Time was originally a local phenomenon. The wearers of the early watches would pass there town’s main reference of time, be that a cannon fired to mark mid-day or a clock mounted on a public building on a regular basis. Today however, a more convenient solution are Radio Controlled Watches.
As the world became more connected and people began to travel regularly, central time became more important. This ensured that those travelling or communicating over distances had a common reference. Today these co-ordinated time sources are available over huge distance due to radio transmissions of time signals controlled by these central clocks. The signals are received by a number of devices including radio controlled watches.
Radio Controlled Watches - Accurate time is always at hand
Modern radio controlled watches are a great way to ensure that you always have the correct time at hand. The time is received from a radio transmitter linked to an atomic clock. These transmitters send a form of computer code known as a time code. This allows radio controlled watches to be set automatically from the signal. They will also automatically adjust for time zone changes when travelling long distances and will auto correct for changes in summer/winter time or leap seconds.
Watches in the radio controlled watches section are available from major brands including Casio and Citizen watches and are available in a number of styles although bracelets do tend to be the dominant style in this type of timepiece.Powered by battery the watches use long-wave radio receivers that are relatively economical in their power usage. Although most areas of the world offer reception, outside of zones where radio control signals are available the watches use the reliable method of quartz technology to ensure that they continue to give a useful time reference until they can re-synch with one of the broadcast master clocks.
