Prospex 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. Inspired by Seiko’s most iconic diving styles, the case retains the straight contour of the original design with a sharpness enhanced by a sleeker more compact profile. For reliable timing in rough waters, the 23-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. Framed by a deep red uni-directional rotating elapsed timing bezel, the deep red dial features a date calendar and LumiBrite hands and markers. Crafted of stainless steel, this high-intensity timepiece follows ISO standards for scuba diving and is equipped with a secure screwdown crown and caseback and a tri-fold push button release clasp with secure lock and extender. 200m Water Resistant
