Help Identifying Vintage 1940s/50s Omega Watch – 18k Gold Mesh Bracelet

As @peterkirk01 noted, it's difficult to say too much from the one photo, but a couple of things jump out at me. Clearly the mesh bracelet is not original to watch because it does not fit properly between the lugs. Also, one can see that the printing is not correct for the era of the watch, which means that the dial was repainted at some point, which is commonly seen for old watches.

If you can provide more information and photos from various angles it is more likely that we will be able to help you. It would be especially helpful if you could have the watch opened, and post clear photos of the movement and the inside of the caseback.

Looks like a re-dialed 2619 to me

Here's one I used to own for comparance
