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 black uni-directional rotating elapsed timing bezel, the black dial features a date calendar and LumiBrite hands and markers. Crafted of stainless steel with black hard coating, paired with a black silicone strap, this high-intensity timepiece follows ISO standards for scuba diving and is equipped with a secure screwdown crown and caseback. 200m Water Resistant
