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, this distinctive watch includes such upgrades as a black ceramic one-way rotating elapsed timing bezel, magnified date window and sapphire crystal with anti-reflective coating on the inner surface. The white dial, with LumiBrite hands and markers, has a 3-D pattern reflecting the shape of the black and gray bezel edge. For reliable underwater timekeeping, 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.
