·Hi everyone,
I recently acquired what appears to be a vintage Omega with a manually wound Caliber 30 movement, marked “30” under the balance wheel and “15 jewels” on the plate. The watch has a stainless steel case measuring approximately 37–38mm, which I understand is quite large for its era.
The movement, case, and crystal are in excellent shape, and the watch is running well. However, the dial seems to have been redone - possibly by hand in some areas - and the crown is unsigned, though fully functional.
There’s also a number stamped on the movement: 902387. I’m not sure if this is the full serial or a partial one. I’d appreciate any help in:
Thanks in advance!

- Confirming the movement (definitely looks like Cal. 30),
- Dating the watch,
- Understanding any model/reference info from the case,
- And getting a ballpark idea of its value.
Thanks in advance!
