Lum-Tec Combat B57

The rugged look and classic field stylings of the Lum-tec Combat B57 aren’t just for show—this is one tough watch that can handle all the rigors of your day-to-day. Each of the 200, limited-production B57s was carefully assembled by hand in Mentor, Ohio (near Cleveland) from a surgical steel case powered by Swiss Ronda 515 jeweled movement, and finished with two swappable military-style straps. Like all Lum-Tec watches, the Lum-Tec Combat B57 is built to withstand the challenges of a life lived in the field, no matter what that means to you—whether it’s through hiking the Pacific Crest Trail, rafting the Arkansas River, or just working away at your 9-5. No work is too tough for this field watch!
