Prospex U.S. Special Edition. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. 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 re-creating and re-interpreting landmark achievements. Inspired by Seiko’s 1965 landmark first diver’s watch, 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. Crafted of stainless steel with scratch resistant super-hard coating, this rugged and stylish timepiece also includes a screwdown crown and caseback, and a tri-fold push button release clasp with secure lock and extender. 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.
