Hello all,
My grandpa bought this Omega watch about 20-25 years ago. Unfortunately he can't find the certificate of authenticity anymore but I'm trying to help him to find out what exact model it is. He doesn't want to sell it, he just wants to know the exact model. I have been trying to find the watch on the internet for a long time, but unfortunately I had no success. Do any of you have any idea what model this is?
Thanks a lot!

The answer will be on the inside of the caseback.

Unless you have the exact tool you need, don’t try to open the watch. Improvising will almost certainly damage it.

TBH, it seems like a lot of trouble for nothing. Why exactly does grandpa need the reference number?

Sure. Grandpa needs to know the reference number, because he's not going to sell it.
