Seiko's latest NH35A movement disassembly

:2021-12-22:3373:

Hello everyone! I’m a cute new one. I haven’t been in contact with watches for a long time. Now I’m studying watch repair with my dad. My dad will disassemble some movements for me from time to time. The watch parts company bought it for accessories, and I took it apart to learn. In order to facilitate future consolidation and study, I took photos of each dismantling look with my mobile phone. Compared with the standard machine, there are many more parts, so I can't name many of the parts that have been removed. I hope you don't mind. Below are the pictures I took with the fruit machine, you will take a look.

The first is the back. There is SII on the automatic rotor, and the movement sold by Tianmadu is marked with SII.

The slot in the middle of the rotor is very long (you can see it in the first picture).

Then, be careful when disassembling the splint, balance wheel and hairspring.

Then to the horse (pallet fork) and the fork splint.

Then to something that I don't know what it is called.

The big steel wheel, there is another wheel with an unknown name, and the big steel wheel screws are also relatively large.

This should be the upper splint.

The other side of the upper splint.

A wheel on the upper splint also has a strange-looking part.

Barrel wheel, second wheel, passing wheel, escape wheel.

It should be a middle splint. It's all done here, and the minute wheel on the side of the calendar can't be removed without the center wheel.

Now start to dismantle the calendar side.

The last is a family portrait with all the parts. This movement has been completely dismantled here, and I will dismantle some movement I haven't seen from time to time to show you all. Thank you for your support. If you don’t understand the watch, you can leave a message and ask me, I can ask my dad to help you answer.
