·Hi all,
I just recently purchased a vintage Omega case with both designations: 2494-6 and 2657 that looked in a very good condition. I had both a 351 and a 354 movement with dials that are supposed to fit this case. However, both dials seem and measure too small for this case even though I have seen similar dials on some pictured watches. Both dials measure at 27.5mm but the placement for the dial in the case measures at 28.5mm. Am I missing some kind of a filler ring / inside holder bezel, or my research on the size of the dial was wrong to start with? I can use the help if anyone knows the right answer to this question. Thank you in advance.
