Omega De Ville 166.1108 (Cal. 1108) - Need movement clamp

Hi everyone,

I’m restoring an Omega De Ville Prestige Ref. 166.1108 with Calibre 1108 and I’m trying to identify the correct Omega movement clamp and clamp screw part numbers.

The watch is original with:

• Reference: 166.1108
• Calibre: 1108
• Stainless steel case
• Original case and movement

One movement clamp is present and appears original, but the opposite clamp and screw are missing.

I’ve attached photos of:

• the movement in the case,
• a close-up of the existing clamp,
• and the inside of the caseback.

I’m hoping someone with access to the Omega ESPC/case parts catalogue could tell me:

1. The Omega part number for the movement clamp.
2. The Omega part number for the clamp screw.
3. Whether both clamps are identical on this case.

From comparing with other Omega references, I believe this is a finger-style clamp secured with a single slotted case screw, but I haven’t been able to find the official part numbers in the public parts lists.


Many thanks for any help.

Clamp - 1060115
Screw - 1072984

Both are the same on each side.

Thanks
