Naomi Uemura Commemorative Limited Edition Diver. 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 over 60 years of sports watch excellence with recreations and reinterpretations of landmark achievements. Commemorating daring mountaineer Naomi Uemura, who would have turned 80 this year, this exceptional watch reinterprets the 1970 diver's watch favored by the first man to conquer the highest peaks on five continents. Available in a limited edition of 1,200, with each caseback engraved to show the watch's position in a controlled-production run, this extraordinary timepiece evokes the wonders of Uemura's explorations, with the rich blues of the textured dial, bezel and additional silicone strap suggesting mountain skies, and the mirror polished elements of the bracelet and case reflecting the brilliance of ice and snow. Including a date calendar as well as LumiBrite hands, markers and bezel accents, this landmark timepiece is crafted of stainless steel with super-hard coating, and includes a screwdown crown and caseback, as well as a curved sapphire crystal with anti-reflective coating on the inner surface, blue one-way rotating elapsing timing bezel, and tri-fold push button release clasp with secure lock and extender. As a diver's watch, this special limited edition follows ISO standards for scuba diving to depths of up to 200 meters. Designed for increased torque, the 26-jewel caliber 8L35 automatic movement, assembled expressly for diver's watches at the Shizukuishi Watch Studio, offers a frequency of 28,800 vibrations per hour, a power reserve of approximately 50 hours, and manual or automatic winding. 200m Water Resistant
