General Reference for Receiving Areas
This watch is provided with an automatic tuning feature that automatically selects the station to
be used for reception of standard time radio waves. A general reference for the areas where the
watch can receive standard time radio waves is as follows. However, reception status in these
areas may vary due to the times of sunrise and sunset, seasonal changes, weather conditions
(presence of lightning, etc.). Since this map only provides a general reference of the standard
receiving areas, it may not apply in some particular locations even within the range shown in
the map.
Radio wave transmitter station Standard time radio wave
Mt. Ohtakadoya standard JJY
radio wave transmitter station (long-wave standard
(Fukushima Station) radio wave)
Mt. Hagane standard radio JJY
wave transmitter station (long-wave standard
(Kyushu Station) radio wave)
Although the standard time radio waves used this watch are transmitted continuously nearly 24
hours a day, there are times when transmission is interrupted for maintenance, inspections and
so forth. This watch will continue to run at an accuracy of within ±15 seconds per month even
when standard time radio waves are unable to be received. You can confirm the transmission
status of standard time radio waves by viewing our web site or contacting the Citizen
Consumer Help Desk.
