Synchron launches the SEALAB Ti300M: A Modern Titanium Tribute to 1970s Dive Watch Heritage
Synchron, renowned for reviving brands like Aquadive, Synchron, Tropic straps, and ISOfrane, today announced the launch of the SEALAB Ti300M, a professional dive watch that sets a new benchmark in titanium watchmaking and underwater performance.
The SEALAB Ti300M derives its name from its defining characteristics: a titanium case paired with 300-meter water resistance. An homage to the great dive watch creations of the 1970s, the SEALAB Ti300M is the first model in Synchron's new SEALAB line, updating classic proportions with modern materials and engineering. With a 41mm diameter and 11.9mm height, the watch balances wearability with professional dive watch functionality.
"The SEALAB Ti300M embodies our vision of watchmaking that honors tradition while embracing the future," said Rick Marei, CEO of Synchron. "Every component has been meticulously engineered to deliver exceptional performance and enduring beauty that our clients expect from a Synchron timepiece.

A tribute to the golden age of dive watches

SYNCHRON Ti300M | POSEIDON EDITION

The new Synchron Titanium. Built with Poseidon. Built to dive.
Ten years ago, Synchron and Poseidon began working together — two houses with deep roots in their own fields, brought together by a shared conviction: the diver comes first. A decade on, that partnership has shaped a tool watch tested where it matters, in the water.
The new Synchron Titanium is the lightest expression of that philosophy yet. 50 grams. 11.9 mm thin. Light on the wrist, easy under a wetsuit, comfortable from the first dive of the day to the last. Grade titanium delivers the toughness of a professional instrument with a wearability few dive watches can match.
Both brands carry rich histories of their own. Poseidon helped define modern diving equipment. Synchron, from the golden age of dive watchmaking, shaped the tools the industry was built on — including the legendary TROPIC® strap. The new Titanium channels that combined heritage into something modern, light, and unmistakably purposeful.
Professional specs. Honest price. No theatre.
Synchron Titanium — built to dive.

Three-dimensional luminous indices

SYNCHRON Ti300M | POSEIDON DEEP BLACK

Sculpted, not printed. Cut in the shape of each hour marker and pinned to the dial.

The hour indices are not printed and not applied lume plots. They are 3D-BRYTE technology indices — three-dimensional luminous pieces, cut in the shape of each index and fixed to the dial with two pins each for permanent alignment.

The extra luminous mass makes them read brighter in the dark, and the sculpted-piece construction makes them read as distinct objects on the dial in daylight — almost like small ceramic tiles pinned to a matte black plane.

Two heritage brands connected by a shared spirit of adventure.

Poseidon & Synchron

Poseidon:
Founded in Sweden in 1958, Poseidon has spent more than six decades at the forefront of diving equipment. From the first single-hose regulator to advanced rebreathers used by professional and military divers around the world, the brand has built its reputation on engineering that performs when conditions are at their hardest. Poseidon doesn’t follow the diving industry — it has helped define it.

Synchron:
The Synchron name has a storied place in Swiss watchmaking. From 1968 to 1980, Synchron was a Swiss holding company that brought together three historic houses — Cyma, Doxa, and Ernest Borel — uniting some of the most respected names of the era under a single roof in Le Locle. After the quartz crisis dispersed the original group, the Synchron name was reborn decades later with the same spirit: to preserve and revive the great heritage brands of Swiss diving and watchmaking. Today’s Synchron is the steward of legendary names including Synchron, Aquadive, TROPIC®, and ISOfrane — and the maker of its own focused collection of purposeful dive watches
