This sporty Croton timepiece features a two-tone dial with white indexes, a magnified date display at three o'clock, and a unidirectional blue bezel for easy timekeeping. The flexible and polished stainless steel band fits securely to the wrist with its fold-over clasp with safety. Japanese automatic movement ensures precision and a water-resistant depth of 100 feet means you never have to worry when you head for the beach. An automatic watch is a mechanical watch that is self-winding. The movement of your wrist and body causes the rotor--a weight attached to an automatic winding mechanism--to wind up the watch. This automatic watch has 21 jewels, which are synthetic ruby stones that the gears turn on to protect the metal parts from grinding together. An automatic watch needs no battery, but it will stop if not worn for over a day (30+ hours) or if you have been physically inactive for an extended period of time. For the times when your automatic watch is not on your wrist, the elegantly-designed watch rotator will provide the movement needed to keep it accurate. A perfect pairing to your automatic watch, this rotator also works as a display case.
