Specifications

3-wave radio-controlled wall clock. CITIZEN Three Wave M821 radio-controlled wall clock [4my821-019]

It also catches AM radio time signals, expanding the range of use.

The Three Wave series is a radio-controlled clock system that receives time in three ways: the 40/60 kHz Japan Standard Time signal and the AM radio time signal (beep beep beep beep).

Even in places where it was previously difficult to receive the Japan Standard Time signal alone, the reception range has been expanded by receiving AM radio time signals, which are closer to the transmitter and have a stronger transmission output than the Japan Standard Time signal.

Easy to use and no hassle

There is no need to manually set the time; the watch automatically displays the approximate time stored in memory as soon as the battery is inserted, making it easy for anyone to set (approximately 3 minutes).

After that, there are three ways to receive and correct the time.

Battery life approximately 10 years

The battery has a long life of 10 years to minimize the need for battery replacement.

Note 1) Reception may be impossible in windowless buildings where AM radio reception is poor, in the basement of a building, or in extremely noisy locations.

Note 2) You can use it right away, but if you are receiving AM radio time signals, it will take a long time to correct the time as the time signals are accurately received and evaluated on the hour .

Note 3) Please use batteries that are guaranteed to have a recommended usage period of 5 years according to JIS standards.
