Prospex Solar Hybrid Diver - Modern Interpretation of the 1982 Hybrid Diver's Watch. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and winning design. This superbly functional timepiece is a modern interpretation of Seiko's 1982 landmark H558-5000, the first hybrid analogue-digital diver's watch with alarm and chronograph. Essential equipment on several expeditions to Mount Everest, the design was also featured in a number of hit action films. The digital display offers time, date, alarm and chronograph readouts with a stopwatch function, power reserve indicator and dual time capability, while the black analogue dial features LumiBrite hands and markers. The energy-efficient Solar Cell, powered by any light source, with no battery change required, provides a 6-month power reserve when fully charged. With a black one-way rotating elapsed timing bezel, this versatile watch includes a lightweight matte black case, secure screwdown crown, pushers and caseback, and durable silicone strap, and meets ISO standards for scuba diving. 200m Water Resistant
