To maximize battery life and increase screen longevity, D2 Air and D2 Air X10 watches default to a setting that will turn off the screen while in smartwatch and activity modes. Pressing a button, double-tapping the screen, or raising your wrist will turn on the display. D2 series watches also offer Always On mode for smartwatch use and/or during activities. Always On mode will decrease the time between battery recharging and enabling the feature will provide a lower fidelity where the display will not be as sharp. Additionally, the watch must be worn on the wrist for the Always On feature to work. When off the wrist, the display will still turn off.
NOTE: The Always On and Gesture settings are disabled during your sleep window to prevent the display from turning on while you are asleep. For information about the sleep window, please see: Setting Sleep and Wake Window Times in Garmin Connect.
You can enable Always On mode for smartwatch mode (Not During Activity) and/or when doing timed activities (During Activity). Select your watch model below to reveal instructions.
