The start of a tradition

Seiko created Japan's first diver's watch in 1965.
This watch inaugurated five decades of innovation that have made Seiko diver's watches the global standard. Seiko's first high-beat diver's watch, created in 1968, is an important part of this tradition.

With a 10-beat high precision automatic caliber, a one-piece structure, a mono-directional rotating bezel and screw-down protection crown, the success of this model laid the foundation for the Seiko diver's watch development which has now, for 50 years, pushed back the frontiers of precision, durability and ease of use in watches for professional and recreational divers.

Explore the history of Seiko diver's watches

A faithful homage with the latest functions

This model is a re-creation of the classic 1968 model,
but with greatly enhanced specifications that incorporate
the latest advancements in
Seiko’s craftsmanship and technology.

A sharp case design

Like the original version, this recreation features a flat case with a sharp design. Seiko's unique Zaratsu polishing techniques accentuate the edges, bringing additional sharpness and beauty to the lugs.

A flat case back,
faithful to the original

While the original model was an air diver's watch,
the re-creation has been upgraded for saturation diving
via a resilient one-piece case structure.
Even with this enhanced specification,
the watch rests easily on any size wrist.

Enhanced legibility.

Each of the three hands has a different design,
length and width and the LumiBrite on each has
a distinct shape so that the time is easily read,
under any circumstances. The dual-curved sapphire
crystal delivers exceptional clarity
from any viewing angle as well as enhanced durability.

Distinctive markers and
long-lasting LumiBrite

The differentiated 12, 6, and 9 markers ensure that
the watch can be read without error even 300 meters down.
The contrast of the black dial and special,
long lasting LumiBrite allows for legibility
even in the darkest environments.
The mono-directional rotating bezel ensures
the absolute safety that divers require.

Based on the original design, the strap is made from a state-of-the-art material.

The original strap design has been
re-created in high strength silicone,
adding reliability while retaining comfort.

Caliber 8L55

This re-creation incorporates a
Caliber 8L55 10-beat movement,
specially optimized and adapted for use in
a diver's watch with this structure.
This caliber beats at 36,000 vibrations per hour and
has a power reserve of 55 hours,
and it is also assembled by
Seiko's leading craftsmen at the
Shizukuishi Watch studio.

Modern aesthetics for a historic design

Rather than recreations, these two models are modern re-imaginings of the 1968 classic.
The overall designs are faithful to the original and based on a flat and sharp design.
These watches are equipped with Caliber 6R15 automatic movements, allowing for a slimness
that combines with the shape of the hands to create a more modern look.
The first one has a black bezel and a stainless steel bracelet,
and the second has a blue bezel and an extra-strength silicone strap.
Both incorporate the eye-catching style of Seiko with the exceptional
reliability and functionality synonymous with the Prospex brand.
