140th Anniversary 1965 Diver's Watch Reinterpretation Limited Edition. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. To mark the 140th anniversary of the founding of Seiko, Prospex is celebrating its rich legacy of innovation in high-intensity timekeeping and the company's role as the preferred watch for explorers under the sea, on land and in the air.

This extraordinary watch, available only in a limited edition of 6,000, 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.

In the signature 140th anniversary blue and white coloration, symbolizing the bright future promised as the sun moves across the sky, the watch features a clean white dial with date calendar and LumiBrite hands and markers, framed by a blue one-way rotating elapsed timing bezel. 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 curved sapphire crystal with anti-reflective coating on the inner surface, screwdown crown and caseback, and tri-fold push button release clasp with secure lock and extender, and follows ISO standards for scuba diving to depths of up to 200 meters. 200m Water Resistant
