An American-made, limited-production Lum-tec Combat B45 GMT field watch that’s built tough enough for multiple lifetimes
The rugged look and classic field stylings of the Lum-tec Combat B45 GMT aren’t just for show—this is one tough watch that can handle all the rigors of your day to day. Every single one of the 500, limited-edition B45s was carefully assembled by hand in Ohio from a surgical steel case powered by Swiss Ronda 515.24H movement, and finished with swappable military-style straps. Like all Lum-Tec watches, the B45 is built to withstand the challenges of a life lived in the field, no matter what that means to you—whether it’s thru-hiking the North Country Trail, rafting the Arkansas River, or just working away at your 9-5. No work is too tough for this Lum-tec Combat B45 GMT field watch.
Every LÜM-TEC watch features exclusive MDV Technology, a special 8-layer application of ultra bright glowing Super-Luminova photoluminescent material. MDV hands and dials are extremely visible in all light conditions, making this watch perfect for red-eye travelers, evening joggers, and casual divers alike.
