The Timex Ironman Solar 50-Lap Dual Tech watch is unique because it is powered by solar energy. The watch battery recharges with light. Other functions of the watch include a digital or analogue display, time and date, chronograph, countdown timer, alarm, optional hourly chime and an Indiglo night-light. The Ironman Solar 50-Lap watch can time up to 100 laps and store 50 laps. Because of the solar technology, you may need to troubleshoot some issues with this watch that you don't with a regular Ironman watch.

Skill level:


  1. 1

    Position the watch so your sleeve does not cover the watch face if your watch does not seem to be charging properly when you are out in the light.

  2. 2

    Store your Ironman watch where it is exposed to light if your solar battery seems to run down quickly.

  3. 3

    Press any button or place your watch in sunlight if the display shuts off. The Ironman Solar 50-Lap shuts down the display after one month of no exposure to light.

  4. 4

    Replace the battery if it fails to charge even in direct sunlight.

Tips and warnings

  • If the battery becomes fully depleted, it can recharge in a few days if you expose the watch face to direct sunlight.
  • You can charge the solar battery with any light, but direct sunlight works best. Sunlight filtered through windows is better than indoor lighting.
  • The battery icon shows your current battery level. If the icon is all black, the battery is fully charged. If it is half black and half white, the battery is half empty. If the icon is all white the battery is almost depleted. If the icon is half white and blinking, the battery is low, but charging. If the icon is half black and blinking, the battery is half empty, but charging.
  • You shorten the battery life the more you use the audible alarm and the night-light.
