Help Identifying Vintage Omega Cal. 30 - 15 Jewels, 37mm

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:

  • 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!

Unfortunately your watch also has at least a non-original case back. The case front possibly too. The hands dont look quite right either, possibly mis-matched hour/minute hands or a damaged hour hand.

You obviously missed a digit!
It reads 9 042 387, so its of the correct length.
Movement is in nice condition and is indeed cal 30 (no T1 or t2)

But the rest is for the bin:
case is wrong, dial is awfully reprinted
hour and minute hands are wrong

sorry for the bad news

edit: chris was seconds faster than me while I was typing...

I gave him the same news on a different platform, but he was skeptical.

Is it worth restoring it with a proper dial ?

Is it worth restoring it with a proper dial ? And how can i check if the case front is original or not ?

It really doesn't make sense for you to think about replacing parts, restoring, or even spending any more time thinking about this watch. It's too far gone (i.e. there is too little left of the original watch) and there is no plausible way to rescue it. If you like the watch, then wear it as is. Or, you could sell the watch to someone who has a need for the movement, and put the funds towards a better example.

I like the watch, but with that dial is basically unwearable! So i guess selling for parts is the best option.
