HI Chris

I bet you did not know that  you model is in the "Jumbo" sized case at about 35.5 mm  in comparison to the std 34 mm..  The "Cat Ear" lug case almost always has a caliber 353 under the hood , where as the std case you would normally find a 355 ( swan neck regulator).   I never came across anything that would suggest why but from what i have observed in the field that is the case. hehehehe


Looking forward to seeing you on the forum !

Love the textured dial. Even nicer with that older beveled edge crown (that I've only seen on Constellations). really nice find. This is how Omega lists that watch. Love to know more.

the case being st st and the serial number dates the watch to 1951.

As I understand it, movement serials determine when the movements were made, but watch could have been assembled at a much later date.

Omega assigned series of movement numbers to a calibre.  Depending on the popularity of the calibre, it could be used rapidly or slowly. 

In addition, as Mr Snak observes, the completed movement might be set aside and not used for some time. 

Given the high production of Omega watches in this era, and high demand, it is pretty likely to have been used quickly.  Omega can give you an "Extract of Registers" which will tell you the date the watch was shipped from the factory for CHF 50, as I recall. 

 

Today, Omega uses many different series of movement numbers and does often produce enough they may sit for a couple of years before going in a watch, even with relatively popular calibres.
