55 years ago, Seiko introduced its, and Japan's, first ever diver's watch. With an automatic movement and water resistance to 150m, it proved its reliability when it was used by members of the Japanese Antarctic Research Expedition from 1966 to 1969. In the years that followed, Seiko created many other diver's watches that found favor with professional divers and adventurers alike, thanks to their high quality and reliability.
Three of the most important landmarks from Seiko's first decade as a maker of diver's watches are now re-created in celebration of the 55th anniversary of that first achievement. They are offered in the Prospex collection which is today synonymous with excellence in watches for use in all types of sports and challenging environments.
