A waterproof diver's watch for 200m air diving that complies with ISO standards. Although it is large and tough, it features a sophisticated design that has been thought out to the smallest detail. While inheriting the basic elements of M-FORCE released in the past, it has been renewed to incorporate the latest industrial design trends. The basic shape is a round shape that is strong against external pressure, giving it the toughness and robustness of a diver's watch.
