Overview

The watch's time and day settings can be
configured in accordance with a received time
calibration signal.

a phone even once for time adjustment
during the previous day while

it will automatically try to receive a time
calibration signal.

reception is supported are limited.

time calibration signal reception is not
possible, connect with a phone to
adjust time and day settings.
