By default, the settings on the watch are optimized for battery life and performance. This means the Always On display setting is set to "off" out of the box.

Always On Behavior

You can turn your wrist toward your body, tap the touchscreen, or press a button to wake the watch at anytime it has timed out. 

On the Watch Face When Enabled

This is the behavior to expect when using Always On, and the watch is showing the watch face.

• On-Wrist - The display will dim after your selected Timeout setting (4/8/15 seconds). 
• Off-Wrist - The display will dim after your selected Timeout setting (4/8/15 seconds). The display will then timeout after 5 seconds of no movement.

• Off-Wrist - The display will dim after your selected Timeout setting (4/8/15 seconds). The display will timeout after 2 minutes. 

When Disabled
