PROSPEX SLA053

Limited Edition of 500

Seigaiha U.S. Special Limited 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 a long history of sports watch excellence with re-creations and re-interpretations of landmark achievements. This U.S. Special Edition, available only in a limited edition of 500, with each caseback engraved to show the watch’s position in a controlled-production run, 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 intense blue dial and the deep black of the high-performance one-piece stainless steel case with black hard coating evoke the ocean under moonlight. 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. With an anti-reflective sapphire crystal, date window and screwdown crown, this high-intensity timepiece includes a black silicone strap and is packaged in a special collectors’ box. 300m Water Resistant
