Official description

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 recreations and reinterpretations of landmark achievements. Honoring the first watch designed to withstand the dangerous world of professional diving, Seiko's 1975 saturation diver, with its one-piece case, outer shroud and revolutionary L-shaped protective gasket, this extraordinary reinterpretation retains the solid can-like lines and functionality of the original, improved with upgraded specifications and materials. Crafted, like the original, with a light and durable one-piece titanium inner case, it also includes a ceramic outer case and a one-way rotating elapsed timing bezel in Seiko's new Ever-Brilliant Steel, offering an exceptional level of corrosion resistance. Rose gold-tone accents frame the black dial designed with arrow-shaped LumiBrite minute hands and simple geometric indices for sharper legibility in underwater conditions. With a sapphire crystal, screwdown crown, and silicone strap, this exceptional watch, following ISO standards for diving to depths of up to 1,000 meters, features a 26-jewel caliber 8L35 automatic movement, assembled expressly for diver's watches at the Shizukuishi Watch Studio, and offering a frequency of 28,800 vibrations per hour, power reserve of approximately 50 hours, and manual or automatic winding capabilities. 1,000m Water Resistant
