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.

Saturation Diving 1000m

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.

Titanium Case &
Ceramic Outer Case Protector

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.

Silicone Strap

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.

The Prospex "1986 Quartz Diver's 35th Anniversary Limited Edition" S23635J1 is offered with extra-strength silicone straps in both black and blue-gray colors. It features a one-piece case construction and carries the individual watch's serial number on the case back. The watch is equipped with the quartz caliber 7C46 which delivers a high level of torque so that it can move the powerful hands that are wide, robust and Lumibrite-coated for maximum legibility. The watch has a thickness of 16.3mm, diameter of 49.4mm, and a length of 49.4mm. Bracelet length is at 210mm. Other features include Day/Date Display, Screw Down Crown, Unidirectional Bezel, and LIMITED EDITION is engraved on the case back. Lumibrite is also applied on the hands, indexes and bezel.
