With a bold and masculine design, this Immersion diving watch handles the toughest of climates with versatility and ease Men's watch has a 316L marine grade armored stainless steel case Stylish timepiece features a black dial and black thermal polyurethane strap Buckle clasp Japan automatic movement Mineral crystal Water resistant to 200 meters Luminous hands and hour markers Screw down crown Unidirectional elapsed time bezel Case dimensions: 49 mm wide x 13 mm thick Strap dimensions: 28 mm wide x 9 inches long All measurements are approximate and may vary slightly from the listed dimensions. Men's watch bands can be sized to fit 7.5-inch to 8.5-inch wrists. This watch has a screw-down crown (knob) for setting the time. Screw-down crowns create a stronger seal against the case than a push-and-pull knob, giving the watch a greater water resistance factor. To unscrew the crown, grasp the knob and turn it counter-clockwise (towards you) a number of times until it releases. Then pull or push the crown into position to set the time, date, and other functions. To close the crown, press it against the case while turning in a clockwise direction. This watch is powered by automatic movement which means the winding of the spring occurs automatically when the wearer moves his arm. However, it is recommended that you manually wind the watch at least once every two weeks. It is also important to adjust the time once a month as automatic movement can gain or lose a few minutes per month.
