Hello all, I would like to ask you expert guys for an advice regarding this bezel. At first I thought it was a Seamaster 300, but I never saw a one like this. To which model it belongs? Any help would be appreciated.

 

120?

 

Thanks.
I'm also inclined to think so, but I can't find a Seamaster 120 bezel with small-size numbers on the scale.

 

what makes you think its omega?

 

Very reasonable question. I think that because this bezel and many other parts were found in an Omega workshop, which was closed more than 30 years ago.
