Sleek styling, chronograph dials and scales for height and speed point to adventure in this Ecosphere men's watch from Citizen. The black textured dial is set in a 48mm black ion-plated stainless steel case, paired with a black ion-plated stainless steel bracelet secured with a push-button fold-over clasp. The men's chronograph watch features an Eco-Drive movement, powered by light, so it never needs a battery.
