The watch is reset regularly 4 times a day by the smartphone to show both home time and world time correctly. You can also reset the watch manually with just a push of a button when crossing between time zones. The precise time in the current location is displayed instantly with DST (daylight saving time) taken into account. Accurate time information (UTC) is acquired by a smartphone from a time server on the Internet. The smartphone then analyzes this time data and its own current positioning data regarding the time zone and DST (daylight saving time) status of the current location and resets the watch to the correct time automatically. Since Wi-Fi communication is also possible, the smartphone can also acquire time information in indoor environments such as airports or subways. The smartphone app can be used to conduct world time city selection. After a city is selected by touch from a world map or a city list containing over 300 cities, the time in the selected city is displayed on an inset dial with DST (daylight saving time) taken into account. Home Time is displayed on the main dial and World Time on the inset dial at 9 o’clock in a 12-hour format. The AM/PM status of the selected city are also displayed. Switching between the two city time displays can be conducted with button operation or using the app. Tough Solar converts light to electric power to support stable operation of multiple functions.
