wallclock

A wall clock, sometimes written wallclock, is a clock that is mounted on a wall to display time for a room. It is typically designed for quick readability and can be analog or digital, though analog models with hands on a dial remain common in homes and offices.

Movement and power: Most contemporary wall clocks use a quartz movement powered by a battery, offering high accuracy and low maintenance. Prior to quartz, many wall clocks used mechanical movements—spring-driven with a pendulum or balance wheel. Electric wall clocks can use synchronous motors tied to the electrical grid, though battery-powered models are prevalent today.

Display and features: Common examples have a 12-hour dial with hour and minute hands and often a second hand. Many clocks include a chime or strike mechanism that sounds on the hour or quarter hours. More recent models may be radio-controlled or networked to synchronize with national time signals, ensuring precise time without manual adjustment.

Design and installation: Wall clocks vary in size from compact to large statement pieces. Materials include wood, metal, glass, and plastic, with finishes ranging from traditional to contemporary. Installation requires secure mounting to a wall, typically with a mounting bracket or screws; weight considerations are important for larger clocks.

History and use: After the invention of pendulum clocks in the 17th century, wall clocks became widespread in households and public spaces during the 18th and 19th centuries. They continue to serve both practical timekeeping and decorative roles in homes, schools, offices, and public areas.
