Timex came up with a winning idea with the Indiglo watch. With a blue-green light for illumination, the watch face is easy to read in the dark, but the nature of the light does not harm your night vision. Available in a traditional clock-face style or a more advanced digital model, the first thing you need to know is how to set your timex indiglo.

Pinch the winding knob on the right side of the watch between your thumb and forefinger.

Pull the knob out from the watch slowly until it clicks into the first position.

Turn the knob to move the hour and minute hand to set the time. Move the knob clockwise to move the settings forward and counterclockwise to move them backwards.

Pull the knob out further until it clicks into the second position. In the second position (the one furthest from the face), turn the knob to set the calendar, if your Indiglo has one. Turn the knob clockwise to move the settings forward and counterclockwise to move them backward. Push the knob back in to the watch face when you are done.

Press the button on the lower right side of your Indiglo watch to unlock the mode function of the watch.

Press the button on the lower left side to move through the modes. Each time you are in a mode, the digital display will flash. For example, when the time display begins to flash, you are in the correct mode to set the time.

Change the time (or date) by pressing the button on the upper right side to advance the numbers or the button on the left side to move the numbers down. When you do this, you will be changing the first set of numbers (the hour or month, for instance); to change the minutes, press the button on the right side of the face until the second set of numbers is flashing and begin the process again.

Press the button on the lower left side of the watch to save your settings. The button on the upper left side of the watch is not used in this process--it is the switch to turn on your Indiglo light.
