INDIGLO Night Light
The Indiglo night light uniformly lights the surface of the watch dial using patented electroluminescent lighting technology.
The NIGHT-MODE feature makes viewing your watch screen in low-light conditions even easier: simply hold down the INDIGLO button for 3 seconds to activate and the watch will automatically illuminate with any button pressed.
Do you ever get so engrossed in your workout, you can't remember if you're supposed to be starting a sprint or jog interval? Interval training routines are designed to vary the intensity of a workout with alternating segments of easy, moderate and hard exertion. Set your Timex Ironman interval timers, and alerts will notify when you need to change the pace. A classic beginner interval workout is the run/walk. For example, after warming up, start your interval timer and run for 1 minute. When you hear an alert, walk for 3 minutes. At the next alert, repeat the series again. Interval training has been shown to improve speed and endurance more effectively than traditional steady-state workouts.
Your watch is water resistant if it has the wave symbol etched into the back of the case. Water resistance is measured and rated by depth in meters. The tests are made by subjecting the watches to water pressure (see table below, p.s.i.a. = pounds per square inch absolute).
||30 meters = 98.4 feet
||50 meters = 164 feet
||100 meters = 328 feet
||200 meters = 656 feet
The watches will withstand water pressure up to their respective ratings as long as the lens or crystal, crown or push buttons and case remain intact.
