The Legend Reborn

Military-tough. Field-proven. Now with modern upgrades.

You asked, we listened. The iconic UDT is back revived by popular demand and rebuilt for the modern age. Inspired by the rugged military timepieces of the 1980s including the one worn by Sylvester Stallone in Rambo: First Blood Part II this new version stays true to its roots while pushing the limits of durability and function.

Still brutally tough. Still unapologetically purpose-built. Now better than ever.

✅ Upgraded Digital Display – Larger, clearer, and easier to read in any conditions.
✅ Sapphire Crystal – Scratch-resistant, ultra-clear.
✅ Ceramic Bezel – Virtually scratchproof with crisp, tactile clicks.
✅ 200M Water Resistance – Fully equipped for serious underwater missions.
✅ High-Performance Quartz Movement – Built for precision in extreme environments.
✅ Classic 80s Military Design – A nod to the original UDT worn in Rambo: First Blood Part II.
✅ Assembled in Canada – Tested in the Pacific Northwest for real-world grit.

It's more than a watch—it's a piece of watchmaking history, reborn for a new generation.

Inspired by Action

Following in the footsteps of legendary timepieces, the new Momentum UDT embodies the spirit of adventure. Its predecessor, the original Chronosport UDT from the 1980s, rose to fame on the wrists of special-operations forces worldwide. The UDT's rugged functionality was further immortalized by Sylvester Stallone in Rambo, solidifying its reputation as a watch built for action.
