The Super Rover is a high-end sport watch with a chronograph. What makes it Super and why is it called a Rover? Like other Nixon watches, the Super Rover is built on a platform of water and shock resistancy. It has a raised bezel so the crystal, already made with over 3.3mm thick scratch resistant hardened mineral, is further protected by a ridge of stainless steel. What makes the Super Rover special is the movement and the case construction. The Super Rover has a three sub-dial chronograph movement that measures hours, minutes, seconds and 1/10ths of a second. Just press the upper right button to start and stop, and the lower right button to reset. The case is constructed to a depth rating of 200 meters. It's built with a special screw down crown that forms a mechanical steel-to-steel bond to lock out moisture. (please see instructions on proper use). The Super Rover band is a Nixon-only design: a half polyurethene/half steel link design that puts the steel in the center of the band for strength and the polyurethane on the edges for comfort and flexibility. This reduces hair pinch and hard steel digging into your wrist, but keeps the comfort and feel of flexible linked bracelet. We called it a Rover because it can go anywhere and take anything. The Chrono function makes it Super.
