A watch is a portable timepiece intended to be carried or worn by a person. It is designed to keep a consistent movement despite the motions caused by the person's activities. A wristwatch is designed to be worn around the wrist , attached by a watch strap or other type of bracelet , including metal bands, leather straps, or any other kind of bracelet. A pocket watch is designed for a person to carry in a pocket , often attached to a chain. Watches were developed in the 17th century from spring-powered clocks, which appeared as early as the 14th century. During most of its history the watch was a mechanical device, driven by clockwork , powered by winding a mainspring , and keeping time with an oscillating balance wheel. These are called mechanical watches. By the s the quartz watch had taken over most of the market from the mechanical watch. Historically, this is called the quartz revolution also known as quartz crisis in Switzerland. They generally incorporate timekeeping functions, but these are only a small subset of the smartwatch's facilities. In general, modern watches often display the day, date, month, and year. For mechanical watches, various extra features called " complications ", such as moon-phase displays and the different types of tourbillon , are sometimes included. Furthermore, some modern watches like smart watches even incorporate calculators , GPS [6] and Bluetooth technology or have heart-rate monitoring capabilities, and some of them use radio clock technology to regularly correct the time. Most watches that are used mainly for timekeeping have quartz movements. However, expensive collectible watches, valued more for their elaborate craftsmanship, aesthetic appeal, and glamorous design than for simple timekeeping, often have traditional mechanical movements, despite being less accurate and more expensive than their electronic counterparts. Watches evolved from portable spring-driven clocks, which first appeared in 15th-century Europe.
