Prospex Seigaiha-Inspired U.S. Special Edition. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. Part of a rich legacy of innovation in high-intensity timekeeping, Prospex continues to celebrate over 60 years of sports watch excellence with recreations and reinterpretations of landmark achievements. This U.S. Special Edition celebrates the "seigaiha" or "blue ocean waves" pattern, deriving from an ancient Japanese tradition as a symbol of peace, good luck and good fortune. The rich burgundy dial evokes the sea at daybreak. Following ISO standards for saturation diving at depths of up to 300 meters, this exceptional timepiece is powered by a 26-jewel caliber 8L35 automatic movement, assembled expressly for diver’s watches at the Shizukuishi Watch Studio, with the increased torque necessary for the most challenging dives. This mechanical movement beats at a frequency of 28,800 vibrations per hour, with a power reserve of approximately 50 hours, and offers manual winding capability. For enhanced legibility, the hands and markers feature LumiBrite coating, with LumiBrite accents on the black ceramic uni-directional elapsed timing bezel. Offering a high-performance one-piece case in stainless steel with super-hard coating, this durable high-intensity timepiece includes an anti-reflective sapphire crystal, date window, screwdown crown, stainless steel bracelet with super-hard coating, tri-fold push button release clasp with slide adjuster, and additional black silicone strap. Packaged in a special collectors' box. 300m Water Resistant
