When this function is activated, a slight turn of the wrist is enough to illuminate the background of the watch. Energy-saving: The Full Auto Illuminator only works in dark environments. Whether in Europe, North America and Japan or in large parts of Canada, Central America and China - once the watch is set to the local time zone, it receives the corresponding radio signal and always displays the exact time. In many countries, it also independently sets summer and winter time. The watch receives the local radio signal and sets itself automatically to always show the correct time. The first digital wristwatches appeared as early as the 1970s. They have now become firmly established and offer an interesting alternative to classic analogue watches. By means of an LCD display, the digital watch allows you to read off the time conveniently, accurate to the minute. In addition, many models have sophisticated additional functions, such as a date display or a stopwatch function. The watch is a practical accessory for everyday life, with which you always have the time in view.
