A wristwatch is a portable timekeeping device designed to be worn on the wrist. It typically consists of a case that houses the movement, a dial to display the time, and a strap or bracelet for securing it to the wrist. Wristwatches can be powered by various mechanisms, including mechanical, quartz, or digital technology. In addition to telling time, many wristwatches offer additional features, such as chronographs, alarms, and water resistance. They come in various styles and materials, catering to different preferences and occasions, from casual to formal wear. Some people collect wristwatches as a hobby, appreciating their craftsmanship and design.
