Help identifying this vintage watch?

Hello everyone, I received this watch from my father today. It belonged to my grandfather, and he has passed away more than 30 years ago. It's been tucked away for decades, but soon as I picked it up thing began ticking again and seems to be keeping good time.

I was hoping someone could tell me more about it and am glad to come across this forum. Can someone help identify this watch? It looks like a Geneve or a De Ville but all the pictures I see online, those watches have a script going across the dial - unlike this one.

The crystal appears to be made of plexiglass/ hesalite and has a few scratches, and the case back appears to be screw down. The strap looks original, and has an Omega engraving on the inside. I think the case might be gold or gold plated. I noticed a very tiny script of 20 with the Omega logo on the case between the lugs.

Any information would be appreciated, thank you in advance.

Looks like, perhaps, a Pulsar clasp cover. The magic numbers of knowledge are on the inside of the caseback. Without that, you don't get much, if at all.

Hello Calvin, To get the information you desire, the best way is to have a watchmaker open the watch. This will reveal the reference number (model) of the watch. Also you will find more information on the movement. The serial number will give you an indication of the age and an additional number will give you the caliber of the movement.
It appears you have a watch from the seventies, possibly gold filled. The band is a combo of pulsar and Omega parts.

Got it, thanks guys!

Will do, thanks!
