The Reactor Heavy Water is the ultimate timepiece for ocean adventures, especially designed to withstand wet conditions. The Heavy Water features high-quality craftsmanship with state-of-the-art materials. A solid, marine-grade 316L stainless steel 40.5-millimeter case features an innovative air-flow design, which keeps your comfortable by allowing moisture to evaporate from under the watch. Water resistant to 200 meters, the Heavy Water, like all Reactor watches, is individually tested to its depth rating. The ultra-durable stainless-steel wrist band includes a triple-secure 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. Durability and function do not trump style here: this watch also features a striking yellow dial with luminous white indexes in elegant geometric shapes; they feature the patented Superluminova finish for up to 8 hours of low-light readability. Arabic numerals are etched onto the stylish, silver rotating timing bezel for additional timekeeping functionality. You'll be sporting elegant style on your next sailing adventure with the Heavy Water on your wrist.
