This watch can receive standard time radio waves broadcast from Japan (two transmitters), the USA, Europe
(Germany) and China.
The standard time radio wave to be received can be changed by selecting the city in another region.
The maps show the approximate reception areas. However, note that the radio wave condition could change
due to factors including the weather (such as lightning) and changes in the season or sunrise/sunset time.
The reception area on the map is only guideline, and it may be difficult to receive the radio signal even
within the areas indicated on the map.
