Seiko Prospex

Seiko's professional sports line, and the heart of its dive heritage. 'Prospex' stands for Professional Specifications, and the line spans sea, land, and sky, with dive watches at its core, built to ISO standards. The history is deep: Seiko's 1965 62MAS was Japan's first diver's watch, followed by world-firsts in hi-beat, titanium, and quartz professional divers, plus the '6105' worn on screen in Apocalypse Now that collectors call the 'Willard.' Modern hits include the 62MAS reissue, the Turtle, the Samurai, and the Tuna. Whether you want an affordable everyday diver or a serious tool watch, this is the line.
