Help to identify this old Omega

[J__D]

I'm not sure if anyone can help, but I'm curious to know what Omega this is, I believe a seamster but I seemingly can't match the exact watch with any, although plenty look similar. I believe it's circa 1940, it was my granddad's watch, and he's passed away recently and it has been given to me as I love watches. I have no interest in selling nor do I even know if it's genuine or what's been changed / updated since the past 70 years, but I'm curious to know what model it is exactly out of curiosity!

You suggest it may be an Omega Seamster - that's a dress watch, I assume.

Have you got a shot of the back?

Attached below, but it has no markings at all it's completely plain, if that helps?

I think it's a seamaster purely from doing some googling, so just an assumption - it's a odd combination of numerous ones I've seen online, but not exact to any individual one I've come across, so it's a little strange!

Looks like it will have a cal 268 movement.

There's a good list here, but they don't have photos of all of them.

The case and hands look like they match this one.

Same case here only in gold, close dial with different hands.
