Hello Shawn, welcome to myBulova. It's nice to know that the watch collecting bug has infected yet another! This is a tricky ID, I'm sure that one of my esteemed colleagues will jump in if I get this off a little. The omega date code represents both 1930 and 1940, As Jaroslav points out above it is most likely that your movement is 1940. The case style of your watch is also 1940's but that's where the fun begins. There were two very similar cases in the 1940 as illustrated below, if yours has the engraving shown it's probably an Aviator case. We've dated Aviator watches to the mid 1940's, from 1945 through 1948. Up until 1949 we generally agree that the leading number of the serial designates the production year so my guess is the case is 1946 or 1948. The challenge with that is that a 1940 movement shouldn't necessarily be found in a '46 or '48 case. (The Aviator didn't exist in 1940). Additionally, we have no examples of an Aviator watch with a black dial which makes it a possible refinish. Adding all the potential mismatches (dial, case/movement) we tend to think of these watches as those that do not conform to a known model as Non-Conforming. Understand that a Non-Con designation doesn't take away from the desirability of a watch, you still have a very nice watch, it just means we can't identify it as an exact Bulova model.

Stamford ( without engraving )

I continue to research but am leading toward a Non-Conforming ID

Shawn, any chance of some additional photos? Also is the case engraved? It looks like it is, but I could be wrong.

Panel, Jaroslav and I are leaning to Non Conforming, any other thoughts?
