Engineered for precision and durability, the Lum-Tec B65 Chronograph is a rugged timepiece built to thrive in extreme conditions while maintaining a sleek, tactical aesthetic. Its 43mm forged 316L stainless steel case, bead-blasted and coated in military-grade gunmetal PVD, undergoes heat treatment for enhanced hardness—making it as tough as it looks. Water resistant to 200 meters and powered by the reliable Miyota OS21J chronograph movement, it features a 60-minute timer, 24-hour sub-dial, and boasts a 5-year battery life backed by a shock-resistant mounting system.
The matte gray dial is stealthy yet legible, equipped with diamond-cut hands and 30 layers of custom X1-grade Swiss C3 GL lume using Lum-Tec’s proprietary MDV® Technology. Domed sapphire glass with military-grade AR coating ensures crisp visibility in any light. Paired with two rugged military-style straps—gray nylon and leather—each with matching gunmetal hardware, the B65 is more than a tool watch; it’s a mission-ready companion.
Hand-assembled and tested in Ohio, this limited edition of 500 offers lifetime battery replacement and pressure testing, standing as a bold testament to American watchmaking grit.
