Radio controlled watches

Radio-controlled watches combine precise timekeeping with everyday functionality. Thanks to modern technology, they automatically adjust to the exact time, offering outstanding reliability.

How does a radio-controlled watch work?

A radio-controlled watch uses a quartz movement powered by either a battery or solar energy to keep accurate time. Through an internal antenna, the watch receives a radio signal that automatically adjusts the time, hence the name radio-controlled watch. This signal comes from an atomic clock and is received regularly, usually at night, to ensure the time remains precise. Changes to summer and winter time are also taken into account. Atomic clocks are installed in radio towers to transmit a uniform time signal. Six radio towers located across Europe, Asia and America ensure the permanent transmission of the exact time worldwide. Although multi-frequency radio-controlled watches can receive multiple time signals, they do not necessarily cover all six of the globally available stations. Depending on the model and region, manual adjustment may still be required, especially when travelling across continents. Unlike radio-controlled watches, GPS watches receive the time signal directly from satellites and automatically adjust to the correct time zone anywhere in the world.

In order for the radio-controlled watch to automatically adjust the time, it is essential that the radio signal is not subject to interference. Reception disturbances are rare in everyday life and are usually temporary. However, thick walls, metal, or electronic devices in close proximity can affect signal reception. In such cases, the watch does not stop and can automatically resynchronise as soon as it is back within range of the transmitter. This can be done by placing the radio clock on a windowsill for several hours. It is also important to ensure that the watch contains a new or fully charged battery, as synchronisation with the transmitter requires a lot of energy. If necessary, the watch can also be set manually.

Most radio-controlled watches are powered by batteries that typically last between one and five years, depending on the model and how they are used. Radio-controlled solar watches obtain their energy from sunlight and store it in a rechargeable battery. By wearing the watch on a regular basis, it can sustain the watch indefinitely without recharging.

Whether featuring an analog dial or a digital display, radio-controlled watches for men and women ensure precise timekeeping. They also offer many practical functions such as a calendar, alarm, or world time, providing everyday convenience.
