1965 Diver's Watch Reinterpretation. 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 recreations and reinterpretations of landmark achievements. This versatile 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 timepiece propelled Seiko into the forefront of dive watch design. With contemporary styling and upgraded specifications, this new reinterpretation reflects the look of the 1965 original, but with a sleeker and thinner case designed to fit more comfortably on the wrist. The rich brown dial, framed by a black one-way rotating elapsed timing bezel, includes a date calendar and LumiBrite hands and markers. Upgraded from the original, the 24-jewel automatic movement beats at a frequency of 21,600 vibrations per hour, with a power reserve of approximately 70 hours, and can be wound manually or automatically. Crafted of stainless steel with super-hard coating, this superbly functional timepiece features a dual-curved anti-reflective sapphire crystal, screwdown crown and caseback, and black silicone strap, and follows ISO standards for scuba diving to depths of up to 200 meters. 200m Water Resistant.
