October 5, 2022 – Seiko Watch of America has announced three Special Edition Prospex timepieces inspired by the beauty and mystery of undersea caves and the daring of those dedicated to exploring these fascinating and dangerous environments. Exclusively available in the U.S. market, these extraordinary new watches also pay tribute to the brand’s pioneering advances in diver’s watch technology.

By the late ’60s, when Seiko diver’s watches were already setting new standards for high-intensity timekeeping, a letter from a professional diver posed a new challenge – there was no watch available, however advanced, that could withstand the rigors of true saturation diving. Seiko immediately formed a research team to address this vital need, working for seven years to produce a watch that completely redefined underwater timekeeping. Among the many innovations of this landmark watch was the first use of titanium in a diver’s watch – offering an unprecedented degree of lightness, durability and corrosion resistance. Fittingly, the new Prospex U.S. Special Editions are crafted of titanium as well, with the addition of a super-hard coating making them perfect for extreme underwater environments.

With distinctive patterning to suggest the natural formations and mineral deposits of undersea cave walls, the dials, available in light-green, blue-gray or blue-green, evoke the changing tones viewed by divers as their safety lights illuminate these deep-water caverns. Each dial is framed by a uni-directional rotating bezel to track elapsed time, with a subtle two-tone finish to express the duality of light and dark within these mysterious undersea worlds. And, to provide the utmost in visibility, the distinctively formed hands feature LumiBrite coating, while the durable sapphire crystals include anti-reflective coating on the inner surface.

Following ISO standards for scuba diving at depths up to 200 meters, these high-intensity watches also offer secure screwdown crowns and casebacks, as well as tri-fold push button release clasps with secure locks and extenders to easily fit over a wet suit. As versatile as they are durable, the bold and rugged cases and bracelets are crafted with well-defined and sophisticated lines perfect for less hazardous everyday adventures.

Inside, Seiko’s proprietary 24-jewel automatic movement, Caliber 6R35, beats at a frequency of 21,600 vibrations per hour, with a power reserve of 70 hours, and both manual and automatic winding capabilities.

The new Prospex U.S. Special Edition designs will be available at select Seiko retailers in October 2022, each with a suggested retail price of $1,500.
