This is a Gents Orvin Divers Watch from either the late 60's or early 1970's, it is without its  rotating bezel, but it's a really nice watch even without it !
The Watch is in good condition. The case is in steel with one or two small dents and a number of superficial scratches, the dial shows very little wear and is clear and visible.

Inside the case is a Swiss 17 Jewel movement 
 
 
Cosmetically overall this is in good condition and running well.
