Citizen Perpetual Calendar, Alarm, Chronograph, Dual Time Zone Collection
CItizen's Famous Perpetual Calendar Alarm Chronograph Collection. Perhaps the world's most technologically advanced timekeeping mechanism in a simple, user friendly designed watch. This watch utilizes Citizen's Eco-Drive Technology which powers the watch by ecologically friendly solar power (any available light). You'll never need to replace a battery again. Perpetual Calendar means the watch automatically keeps track of the correct date, no matter the month, even in Leap Year! Other advanced features include a 1/20th second accurate Chronograph (stopwatch), audible analog alarm, 2nd Independent Time Zone, and a 24 Hour Time Subdial.
