Reminds me of a Seamaster 200 bezel, ref 166.091, although yours seems to be missing the 9, 10, 11 and 19, 20, 21 etc hash marks.

 

Looks like a big blue bezel. Can't remeber the reference.

 

Definitely not a big blue.
Are you sure its Omega? Or is it also an open question?

 

Seamaster Cosmic 2000 perhaps?

Is an omega and look like a NOS from my watch maker, thought of buying for spare , a.k.a hoarding

 

+1 Omega Seamaster Cosmic 2000
Model ref ST 366.0830 Case ref. 166.0160
Available with GMT or Divers bezel below.


Also on its 'brother' Model ref ST 366.0827 with big crown below.


I realise this is an old thread, but I'm new to the forum and thought I'd contribute regardless.
