To activate FLIX, put the watch into Night-Mode by pressing and holding the Indiglo night-light button 3 seconds until it beeps. With the watch in Night-Mode, a forward "flick" of the wrist with a sharp "stop" will activate the Indiglo night-light for three seconds. The Indiglo night-light uniformly lights the surface of the watch dial using patented blue electroluminescent lighting technology. It uses less battery power than most other watch illumination systems, enabling your watch battery to last longer.
