This versatile timepiece reimagines Seiko's 1965 first diver's watch, an automatic timepiece with a then exceptional water resistance of 150 meters. Offering an extraordinarily legible dial and durable enough to become standard equipment on the Japanese Antarctic Research Expedition (JARE), this landmark timepiece propelled Seiko into the forefront of dive watch design. With contemporary styling and upgraded specifications, this new reinterpretation reflects the look of the 1965 original, but with a sleeker and thinner case designed to fit more comfortably on the wrist.
