Citizen has been the world's largest watchmaker since 1986.  Beyond sheer size, Citizen is also recognized as a worldwide leader in advanced technology.  From the world's slimmest LCD watch to the first voice recognition watch and the world's first professional dive watch with an electronic depth sensor, Citizen's record of  "world firsts" is unmatched.  Most recently, Citizen has staked out a new position as the leader in Ecologically Friendly timekeeping with its Eco-Drive collection o flight powered watches.  With models ranging from dress to sport to professional dive watches, Citizen Eco-Drive  runs continuously in any kind of natural or artivicial light for a lifetime of use.  Fueled by light, it never needs a battery.  With the introduction of Skyhawk A-T radio controlled atomic-timekeeping flight chronographs, Citizen reaffirms its position as a leader in timekeeping technology.
