Part of a rich legacy of innovation in high-intensity timekeeping, Prospex continues to celebrate a long history of sports watch excellence, leading the way with new advances, while recreating and reinterpreting landmark achievements. Inspired by Seiko’s 1965 landmark first diver’s watch, and available exclusively in the U.S. market, this exceptional Special Edition is one of a trio celebrating some of the most demanding diving locations in America and those who dare to explore them. Patterned to evoke the icy surface of the perilous, yet beautiful, Alaska Moulins, the gradated light blue-gray dial features a date calendar and bold LumiBrite hands and markers, and is framed by a dark gray uni-directional rotating elapsed timing bezel. The curved sapphire crystal with anti-reflective coating on the inner surface provides enhanced legibility.

Following ISO standards for scuba diving to depths of up to 200 meters, this exceptional watch offers manual winding capability and includes a 24-jewel automatic movement with a frequency of 21,600 vibrations per hour and a power reserve of approximately 70 hours. 200m Water Resistant
