The watch I believe is a front loader ,the diameter is about 29 to 30 mm without the crown, it's about 9 to 10 mm thick.

Thanks

Welcome!

The photos that you've attached are rather blurry, so it is difficult to make an identification for certain. Do you happen to have any clearer pictures of the dial or, ideally, of the watch opened up?

I saw one like this some time ago but can't remember the details.
I think I was discussing with @UncleBuck, does that ring a bell with you Jimbo?

This is the other example we were discussing via PM in 2018.

I've been unable to come up with anything to relate it to an Omega model reference.
The case serial number dates to approximately 1943/1944. The movement serial number dates to approximately 1942/1943. The movement also bears an OXG stamp which means that the movement was imported into the US and cased there which was normal for that era.

Vaguely, my friend.
Going back at least 5 years or more. Seems like the authenticity was being questioned, sorry I can't be of more help!

Hi there, I forgot to tell you that I managed to open the watch , it's indeed a R17.8 SC , thanks for your help .
