A mighty Prospex diver inspired by cave exploration
Seiko's first diver's watch was born in 1965. With water resistance to 150m and an automatic movement, it proved its high quality and reliability when worn by members of the 8th Japanese Antarctic Research Expedition in 1966. Thanks to the positive reaction of the members of the expedition on their return, Seiko's diver's watches were chosen by the same research team between the years 1966 and 1969, during which time the landmark Seiko diver's watch with 300m water resistance and a 10-beat automatic movement was created, in 1968. New for 2023, Seiko introduces into the Prospex collection a new interpretation of that hallmark 1968 diver's watch.
While the design reflects its heritage, every aspect of this new creation exemplifies the high levels of diver's watch technology for which the Prospex collection is renowned, while adding in a visual touch as a nod to its capability: a dual-gradient textured blue dial inspired by underwater cave walls when illuminated by a diver's torch. To further ensure the watch's durability, the crown is not screwed directly into the case but locked into a separate component that is built into the case and so can be more easily replaced.
The watch is powered by Caliber 8L35 which was developed especially for diver's watches and is hand-assembled by the craftsmen and at the Shizukuishi Watch Studio in northern Japan. The movement's rigidity and accuracy ensure the highest possible levels of performance in the most demanding environments, both on land and under water.
