Keep your sports training focused with the full-sized Timex Men's T53151 Ironman Traditional 30-Lap multi-function, performance sport digital watch, which features a 30-lap memory recall, all-day Indiglo® display feature, top pusher for easy access to lap and split times, black resin strap, and black resin top ring within a dark gray case. Sport timing features include a 100-hour chronograph with lap or split option, 24-hour countdown timer with countdown/stop and countdown/repeat functions, and 99-lap counter. It also features daily/weekday/weekend alarms with 5-minute back-up, two time zones, built-in setting reminders, and water resistance to 330 feet (100 meters).

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. The buttons should not be depressed while under water.
