The 1960s was a great era for Skin Diving watches, and there were a wealth of designs produced by both major and smaller manufacturers. Benrus was certainly one of the companies that produced several dive models under the name “Ultra Deep” during this period. Amongst the Hugely popular Super Compressor Version, you have the very seldom seen 6502 Reference.

.

The 6502 boasts a 41mm all Steel "Turtle" Case that wears incredibly comfortably and is bigger than its Twin Crowned Brother.  The Dial layout is extremely pleasing to the eye, the Black Dial has a White Crosshair pattern, with "Benrus" and the 3 stars at the top, at the bottom of the Dial you are met by that magical "Ultra Deep" branding.

.

This is an interesting watch, I've only seen a few other examples of this model.
The case is the same as the popular Bulova Snorkel Dive watches, and very similar to the original Doxa SUB 300.
