A stealthy twist on a Seiko Prospex icon

This is a black version of Japan’s first-ever diver’s watch, the model from 1965 that is known to fans as the 62MAS. While the stealth design reflects its heritage, every aspect of this new creation is fully up to date in specification and execution. The bevel between the upper case and case side, as well as the surface around the bezel display, are Zaratsu polished to achieve a mirror finish before being treated with a hard black coating for a distinctive look. The watch is offered on a fabric strap that features a traditional braiding technique from Japan called Seichu, resulting in strength that meets the demanding standards of Seiko diver’s watches. This model features long-lasting bright Green Lumibrite Pro on the hour and seconds hands and the indexes. The lume shines a vivid green wherever you are, even in the darkest places. The black dial keeps reflection to a minimum, ensuring the highest level of legibility.

While the watch’s design reflects its heritage, every aspect of this new creation is fully up to date in specification and execution. The watch is powered by Caliber 8L35, developed especially for diver’s watches and hand-assembled by Seiko’s most skilled craftsmen and women. The movement’s rigidity and accuracy ensure the highest possible levels of performance in the most demanding environments, both on land and under water. All twelve-hour markers have a generous coating of Lumibrite, as do the hands, and the crystal is a dual-curved sapphire with anti-reflective coating on the inner surface to ensure high legibility from every angle. The strap is produced in silicone for greater strength and comfort.
