The Navihawk men's watch from Citizen features atomic timekeeping for superior accuracy. The chronograph watch has a perpetual calendar and is radio-controlled with world time in 43 cities. Orange accents distinguish the black dial, set in a black ion-plated stainless steel case. A black polyurethane strap embossed with the NAVIHAWK® logo secures the watch. Citizen Eco-Drive is fueled by light, any light, so it never needs a battery.
