Launched in 1970, this diver's watch with a unique streamlined form was worn by adventurer Naomi Uemura between 1974 to 1976 when he completed a 12,000km solo dog-sled run from Greenland to Alaska, proving its reliability in extreme conditions. While maintaining the case form of the original, the water resistance has been increased from 150m to 200m and the glass material has been upgraded to sapphire glass.
