Looks to be in good condition. The gold plating on these models is very thick, which makes any scratches you'd get from wearing it much less noticeable.
Hopefully the movement still works. As others have said, you'll want to remove the back, remove the old battery, and replace it with a 344 cell (available online for ~$2). Unfortunately, if the movement is not working, it would be very hard to fix; servicing these watches is next to impossible.
Good luck!
