Trying to identify movement in vintage watch

I am admittedly getting a little granular here, but as the family vintage collection of Omegas is approaching 20, I decided to keep a book with serial numbers and info about movements in each watch. I am hoping to end up with some knowledge to be a better collector! This plain little watch came with a COA and nothing else. The serial numbers on the movement indicate 1939 to me, but do not match what looks to also be a serial number on the case back which shows on the charts as 1944. I don’t see any number that looks like a movement number, only 16 jewels. Does anyone know what movement it is? Is it odd that the case and movement numbers are different? Thanks!

I don't know that movement, but because it is a redial, I think it might be a sort of assembled from parts lying around watch. So not surprising that the movement did not start out in the case.

Correct, dial has been refinished

these had no name at the time, later became the cal 310

movement being nickel confirms a 1st generation example.....mine here shows the correct crown, too

case and serial numbers are not related to each other as to manufacture date.

Why do you think it is a redial? Finish looks pretty old in person. Watch was donated to charity, who provided Certificate.

Thanks! Interesting about the nickel movement. My watch is definitely a ladies watch, it is tiny, slightly smaller than a penny. Is yours that same size? With the case off, mine shows a lot of wear around the edges of the dial.

a mens watch for the time produced......the sizing in mm of the movement is in my last picture.

And, if you wish yours having the correct dial, that is OK with me. Wrong, but OK with me.

Look at the quality of the Omega text and Omega logo.

The reason the case and movement serial numbers do not align is because the case was not made by Omega.
Omega would contract a case maker, Fabrique de Boites de Montres S. Graber SA for example, and provide them with a range of serial numbers for that particular case production run.

With movements, Omega would allocate a block of serial numbers for production runs of specific calibers as they weren't just producing a single caliber at any one time.

The case number usually dates to a bit earlier than the movement.

So you have a "Gents Omega Wrist Watch" dating to 1943, I suspect most parts are original (even the "bowler hat" crown), the hands may be replacements and the dial is an early re-finish. This was often done as part of a service to rectify water damage etc.
