CONCEPT

Night diving is a great way to enjoy a completely different experience of the sea from that of diving in the daytime. Many divers are fascinated by the mysterious world of the ocean at night, making this recreational activity popular around the world. Today, four special watches that evoke the underwater world at night join The Black Series. The black case expresses the darkness and silence of the night ocean, and the orange color is inspired by the lights that illuminate it.
The four models include three modern re-interpretations of landmark timepieces from 1965 and 1970 with the world view of The Black Series.

    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 12,500km 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.
