A watch is a small portable clock that displays the time and sometimes the day, date, month and year. In modern times they are usually worn on the wrist with a watch-strap (made of e.g. leather (often synthetic), metal, or nylon), although before the 20th century most were pocket watches, which had covers and were carried separately, often in a pocket, and hooked to a watch chain. Some well known watches are: Rolex, Tissot, Seiko, Breitling, Cartier, Swatch, Omega. Sometimes you can follow auctions selling those branded watches for very attractive prices. Many collectors worldwide are following those auctions to buy for their collection or to sell it further and make some profit.
Current watches are often digital watches, using a piezoelectric crystal, usually quartz, as an oscillator (see quartz clock). Mechanical timepieces are still used, usually powered by a spring wound regularly by the user. The invention of "Automatic" or "Self-Winding" watches allowed for a constant winding without special action from the wearer: it works by an eccentric weight, called a winding rotor, that rotates to the movement of the wearer's body. The back-and-forth motion of the winding rotor couples to a ratchet to automatically wind the watch. Watches may be collectible; they are often made of precious metals, and can be considered an article of jewelry. |
