best👍👍👍
Thank you! 😉
thanks for the insight
My pleasure!
I've been watching your videos ever since... today's morning and I have to admit - they are great, giving my brain something fun to do while I'm performing my job. The only problem is - you're making it too interesting, which makes it hard to concentrate on my tasks at hand, but I'll manage :P
Awesome 👍 I hope you managed to do all your work 😆

VERY GOOD SERVICE VIDAL MUITO BOM TRABALHO VIDAL 👍👍 🇧🇷
Thank you, I'm glad you enjoyed it 👍
Es un calibre cojonudo por mucha evolución que sea del 7s lo an modificado tanto que es una familia nueva ya el meter digamos en la misma base remonte y akin parada es una modificación sería y como siempre Seiko es único el sistema de parada haking es de lo mejor que e visto no e visto otros parecidos
👍
I enjoyed that, sad to see the quality has dropped a fair bit with Seiko if you consider the much higher quality levels of the 7009/6309, have yet to own a NHxx powered watch as I thought I got one in my recent acquisition of a new Lorus automatic and it turns out to be a 7S26C inside. Am this weekend attempting my first 7009 rebuild, have done two Soviet Slava's and both working superbly so now to wade in deep into the world of repairing 'em :D
Glad to hear you enjoyed it, I enjoyed making it. I know, the quality is not what it used to be, just like everything else. Have fun with the 7009!
No dial protector when removing the c clip? Brave man!
I'll use it next time!
Tenemos calibres vintage Seiko de tres saetas que son más complicados que un cronógrafo debido a la disposición de las piezas Seiko se conoce por el cuarzo pero en mecánicos siempre a estado hay uvo un periodo de los 80 al 2000 que no hicieron mucho mecánico pero en un momento sacaron toda una nueva colección casados en antiguos calibres estos yamados antiguos calibres en su momento ya se decía que estaban muy evolucionados y hoy por hoy pueden entrar como calibres actuales
For the money the NH36 costs it is unbeatable. In my latest video I service Seiko 7005 movement and the Delta after the service is 18 seconds, 53 years old movement 👍
Great Leo. As always, an ideal video as a tutorial. I am going to disassemble and service my Seiko 4r36 with some fear and after watching your video twice. Until now I have always made Eta and some Vostok. But I have never dared with Seiko, watching the videos they seem more difficult to me. Allow me a question, in your opinion is a Seiko more difficult than an Eta? Or if I have made Eta I will have no problems with a Seiko. After this 4r I will go for a 6r that I have also seen that you have a video. Thank you.
It isn’t difficult at all. I think you probably feel a little uneasy because you’ve not done one before but once you’ve done one, you’ll realise that there’s nothing to worry about. You could always train on a cheap NH36 before you do the 4R 👍
@@MacroTime28800 Thanks Leo. It's a good idea to train with an NH36. I have some Seiko that, although they work well, have values of 1.0 ms error and 220-230 amplitude, including some 6r15. Right now I have just completely restored an ETA 2551 from 1968, which is very very small, and has run at +6 seconds per day...now I'm going to go for the Seiko. Thanks Leo.
Mine came not working on shipping...the balance wheel not move yet has tension on clock spring it all wound up...what do u think
Personally, if it’s brand new, I’d ask for a replacement. If you bought it to practice on, start with a movement that works well and see whether you can take it apart, put it together and everything works well. If you got a movement/watch for a repair or service that would be different but a new movement, I’d get a replacement.
Thanks for sharing this! Does the 4r36 also have the same plastic cog wheels as the ones found in this NH36? Just curious if there’s any difference between the two movements or if they are in fact identical in terms of parts. Thanks!
I've never worked on one but must likely they are the same. I've done 6R15 video, the Alpinist that that also has plastic. It acts as a 'fuse'. If you change the date or day at the wrong time when you shouldn't do it, it's the plastic that will break, not the other parts they interract with.
@@MacroTime28800 thanks, i did not know that. Makes perfect sense!
👍👍 🇧🇷
👍🇬🇧
Nice video! Is there any big difference beetwen branded seiko and unbranded nh movts? I mean material quality first. I have a nh36 (built in a skx) with the 6r20's 28.800bph escapement system for 3 years. Accurate as the hell. I hope it will be reliable nh36. How often need service the escapement system?
I don’t think there is much difference between them. I have 6R24B here that looks very much the same as far as the materials go. The finishing is nicer on the 6R24B, you can see that on the bevelled edges but only under strong magnification.
In my opinion, I would say get it serviced every five years or when the time keeping starts degrading, whichever comes first. Every watchmaker will have a different opinion how often to service watches, I’m comfortable servicing my watches every five years.
@@MacroTime28800 i was wondering, based on the current quality, is it still worth buying a seiko?
