Why are the sunrise and sunset times I find in a newspaper or on the web different from those indicated by the watch?

The sunrise and sunset times calculated by the watch are based on GPS latitude and longitude of your current location, and so they may not exactly match the times for the location used for determining the times shown in a newspaper or website. Also note that calculations always assume a level horizon, and local topography is not taken into consideration. Calculation results include error, which increases at higher latitudes.
* If there is no communication with the phone, the watch will not be able to perform calculations correctly because it cannot obtain GPS values.
