Because I shoot macro photos of my watches I noticed that my caliber 321 Seamaster is missing one screw.
Does anyone know the exact part number? I tried to Google it but couldn't find the correct answer.
@Archer perhaps?

 

That's part of the pusher mechanism. Sits under the lever.

 

Yes, and what screw is that exactly?

 

Can you provide a photo from another 321 movement showing what you expect to see there. If you get some better lighting on your movement, it may look the same.

 

Why do you think it's a screw?

 

Part 2352 ? (Screw for pusher stem zero position)

Will check that 2352, thanks!

 

I checked from another photo and clearly is missing and I can see there's a screw hole.

 

OK... this is interesting now. I've checked many photos of Omega 145.006 cal 321 movements. And I think all of them are missing that screw. Every listing on C24.

 

3209 actually - screw for pusher stem for zero action...

It should be there...

 

So, now that I have that screw… can I just screw it in? Or is there more to know?

 

Yes, just install it.
