Seamaster 166.027 Movement Ring

yellowhammer · Aug 19, 2025

I’m restoring a Seamaster 120 but having trouble finding a movement ring for the case. Can someone point me in the right direction before I dust off the 3D printer and waste hours creating one I’ll have to undoubtedly fiddle with anyway?

I needed a movement ring for an SM120 around ten years ago. After trying several watchmakers I was told that the part was practically impossible to find on the open market but that Omega still had it.

I sent the watch to STS for repair and they sources the part from Omega.

I can’t imagine they’ve got any easier to find in the last ten years so you’ll need a watchmaker with an Omega parts account
