NEPTUNE
SERIES IV
The quintessential dive watch.
The Neptune is our flagship diver, an ode to the references worn and made famous by midcentury icons from James Bond to Jacques Cousteau. It’s designed as if it came straight out of 1957; with its classic size, gilt details, puffy lume plots, flat link bracelet, all topped by a bubbly Hesalite dome.
New to Series IV is a luminous acrylic bezel insert, a more durable version of the Bakelite rings commonly used in the ‘50s. Additionally, we made small, but impactful changes integrating owner feedback from previous generations: slightly shortened lugs, thinner bracelet links, repositioned lug holes (minimizing the gap when worn with a 2-piece strap), and more distinct hour and minute hands.

A NEW CLASSIC
For most of us, a well-styled vintage dive watch is an impossible dream. Obtaining one and getting it running is difficult enough (not to mention expensive). Using it for its original intended purpose is another challenge entirely.
The Neptune is that dream come true. It has the style of dive watch icons and the substance that made them legendary.
Shown further down on a 6 in. wrist.
OLD-SCHOOL COOL
Just like its forebears, the Neptune sports a Hesalite crystal. It's stood the test of time on the wrists of explorers, mountaineers, divers, and even astronauts. It has a distinct clarity and charm sapphire just can't replicate.
Afraid of scratches? The Neptune includes a Polywatch tube and polishing cloth to keep it looking like new.
ABSOLUTELY BRILLIANT
The Neptune uses BGW9 Superluminova on its hands, markers, and bezel. On the dial, the luminous compound is 3D printed at a thickness of 0.3mm to make for easy reading in low-light conditions.
READY FOR ACTION
Ticking inside the Neptune is the 90S5, a no-date variant of Miyota's 9 series premium automatics.
It offers a combination of thinness, reliability, and accuracy unlike any other movement on the market.
modeled on 6 in. / 15.25 cm wrist
