Prospex 1965 Heritage Diver's Watch

1965 Heritage Diver’s Watch. Designed for those who treat life as the ultimate adventure, the Seiko Prospex collection 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 more power, greater water resistance, enhanced legibility and a compact construction designed for maximum comfort, this rugged yet sleek timepiece reimagines Seiko’s 1965 first diver’s watch, the beginning of the company’s legacy of setting the standards in dive watch technology and design. Framed by a coordinating uni-directional rotating elapsed timing bezel, the rich black dial offers a date calendar between 4 and 5 o’clock allowing for LumiBrite coating on the hands and all 12 markers, improving symmetry and legibility. With an upgraded power reserve of approximately 72 hours, 3 full days, the 24-jewel automatic movement beats at a frequency of 21,600 vibrations per hour and includes manual winding capability. Crafted of stainless steel with super-hard coating, this superbly functional diver’s watch features a curved sapphire crystal with anti-reflective coating on the inner surface, as well as a screwdown crown and caseback. The bracelet is designed to incorporate links with a short pitch and a smaller clasp to match the sophisticated case design, which despite its slim profile, follows ISO standards for scuba diving to depths of up to 300 meters. 300m Water Resistant.
