Automatic time adjustment
Utilising the Bluetooth link, your smartphone reconnects with your watch automatically four times a day to check and correct the time. When travelling across time zones, the Smartphone Link means you can display the current local time with one push of a button.
The app allows you to check time-related regulations, such as changes in time zones as well as Daylight Savings Time, and add them to the watch’s internal data.
