About the AMOLED Display
By default, the watch settings are optimized for battery life and performance (Tips for Maximizing the Battery
Life, page 117).
Image persistence, or pixel "burn-in," is normal behavior for AMOLED devices. To extend the display life, you
should avoid displaying static images at high brightness levels for long time periods. To minimize burn-in, the
D2 Mach 1 display turns off after the selected timeout (Changing the Screen Settings, page 110). You can turn
your wrist toward your body, double-tap the touchscreen, or press a button to wake the watch.
