Feel at ease with functionality and style. The Citizen Promaster Divers CB5001-57E watch features a radio-controlled time-keeping function that captures a time signal in four areas around the world and automatically adjust the time. Fitted with a 1/1 second chronograph that can measure up to 60 minutes, an aviator slide rule and a world time function for instant switching to the time of 24 cities, this is a pilot’s watch with multi-functions and a high level of practical utility. Featuring sleek black dial with sapphire crystal glass and 200 meter water resistance, this watch is definitely a winner!
