Hello, this is my first post on this forum. I have an Omega 320 chrono, that is missing the bezel. I intend to have one made. I've been looking on and off for a proper Omega one, but realise I'm not going to find one.

Before I get a bezel made, I'd like to know what was the original size crystal. I have various Omega reference books here, but they don't cover the non-water proof cases.

The case reference is 2463. I know from the serial number it dates from 1957.

Thank you in advance.

 

For case 055ST2463 (Stainless steel):

062PN1094 GLASS PLEXI D31.4 H3.35

Hope this helps.

Cheers, Al

 

Excellent info, thank you. Exactly what I wanted to know.

That would have been me looking for one in 2006, and I have looking for a couple of years before that.
