Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly.
ξThis watch is designed to pick up the time calibration signals transmitted in Germany (Mainflingen), England (Anthorn), the United States (Fort Collins), China (Shangqiu), and Japan (Fukushima, Fukuoka/ Saga).
ξSee the information under “Signal Reception Troubleshooting” (page
Current Time Setting
This watch adjusts its time setting automatically in accordance with a time calibration signal. You also can perform a manual procedure to set the time and date, when necessary.
ξThe first thing you should do after purchasing this watch is to specify your Home City (the city where you normally will use the watch). For more information, see “To specify your Home City” on page
ξWhen using the watch outside the areas covered by the time signal transmitters, you will have to adjust the current time setting manually as required. See “To set the time and date manually” (page
ξThe North American time calibration signal can be picked up by the watch while in North America. The term “North America” in this manual refers to the area that consists of Canada, the continental United States, and Mexico.
ξUsing this watch in a country covered by a time calibration signal that is different from the countries it supports may result in incorrect time indication due to local application of summer time, etc.

ξSee the maps under “Approximate Reception Ranges” (page
Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal: auto receive and manual receive.
ξAuto Receive
With auto receive, the watch receives the time calibration signal automatically up to six times a day (Þ ve times for the China signal). When any auto receive is successful, remaining auto receive operations are not performed. For more information, see ÒAbout Auto ReceiveÓ (page
ξManual Receive
Manual receive lets you start a time calibration receive operation with the press of a button. For more information, see ÒTo perform manual receiveÓ (page
Important!
ξWhen getting ready to receive the time calibration signal, position the watch as shown in the nearby illustration, with its 12 o’clock side pointing towards a window. This watch is designed to receive a time calibration signal late at night. Because of this, you should place the watch near a window as shown in the illustration when you take it off at night. Make sure there are no metal objects nearby.

ξSignal reception normally is better at night than during the day.
ξTime calibration signal reception takes from two to seven minutes, but in some cases it can take as long as 14 minutes. Take care that you do not perform any button operations or move the watch during this time.
ξThe time calibration signal the watch will attempt to pick up depends on its current Home City code setting as shown below.
Home City Code | Transmitter | Frequency | |
LON, PAR, BER, ATH, LIS, MAD, | Anthorn (England) | 60.0 kHz | |
ROM, STO, MOW* | Mainflingen (Germany) | 77.5 kHz | |

*The areas covered by the HNL, ANC, and MOW city codes are quite far from the time calibration signal transmitters, and so certain conditions may cause problems with signal reception.
ξCalibration signal reception is disabled while a countdown timer operation is in progress.
