Whether training for a 10K race or exercising to lose some of that spare tire, the Timex T5C351 digital watch with integrated heart rate monitor will help you make the most of your training. Timekeeping features include a 100-hour stopwatch, 100-hour countdown timer, display of month/day/date and 24-hour clock, an alarm with 5-minute back-up, and a display with flipping system for easy reading. It also features a double-shot polyurethane strap, a battery life of 3 years, and water resistance to 50 meters.
Heart rate monitoring features include target zones with optional alarms, 5 target zones based on maximum heartbeat, average/peak heart rate data, recovery rate timer, and calories burned. The comfortable heart rate sensor offers FM transmission for a clear signal around exercise equipment, synchronized transmission to prevent crosstalk with other heart rate monitors, and continuous readings even during the most intense activities. Comfortable and lightweight, it has an adjustable elastic chest strap and an owner replaceable battery with a 2-year battery life.
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. The Night Mode feature allows you to illuminate the Indiglo night-light for 3 seconds with any button press, regardless of the mode or function.
