The Reactor Heavy Water world tide watch is the ultimate timepiece for ocean adventures. This digital men’s watch features 30 preset tide chart locations, with room for up to five programmable locations; it also features an air and water temperature sensor, dual time, a 1/100-second chronograph, and multiple other timers and alarms. All of these functions are displayed on the easy-to-read, silver digital dial; a uni-directional rotating timing bezel, which features handsomely etched Arabic numerals, also provides additional timekeeping capabilities and adds a stylish touch to the watch face. On top of its cutting-edge technological capabilities, the Heavy Water features high-quality craftsmanship with state-of-the-art materials. A solid, marine-grade 316L stainless steel 45-millimeter case features an innovative air-flow design, which keeps your comfortable by allowing moisture to evaporate from under the watch. The ultra-durable stainless-steel wrist band includes a buckle clasp for extra security. The watch also features a secure “screw bar” case-to-band interface, which provides five to seven times the strength of traditional spring bars; and the hardened mineral glass crystal offers extreme scratch and shatter resistance. Water resistant to 200 meters, the Heavy Water, like all Reactor watches, is individually tested to its depth rating.
