Description

This was purchased as part of special forces unit purchase in the Middle East and was an extra one set stateside.  The CASIO G-SHOCK Frogman GWF-D1000B-1JF is the more desirable Japanese version and is near mint with box and papers.

The CASIO G-SHOCK Frogman GWF-D1000B-1JF is one of Casio’s largest g-shocks, but that is not necessarily a bad thing. Yes it’s large, yes it’s not subtle, but on this watch, it works. Despite its size, it curves and fits the wrist extremely well. It is not too heavy and actually is very comfortable. Casio did a really nice job with the colors and little details on this one.

The first FROGMAN with of ISO-certified 200m (20 BAR) diving water resistance to be equipped with a depth meter.

Feedback from professional divers who perform arduous underwater missions inspired the product engineers to provide superior diving specifications, including reliable sensor measurements during dives to as deep as 80m, outstanding water resistance, and excellent practical utility.

The result is a diver’s watch that helps experts perform to the highest limits of their ability.
