The LUM-TEC Combat B64 Chronograph is a bold and durable timepiece designed for extreme performance and everyday wear. Featuring a 43mm heat-treated 316L stainless steel case with a military-grade gunmetal PVD coating and bead-blasted finish, it offers rugged resilience and 200 meters of water resistance. The matte gray dial is complemented by diamond-cut hands and ultra-bright X1-grade Super-Luminova for exceptional visibility in all lighting conditions. Powered by the reliable Miyota OS21J chronograph movement, it includes a 60-minute timer, 24-hour subdial, and a 5-year battery life supported by anti-shock movement mounting. Limited to just 500 numbered pieces worldwide, the watch comes with both a leather and a heavy-duty nylon strap, making it as versatile as it is tough. Hand-assembled and tested in Ohio, the Combat B64 blends American craftsmanship with military-inspired performance.
