Prospex Automatic Diver.
Designed for those who treat life as the ultimate adventure, the Seiko Prospex line follows every challenge with technological excellence and style. With its rugged and powerful design, this distinctive timepiece has been inspired by Seiko's acclaimed 2007 automatic diver's watch, an immediate favorite of collectors drawn to its wide case and the thick printed numerals on its bezel. This powerful reissue, updated in both technology and materials, is crafted of stainless steel, with a sapphire crystal and tri-fold push button release clasp with secure lock and extender.
The black 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. With secure screwdown crown and caseback, this high-intensity watch follows ISO standards for scuba diving. 200m Water Resistant.
