i’ve acquired this bezel but not sure about its type. It appears to be unidirectional and the numbers/dividers and light up shortly in sunlight. The triangles do not. some of the luminous in the letters appears to have crumbled as well, so it might be older? But I'm definitely not an Omega expert! The back leads me to believe it's unidirectional?

Any knowledge from the forum (what reference - 166.???) would be highly appreciated, including an estimated value as a sparepart?

Thanks OF!

 

Here’s a useful reference for the Ploprof 600: https://www.omegaploprof.com/
Could also be a Seamaster 1000 (166.093) bezel, the author of that website also has a site on the 1000.

 

As suggested thats a service bezel for a SM1000 166.093. The serif on the 1 marks it out as a Luminova service replacement.

 

Thank you so much for this information. That resource is really great!

 

Thanks a ton for this information. Any idea on what it holds in value?

 

I think it’s about £200 for a new one.
