Thanks to its simple and functional design, this strap is perfectly suited for daily, sports, or nautical use. It is suitable for both modern watches and models with a military or vintage style.

Attachment system and case fitting

The strap is designed for a lug width of 20 mm and accepts spring bars up to 2 mm in diameter.

Using spring bars of an appropriate diameter reduces play between the strap and the watch lugs. A thicker bar can also help bring the strap closer to the case for a more precise fit and better visual integration.

Aerospace-grade fluorocarbon rubber

Made from vulcanized aerospace-grade fluorocarbon rubber, this strap stands out for its exceptional durability, stability, and superior comfort.

It effectively resists water, sweat, temperature variations, and the stresses of daily use, while maintaining its flexibility and premium appearance.

Tips for a perfect fit

Before installation, verify that your watch corresponds to one of the compatible references listed above and that it has a lug width of 20 mm.

For the best possible fit, choose spring bars whose length and diameter precisely match the lug holes of your watch. A spring bar that is too thin can create play, while one that is too thick can be difficult to install.

After mounting, check that both ends of each spring bar are properly engaged in the lug holes before wearing the watch.
