A modern reinterpretation of the 1968 Diver's

This Prospex watch reference SPB381J1 is the modern reinterpretation of one of the Japanese brand's most iconic watches! A contemporary version of the original model released in 1968, it was at its time a revolutionary watch with 300m water resistance and a Hi-Beat 36000 automatic movement, a world first at the time! With a one-piece structure, unidirectional rotating bezel, and screw-down protective crown, this timepiece pushed the boundaries of precision, durability, and ease of use in watches for professional and amateur divers.

For this new release, this model stays true to its heritage in terms of design, but is updated to meet the standards of today's Prospex collection. The case design is inherited from the 1968 original, and the case sides are mirror finished. The unidirectional rotating bezel edge allows for easy control. This watch offers comfort and fit on the wrist by adopting a narrower case size of 42mm. Characterized by a green sunray dial, this watch captures the beauty of green waves washing up on the beach. The hour markers and hands are coated with Lumibrite to ensure optimal readability in the darkest of conditions. The green is also found on the ceramic bezel to add that little touch of pizzazz!

This watch is water resistant to 200 meters and comes on a steel bracelet with a secure extension and clasp. The case has an ultra-hard coating and the sapphire crystal features an anti-reflective coating on its inner surface to ensure great readability from all angles. Finally, this model features a new three-link stainless steel bracelet with a slim profile that allows it to fit securely and comfortably on the wrist.
