In 1986, Seiko launched a diver's watch that set a new standard. It combined Seiko's legendary 1975 design with a 1,000 meter water resistance for saturation diving with a quartz movement that delivered an accuracy that no mechanical diver's watch could match. At the time, and still today, it was recognized as one of Seiko's most important diver's watches. Today, 35 years on, this classic Seiko Diver's watch is re-born with new design features and upgraded professional diver's watch specifications. This is a watch that truly lives up to the promise of the Prospex name.
The 1986 original. A quartz diver's watch made expressly for 1000m saturation diving.

35th Anniversary Limited Edition

It has the 1000m water resistance and helium resistance that saturation diving requires.
The dial color has a gradation from blue to black to dramatize the way that light gradually fades as one dives deeper into the dark, mysterious world of the ocean.
It incorporates the unique one-piece titanium case with its outer protector structure that makes its shock resistance so exceptional.
The crown is marked with a vivid yellow 'Lock' sign and an arrow to indicate the rotating direction. The winding stem is also in yellow so that the wearer can immediately notice if the crown is unlocked.
The strength silicone strap ensures wearability both on a wetsuit and directly on the wrist. Each strap features the text "FOR SATURATION DIVING 1000m" in yellow.
