Prospex Seiko Brand 100th Anniversary Limited Edition Marinemaster. Born of perseverance and hope, the history of the Seiko brand name goes back to the aftermath of the devastating Great Kanto Earthquake of 1923, when K. Hattori & Co., determined to rebuild, released its 1924 first Seiko branded wristwatch. Part of a special group of limited editions commemorating this pivotal moment, this landmark timepiece, part of the first globally launched watch series to bear the “Marinemaster” name, is available only in a controlled-production run of 1,000, with the serial number engraved on each case back. Distinguished by its blend of functionality and aesthetics, and featuring the first see-through screwdown caseback on a Seiko diver’s watch, this superbly balanced design also includes an elegantly chamfered case and bezel as well as a flexible double-curved bracelet for a comfortable fit. Based largely on Seiko’s 1965 diver’s watch, the first made in Japan, this exceptional timepiece extends the Prospex tradition of celebrating its rich legacy of innovation in high-intensity timekeeping by re-creating and re-interpreting signature achievements with today’s finest technology and materials. Visible beneath the caseback, the thin, but exceptionally accurate, 26-jewel 6L37 movement beats at a frequency of 28,800 vibrations per hour, and provides a power reserve of approximately 45 hours and manual winding capability. Framed by a uni-directional rotating elapsed timing bezel, the distinctively patterned white dial offers LumiBrite hands and markers. As rugged as it is stylish, this premium diver’s watch, following ISO standards for scuba diving, is crafted of stainless steel with a durable super-hard coating and features a box-shaped sapphire crystal with anti-reflective coating on the inner surface, screwdown crown, and a tri-fold push button release clasp with secure lock and extender.
