Citizen Eco Drive Radio Controlled AS6000-59A Men's WatchWith radio-controlled time update, the last thing you need to worry about is how accurate your watch is. The radio-controlled technology captures signals from atomic clocks that are sent from radio towers. The Automatic Reception Function of this watch leaves nothing that you should set manually unless you want it to; for the latter, there is an On-Demand Reception feature that helps to update time at your own will.
