It's a Genève. Says so right on the dial.
It can't be self winding or it would say "AUTOMATIC" under "OMEGA". (EDIT: I see that's been corrected already)
The exact reference number will start with 136. and can be found on the inside of the case back. The movement will have a serial number which will tell what year it was made. It's from sometime in the late 60's to 70's.
