Broken Crown Repair: Omega 14791 Cal. 562 Stem 550-1106

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!

Thank you JimInOz !

Crown can be easily saved. The case tube has been pulled out of the watch and is attached to the crown (in red) gently twist it off with some tools this will expose a good part of the broken stem which can also then be removed. With the other part of the stem stuck in the movement you should easily remove it by just removing the movement out of the case, removing the other part of the broken tube in the case and pressing in a new tube with new stem cut to size it’ll be all fixed
