Seiko Prospex The 1965 Diver’s Re-creation Limited Edition

July 05, 2023

Seiko’s first diver’s watch is reborn with a
new slimline movement.

In 1965, Seiko introduced its, and Japan’s, first-ever diver’s watch. With an automatic movement and water resistance to 150 meters, the watch 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, thanks to their high quality and reliability, found favor with professional divers and adventurers alike. Today, Seiko introduces a re-creation of the 1965 watch, known to fans as the 62MAS. The new timepiece’s design and dimensions are virtually identical to the original, while its specifications are thoroughly up to date.

Faithful to the original

The watch is faithful to the original in every detail but also features modern enhancements of contemporary Seiko watchmaking. It has a box-shaped sapphire crystal and 200 meters of water resistance for greater reliability. The text on the dial is faithful to the style of the original yet updated to reflect current specifications. The hands and all 12 markers, including the marker by the date window and the pip on the unidirectional bezel, are filled with Lumibrite to enhance legibility in low-light conditions.

Caliber. 6L37

The watch is powered by the new Caliber 6L37, the first movement from the slimline 6L family made expressly for diver’s watches. It features the same accuracy and power reserve as the trusted 6L35 movement that is the mainstay of the 6L family; however, thanks to modifications in construction and material, its durability and shock resistance now meet the strict standards of a Seiko Prospex diver’s watch.

Case Back

The case back bears the same dolphin emblem as the 1965 original.
