One Watch. Two Time Zones. Endless Possibilities.
Why settle for an ordinary dive watch when you can have so much more?
The Core Diver GMT combines the rugged capability of a professional dive watch with the versatility of a Swiss automatic GMT.
Its dedicated 24-hour GMT hand lets you track a second time zone — ideal for international travel, staying connected to home, or managing business around the globe.
From the ocean floor to the other side of the world, the Core Diver GMT is ready.
Engineered for the Extreme — 600 Meters of Water Resistance
Not all dive watches are created equal.
Every Core Diver GMT is individually immersed in water and pressure-tested to meet its remarkable 600-meter / 2,000-foot / 60 ATM water-resistance rating.
Whether you're scuba diving, spearfishing, exploring the ocean, or enjoying everyday adventures, this watch is engineered for demanding conditions.
An automatic helium escape valve adds specialized functionality for demanding diving environments.
This isn't just a watch that looks ready for adventure. It's built for it.
Sapphire Construction. Brilliant Visibility.
The Core Diver GMT features a substantial 4.0mm-thick sapphire crystal with an anti-reflective coating for exceptional clarity.
Its premium unidirectional sapphire bezel delivers 120 precise clicks and features seven layers of Swiss C3 Super-LumiNova on the markers.
Powerful Swiss C3 luminescence on the dial's key elements provides outstanding visibility in low-light environments.
The result is exceptional durability, brilliant legibility, and unmistakable wrist presence.
Swiss Automatic GMT Precision
At the heart of the Core Diver GMT beats the Swiss-made Sellita SW330-2 automatic GMT movement.
Individually regulated for enhanced accuracy, this premium mechanical movement operates at 28,800 vibrations per hour (4Hz) and offers a 54-hour power reserve.
No batteries. Just exceptional Swiss mechanical engineering powered by the movement of your wrist.
Only 100 Made Per Color. Individually Numbered.
Exclusivity isn't just a promise. It's built into every watch.
Each Core Diver GMT color variation is limited to just 100 individually numbered pieces.
This isn't a mass-produced watch you'll see on every wrist. It's a distinctive small-batch timepiece created for collectors, travelers, and adventurers who appreciate something genuinely different.
American-Assembled. Backed for 5 Years.
Every Ocean Crawler is assembled in the USA and individually tested to meet our demanding quality standards.
We proudly stand behind the Core Diver GMT with our comprehensive 5-year warranty.
