Smartphone Link

Linking the watch to a smartphone provides access to the correct time,
not only in the current location but over 300 cities around the world.
Alarm setting and control over various other functions
from the smartphone enhance operability to an unprecedented high level.

Automatic Time Adjustment

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.

Accurate Time System

The watch is reset regularly 4 times a day*1 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*2 when crossing between time zones. The precise time in the current location is displayed instantly with DST (daylight saving time) taken into account.
