A wall clock is a timekeeping device designed to be mounted on a wall. It typically features a circular face with numbers or markers that indicate the hours and minutes. Most wall clocks use either quartz movement, which is powered by a battery, or mechanical movement, which relies on gears and weights. They come in various styles, sizes, and materials, making them suitable for different home or office environments. Wall clocks serve both functional and decorative purposes. They help people keep track of time in a convenient way, while also enhancing the aesthetic of a room. Some wall clocks may include additional features, such as alarms, thermometers, or hygrometers, providing extra information beyond just the time.
