Citizen Radio-Controlled continuous precision

When the time always has to be just right, the best solution is not having to think about it.

CITIZEN Radio-Controlled is the collection designed for those who want a watch that automatically aligns with an official time reference.

These models receive a low-frequency radio signal transmitted by reference stations connected to atomic clocks (instruments that define time with extremely high accuracy).

The result is a professional experience: the time remains correct and consistent over time, with minimal manual adjustments.
In daily use, the watch can synchronize automatically (often at pre-set times, for example at night) and update the time display when you change time zones or when daylight saving time goes into effect, if supported by the model.

It is ideal for travelers, those who work with deadlines and appointments, or anyone looking for the peace of mind of a time that is always in sync.

Radio-controlled technology is also combined with the Eco-Drive movement: light-powered charging reduces maintenance. 

Reference-level precision, reliability, and daily comfort with an unmistakably CITIZEN technical signature.

Did you know?

What does radio-controlled mean?
The watch receives a reference radio signal and adjusts itself automatically to maintain the correct time.

What is an atomic clock?

It is the official reference for time: the watch synchronizes to this reference.

Does it work everywhere?
It depends on signal coverage and the environment (buildings, interference).
In some areas, reception may be limited.

Daylight saving time, do I have to adjust it manually?

Typically no: many models handle the switch automatically, if supported. Always check the features of the specific model.

Are radio-controlled and GPS the same thing?
No, radio-controlled uses ground-based stations, while GPS uses satellites.
Different technologies, with different coverage and logic.
