1965 Heritage Diver’s Watch. 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 with re-creations and re-interpretations of landmark achievements. Updated with today’s technology and materials, and a sleeker and thinner profile, this rugged timepiece reimagines Seiko’s 1965 first diver’s watch, an automatic timepiece with a then exceptional water resistance of 150 meters. Offering an extraordinarily legible dial and durable enough to become standard equipment on the Japanese Antarctic Research Expedition (JARE), this landmark watch propelled Seiko into the forefront of dive watch design. This re-interpretation features another advance, with a special high-intensity fabric strap, made in Japan with superior flexibility, but the strength necessary for diving. A beige fabric alternate is included with the brown fabric primary strap. The rich brown dial offers a date calendar and LumiBrite hands and markers, framed by a black uni-directional rotating elapsed timing bezel. With a power reserve of approximately 70 hours, the 24-jewel automatic movement beats at a frequency of 21,600 vibrations per hour, and provides manual winding capability. Crafted of stainless steel with super-hard coating, this superbly functional timepiece features a curved sapphire crystal with anti-reflective coating on the inner surface, and a screwdown crown and caseback, and follows ISO standards for scuba diving to depths of up to 200 meters. 200m Water Resistant
