Need a chrono part for my 105.012-63. My watchmaker calls it an internal lower pusher. See photo. Anyone know the part number and/or where to source one. Many thanks in advance.

 

Proper name is "pusher stem for chronograph" and this slides onto the operating lever. Part number is 320 1757.

Part is readily available from Omega, so the parts houses should be able to get one for you (if you act quickly).

Cheers, Al

 

Thanks Al

I think the arrow is pointed to the wrong pusher as the zero action is the issue. I presume I need the 320 1758?

 

If that is what you need (for the reset) then yes it's pointing at the wrong pusher. This has been well covered in the recent past...

That's because the watchmaker told the store owner who marked the diagram who sent it to me. Luckily I knew the issue was the reset so I figured it out, with your help today and on prior posts. Thanks.
