Discover our collection of toughest tool-watches crafted from carefully selected materials. We employ an industry-proven thermochemical surface treatment process that modifies the properties of the material itself. Unlike surface coating techniques such as PVD, CVD, and DLC that merely apply a thin layer over the metal, our process involves a thermochemical reaction. Through this process, nitrogen ions diffuse into the material’s surface, resulting in a case-hardened outer layer. This treatment enhances hardness, wear resistance, and other desirable characteristics, making our watches engineered to withstand the most demanding environments while ensuring improved working lifespan, strain limit, and fatigue strength.

Note: Our industry surface treatment process should not be confused with surface coating techniques. Unlike coatings that may eventually peel, crack, or flake off due to poor adhesion between the coating and substrate, our process modifies the material itself, providing a durable and long-lasting solution.
