Broken crown - Omega 14791 Calibre 562

Hello everyone,

I’m currently working on my vintage Omega reference 14791 fitted with a calibre 562.

The crown came off, and after inspecting it I believe the winding stem broke and a piece of it is still stuck inside the crown.

The watch is still running: since it’s an automatic movement, if I get it going and set it to the correct time it will keep running on the wrist. However, without a crown it’s obviously not very practical to use and the movement is not very protected..

Ideally I would like to:

• remove the broken piece of stem from the crown
• buy a new stem (ref. 550-1106)
• and reuse the original crown if possible.

Here is what I can see so far:

• the crown looks fine from the outside
• there is a small metal piece visible in the center (likely the threaded end of the stem)
• the movement itself looks clean, just a bit of rust.

My questions are:

1. Do you think it is realistic to extract the broken stem piece from the crown?
2. Is there a recommended method ?
3. Is 550-1106 indeed the correct stem reference for the calibre 562?
4. If the crown cannot be saved, does anyone know the correct crown reference for a case 14791?

I’ve attached a few photos of the crown and the movement.

Thanks a lot for any advice!
