Help please..YN55a exploded diagram?

[geoffdragon]

Hello,
Can anyone point me in the right direction of a YN55 exploded diagram, or a reassembly video. I'm having trouble resetting the keyless works...can't figure out quite what goes where..almost got it but not quite...should have taken more disassembly photos!

Thanks in advance
Geoff

Honestly, I don't think you can find YN55 service manual, but YN55 is just a modern modification of very old Japanese orient 46943 movement, you can search 46943 service manual, or videos, or 46 series service manuals like 46D41, 46U40, 46X51....etc. Or search Seiko movement service manual like 7s26, 7s36, or NH35, NH36...etc. They are all very much identical.

If you opened too many watches, you rarely need a service manual for a new watch. Because a mechanical watch is technically a simple device, they are very much similar, typically no more than 100 parts, only 3 to 6 types of oils....., the variations are so limited.

Or you can check Seiko website:

https://www.timemodule.com/

You can find all modern Seiko movement service manuals, like NH35, NH36, NE15,.., NE88..., which covers the simple to the complex.
Again, I want to emphasis, all Japanese movements are very much similar, so you can learn how to assemble.
