Timex Women's Q7B781 Calfskin 12mm Black Replacement Watchband

One of the most successful and important features available on many Timex watches is the Indiglo backlight system. Indiglo is a brand name of Indiglo Corporation, solely owned by Timex for licensing purposes. Timex electroluminescent lamps, branded Indiglo, were introduced in 1992 in the Ironman watch line. They were an immediate success. The Indiglo lamp uniformly lights the surface of the Timexs watch dials in a manner that makes the dial read very easily in many different light settings. In some newer watches the Indiglo backlight only lights up the numbers, rather than the entire LCD display, which is achieved by means of a specialized film that inverts the LCD transmissivity.
