Compass
The watch has a 3-axis compass with automatic calibration. The compass features and appearance change depending on your activity, whether GPS is enabled, and whether you are navigating to a destination. You can change the compass settings manually (Compass Settings). You can view the compass from the controls menu (Controls), glances list (Glances), or a data screen during an activity (Customizing the Data Screens).
