SUMMARY: This is the new solar-powered version of our popular Korean War field watch, which was first introduced into the Vaer lineup in 2021. Why have we transitioned to solar? In our opinion, solar movements provide the best of both worlds - perpetual timekeeping with incredible accuracy. Six hours of sunlight will provide six months of power reserve, and the watch can run off any light source (even candlelight). In terms of aesthetics, the C5 Korean Field stands out in the Vaer line-up as a modern homage to service watches worn by allied soldiers in the Korean War in the 1950s. As a C5 model, this watch is part of our all-time bestselling collection, distinguished by its ocean-ready functionality, low-profile case design, ultra-accurate solar quartz movement, and full USA assembly. WHO IS THIS WATCH FOR? We recommend the C5 for those seeking a dependable tool watch that can also be dressed up for more formal occasions. The perpetual timekeeping function of a solar-powered quartz watch makes it the perfect fit for an everyday wearer, and the 40mm case sizing is large enough to command presence on most men's wrists while still maintaining our commitment to ergonomic, and timeless proportions. INSPIRATION: In building the C5 Korean Field our goal was to bring attention to the Korean War, and deliver a more affordable counterpart to our WWII-inspired automatic A12 Dirty Dozen. In addition to historically accurate dial design, the caseback on this model features a unique deep-etched engraving. Replacing the Vaer logo at the center is an etching of the Korean Peninsula which serves as a reminder of the sacrifice and commitment of thousands of allied soldiers who served in the conflict, and the countless casualties resulting from the war. Since its original launch, the Korean Field has earned a permanent place in the Vaer lineup thanks to its combination of "set-it-and-forget-it" outdoor functionality and a connection to the iconic history of military timekeeping.
