A watch or watch is a timepiece worn on the human wrist with an ever-increasing display of time. The main use of watches is to show the time at a certain time and calculate the time span between two events at different times. Watches generally have three kinds of hands, namely the short hour hand, the longer minute hand and the longest seconds hand. Shifts in the appointment of the hands occur every 60 scales, starting from the second hand to the minute hand and from the minute hand to the hour hand. Watches were first introduced in the 16th century. At that time all watches and other timepieces used hand-winding machines. The oldest known watch is that of the Queen of England Elizabeth I, which was made by Robert Dudley in 1571. From the 16th century to the early 20th century, wristwatches were worn only by women, while men wore pocket watches. The dominance of mechanical watches for centuries The century with all its beauty, complexity, and luxury, was finally disturbed by the presence of an electric wristwatch which was first introduced in 1957 in Lancaster, Pennsylvania, United States by the Hamilton Watch Company. Research on the electric watch actually started in 1946. The existence of electric watches did not last long, until Seiko from Japan introduced the world's first quartz (battery) driven wristwatch, the Seiko Astron 35SQ in 1969. The birth of this quartz watch was recognized by the IEEE (Institute of Electrical and Electronics Engineers) for entered into the list of milestones in the development of world electrical engineering. It was this type of watch that then really undermined the hegemony of the Swiss mechanical watch industry. Quartz watches dominate the market, are used by other brands, and are the beginning of a global change in the watch industry. Watches that were originally produced in limited and exclusive quantities, turned into mass production with a more affordable selling price.
