Hi.
That's not the most popular Omega ref. - I suppose it's from 198X?
Price wouldn't be high anyhow, due to case condition (it's hard to say for sure, but based on the attached pictures it has a wear-out on lugs?). If case not in a good shape you have no point to invest in this wristwatch ( from commercial point o fiew).
If you want to spend your time/money on it: It's good as first to find-out if movement is in running condition (change battery) and if it starts, you'll could change the glass (correct one is: 063PX5131)..
Good luck!
