">naval parlance, watches are a timekeeping convention. The term in general use can mean any period of duty or responsibility, such as a hurricane watch.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.
