Built For Below: Introducing The Deepwater Meridian 300 Titanium HEV Automatic

Built For Another World

If your summer plans will be taking you beyond the shoreline, you'll want a watch built for the demands of extended time on and below the water. Fishing, boating, and surfing all have their place, but when the surface disappears above you and light begins to fade, dependable equipment becomes essential. Our Deepwater collection is built for that world.

New this season, the Deepwater Meridian 300 Titanium HEV Automatic is expertly engineered for underwater exploration. Purpose-built to venture even deeper, it pairs a lightweight titanium case with a self-winding automatic movement, 300m water resistance, and an automatic helium escape valve.

At the heart of the watch is a 44mm case crafted from grade 5 titanium. Known for its exceptional strength-to-weight ratio and increased surface hardness, grade 5 titanium delivers the durability serious divers demand while remaining remarkably comfortable on the wrist. The result is a watch that feels substantial in capability, not in weight.

Purpose-built for life below the surface, the Deepwater Meridian 300 is water-resistant to 300 meters and equipped with an automatic helium escape valve positioned beside 10 o'clock. During saturation diving, helium molecules can accumulate inside a watch case under pressure. As divers return to the surface, the valve automatically releases trapped helium, helping protect the crystal during decompression.

Inside ticks a reliable Miyota 8215 21-jewel automatic movement that's powered by the movement of your wrist. Surrounding it is a collection of features designed for confidence in challenging conditions, including a screw-down crown, screw-on case back, sturdy crown protector, and a unidirectional ratcheting top ring for tracking elapsed time underwater.

Visibility is critical beneath the waves, so we've included a sapphire crystal with anti-reflective coating and Nemoto LumiNova® SG2200 in-fill for dependable readability when light begins to fade. Applied to the hands and hour markers and even integrated onto the dial itself on one model, the luminous treatment ensures the watch remains easy to read when it matters most.

Completing the build is a UV-resistant HNBR synthetic rubber strap engineered for comfort and durability. Perforations enhance breathability, while quick-release spring bars make strap changes fast and tool-free, whether you're gearing up on deck or heading ashore after a dive.

The Deepwater Meridian 300 Titanium HEV Automatic is a precision instrument designed to perform where conditions become unpredictable and reliability becomes essential.

Some watches fear the water.

This one calls it home.
