Seiko Prospex Black Series Limited Editions

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.

Three modern re-interpretations of the 1965, 1968 and 1970 diver's watches are equipped with Caliber 6R35, which delivers a power reserve of 70 hours.

Dial & bezel

Seiko Prospex The Black Series Limited Editions. 1965 / 1968 / 1970 Mechanical Diver's Modern Re-interpretations

1965 Mechanical Diver's Modern Re-interpretation SPB253J1

1965 mechanical diver's original model

Japan's first diver's watch, launched in 1965. The watch proved its reliability when used in the harsh environment of Antarctica in the 1960s. The new creation is true to its heritage in design, but is updated to the standards of today's Prospex. The watch is perfect for daily use with a slim profile and the low center of gravity of the case.

1968 Mechanical Diver's Modern Re-interpretation SPB255J1

1968 mechanical diver's original model

The original model released in 1968 was a groundbreaking model with 300m water resistance and a 10-beat automatic movement. While retaining the sharp and powerful design of the original model, it offers comfort and fits on the wrist by adopting a smaller case size of 42mm.

1970 Mechanical Diver's Modern Re-interpretation SPB257J1

1970 mechanical diver's original model

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.
