Seiko's thinnest automatic Prospex diver yet

Part of a rich legacy of innovation in high-stakes timekeeping, the Seiko Prospex collection continues to celebrate a long history of sports watch excellence with modern re-interpretations of landmark achievements. With the thinnest case to date of any Seiko automatic diver's watch, in stainless steel with super hard coating, this sleekly updated timepiece incorporates the distinctive cushion-shape and recessed crown of one of Seiko's most iconic designs.

Sporty and tailored, this versatile watch includes a curved sapphire crystal with anti-reflective coating on the inner surface, black uni-directional rotating elapsed timing bezel, and screwdown crown and caseback, as well as a black rail-pattern reinforced silicone strap inspired by the original model. The rich black dial features a date calendar and LumiBrite hands and markers. Following ISO standards for scuba diving to depths of up to 200 meters, this exceptional timepiece offers manual winding capability and includes a 24-jewel automatic movement with a frequency of 21,600 vibrations per hour and a power reserve of approximately 70 hours.
