Featuring a Japanese solar-powered movement that lasts up to 4 months and eliminates the need for battery changes, our Expedition® Field Solar is a military-inspired outdoor watch made to accompany you anywhere. It also boasts a rugged two-piece 43mm metal case, 50m water resistance rating, and a tan sustainable fabric strap made from recycled plastic. And thanks to the luminescent hands and dial markings, the sun works overtime to make this watch legible in the dark.
