Built for adventure and crafted with precision, the Lum-Tec M91 is a timepiece that embodies rugged durability and high-end performance. Designed and meticulously assembled by hand in Ohio, this limited-edition watch (only 300 worldwide) features a forged and heat-treated 44mm 316L surgical-grade stainless steel case, ensuring unmatched resilience. With 600 meters of water resistance, a Swiss Sellita SW200-1 automatic movement, and an anti-shock mounting system, this watch is engineered to handle extreme conditions while maintaining flawless accuracy. The curved sapphire crystal with military-grade AR coating enhances clarity, while the MDV® luminous technology with Swiss Super-Luminova X1 C3 provides unparalleled visibility in low light.
From the solid double diamond-sealed caseback to the 120-click unidirectional luminous bezel, every detail of the Lum-Tec M91 is built for precision and performance. Two versatile straps—a leather and a rubber option—allow for seamless transitions between adventure and everyday wear. With lifetime free timing adjustments, seal cleaning, and pressure testing, the M91 is more than a watch—it's a commitment to excellence. Secure yours before this exclusive series disappears!
