#tbt 1976 Girard-Perregaux Casquette ad. The new face of time!
In the 1970s, the quartz technology, using the electric energy of a battery enabled the development of a new type of display - LED display (diodes) and then liquid crystal display. The energy consumption of the LED was such that to avoid the battery running down too quickly, the display was turned off. To read the time, it was necessary to press a button to illuminate the LED and to be able to see the numbers.
