Omega 26.5 - need some info

Hi all, I'm trying to fit a "wartime" omega into my collection and this one got offered up by a friend of a friend of a friend who collects mostly military timepieces - this one isn't but it's quite interesting.

As far as i know the watch is around 32-33mm in diameter, the dial isn't touched but from my search I've only found one with the same dial and it has "non magnetic" under the Omega writing.
This one also has NO SWISS MADE or SWISS anywhere on the dial - could it be that it was an export model for Sweden or just an omission on this reference # ?

And finally, what's it worth - I know the forum hates these kind of questions but I do not want to rush head first into a wrong watch or a watch i wont be enjoying after a while and not be able to liquidate it to break even...

Thanks!

Sure lol, and you know it that the guy either doesn't have a photo of it or can't open it atm... Always the same story.

Imagine my shock. He just forgot to send it...
