Prospex PADI Special Edition Automatic Diver. Designed for those who treat life as the ultimate adventure the Seiko Prospex line meets every challenge with technological excellence and winning design. This Special Edition celebrates Seiko’s official partnership with PADI the world’s leading scuba diver training operation with the organization’s red and blue colors on its one-way rotating elapsed timing bezel and the PADI logo on the dial. Recalling Seiko’s most iconic diving styles this distinctive watch features a unique case shape with grooved edges resembling teeth. In contrast to its powerful lines the slightly smaller case recalls the landmark designs of the 1960s and ’70s. For reliable timing in rough waters the 24-jewel automatic movement beats at a frequency of 21,600 vibrations per hour with a power reserve of approximately 41 hours and can be wound manually or automatically. The black dial includes a magnified day/date calendar and LumiBrite hands and markers. In stainless steel with secure screw-down crown and case back and tri-fold push button release clasp with secure lock and extender this high-intensity timepiece follows ISO standards for scuba diving. 200m Water Resistant.
