Focus

Shock resistant
The 360° protection system is designed in-house and made in Italy to the highest standards. It is realised in a special blend of thermoplastic polyurethane (TPU) material. Its custom construction, composed of a 360° protection shell that perfectly holds the movement and a dial top protective ring, allows the watch to withstand extreme environmental stress while still keeping it super light.
CUSTOM Variable font
The variable font system is a custom-designed watch typeface that can be finely tuned for optimal legibility, weight, and dial production techniques—offering endless variations in numeral thickness and width.


Everyday-ready watch
The Toolwatch line is engineered to endure the harshest conditions. It has been tested to meet MIL-STD-810 standards—a U.S. military specification that ensures equipment is built and tested for real-world environmental challenges.
TRAVEL-READY GMT & DATE complications
The GMT and date complications make your toolwatch more than just a tool, but a true travel companion. Whether you’re crossing time zones or just navigating a packed day, these features add a layer of ease and versatility that fits any journey.
