Im on the hunt for original pushers and I don’t want to make the mistake and hunt for the wrong type. I know there are two types, screw in and press fit.

When my watchmaker opened up the caseback, I asked the question and he said they look to be press fit as he couldn’t see any threads. But based on what I’ve read online, it sounded like HF cases are meant to be screw in. So I’m a little confused on what to go after. Please let me know your thoughts. I’ve attached pictures, not sure if these angles help.

Also, does anyone know the tube diameter for these pushers as well? I know the overall dimensions are 5mm x 3mm.

Thanks in advance.

 

I was looking for the same kind of information as you previously. From this other thread:

https://omegaforums.net/threads/help-me-pls-with-my-105-012.70982/

Dash1 mentioned that all 105.012 use press fit pushers except a few of the last ones where they transitioned to 145.012 cases. Not sure if this helps.

 

I think a little chat with @Archer or @Spacefruit may start you in the right direction.

 

Thanks. Messages have been sent.