I don’t see any reason why not. They may have plastic parts inside them but even the old movements with plastic parts are fine. I have a few modern Seiko watches myself and I don’t have any issues with them. If there is a Seiko you like, go for it.
@@MacroTime28800 wow okay ,thanks! I was thinking of buying a model with easy to read watch face 4r36 movement xD
Nothing wrong with the 4r36 👍
Does the movement come with minimal lubrication from the factory? Or does the watchmaker use a better quality set of lubricants? To achieve more accuracy?
Better quality, perhaps. There are never ending arguments which lubricants are the best lubricants.
If you buy a movement, any movement, or a watch, the mechanism wouldn’t have been in motion for months, perhaps even years. The fresh lubricants will make a difference.
@@MacroTime28800 thanks for the reply 👍🏻
Hi Leo, where can i get a black stainless steel bracelet, for my srp311k1 ?
Thx.
I don’t know much about bracelets I’m afraid. I know “Strapcode” sell aftermarket bracelets for Seiko watches but I’m not sure whether they have one for your watch.
Check Strapcode out and if they don’t have it, I would suggest joining a watch forum where you may get an answer.
I liked your video. May I know what kind of Watch Movement Holder you used? Then, where can I buy it. Thanks
Thank you!
It’s the Bergeon 4040P. If you Google ‘Bergeon 4040P’ you will find one.
@@MacroTime28800 you are a big help. Greetings from Philippines! 💪
I wasn’t sure where you were from that’s why I didn’t give you a direct link. It wouldn’t have been much of a help as I’m in the UK.
I’m glad I was able to help 👍
Loved the content. But have to ask, How do you sound so Scandinavian and Manc at the same time 😂 ?
From Czech and not far from Manchester 👍
lot of plastic parts in the movement, do you think that will affect the long term life of the movement ?
Hard to say. I have certainly seen broken metal parts in movements, setting lever springs etc. so we can’t say metal is 100% perfect. The plastic is not pretty, I’d also prefer the plastic not to be there but I think it will last for quite some time. If you are thinking of buying a Seiko that has plastic parts, I wouldn’t worry about it. Rolex caliber 3035 has plastic bushing in the minute pinion, it’s not just Seiko who’s guilty of plastic.
When you think about it, those gears are used for the day date change, so they are low usage. ETA's Powermatic 80 movement uses plastic for the escape wheel and pallet fork and get away with it.
Teacher，please tell me what camera and lens do u use in the video，thanks👍
It’s in the description, I say that in the video
Getting the mainspring barrel open without damaging the gears or the exterior was impossible for me. Next time I'm just replacing the complete barrel assembly, as Seiko recommends.
You can't beat a brand new barrel complete 👍
La grupa del calendario semanal se saca con una pinza empujando al igual que la que sujeta la kevel magic
👍
Is it true that this movement has the shock protection on the train wheels too?
There are a couple of capped jewels with springs but they are not in a chaton and if I remember correctly they are only one side.
@@MacroTime28800 still very impressed especially in this price range
It is a bargain and Seiko make their own movements opposed to many Swiss manufactures who will use ETA movements.
Now a days the complete balance is available......?
Probably. I've not looked. The movements are so inexpensive that I buy the complete movements rather than spending time searching for the parts.
Luego esque como no va a gustar Seiko
Es una pasada desde los calibres vintage comtrullen los relojes que no tienen nada que ver con la construcción suiza ni alemana sus propios materiales en espirales volantes muelles e un punto y aparte
👍
Do you know if 4R35 and 4R36 movements have plastic parts?
Most likely, the 6R15 which is one level above the 4R movements has plastic parts
@@MacroTime28800 Thank you Leo for your answer. Is it possible to have your email so I can ask you more questions about Seiko's movements?
@@capreyvideo Unfortunately I do not have the time for it.
I would suggest joining one of the watch forums: www.watchrepairtalk.com/
Ok
Can you do these videos for the 4r34
Perhaps at some point in the future, I have different projects lined up at this moment.
By following along with u... I did it. And it still works. Wow. Though the C clip was bi**h to return to its place. That was really my only snag. And I may have been a little rich on the lube. tnx. That was fun.
Glad it helped! 👍
Ok a cosa que se critica por su bajo coste bajo coste para Seiko debido a lo que es Seiko si este calibre lo uviese sacado otra casa suiza seguro que todo serían alagos luego es un calibre base que Seiko tiene un catálogo impresionante yo era al principio reticente pero hoy por hoy los NH y 4r son calibres a la altura de cualquier calibre denominado de batalla osea fiable y duradero
👍
Que no notas nada con los tornillos
Los tornillos de Seiko son más digamos difíciles de quitar que los eta e y otros tienen una boca muy fina y se escapa el destornilafor
👍
