Nice 1970's  Large Gents Amida  Divers Watch, which shouldn't get anywhere near water as it's not even water resistant now ! Still it's a really nice watch on the wrist ! 
The chrome case with a steel screw down back is in very good condition, the dial with Day/ Date function  likewise shows little sign of wear. 
 
Inside the case is a 17 Jewel Swiss Lever Movement 
 
Cosmetically Overall this is in very good condition and running well
