Omega cosmic moonphase
by joseph kal
Omega cosmic moonphase watch has 3 pushers that operate the day, month & moonphase.
Could you please tell me about an omega watch I have. It is the movement and dial only. it runs very well.
The markings on the movement are as follows.
1. Omega 420
2. 17 jewel
3. Serial number # 12691726
4. Omega watch co swiss
I am trying to find out if this is the correct movement for the 1951 square version.
the serial number dates it to 1951. but thats all I can find out.
A watch maker told us this was quite a rare movement and watch itself.
Any help would be much appreciated.
