what are the different types of clocks?
Sundial, hourglass, water clocks, striking clock, watches, pendulum clock, and electric clock
Clock
 A sundial shows the time by displaying the position of a shadow on a flat surface. There is a range of duration timers, a well-known example being the hourglass. Water clocks, along with the sundials, are possibly the oldest time-measuring instruments. A major advance occurred with the invention of the verge escapement, which made possible the first mechanical clocks around 1300 in Europe, which kept time with oscillating timekeepers like balance wheels.

Traditionally in horology, the term "clock" was used for a striking clock, while a clock that did not strike the hours audibly was called a timepiece. In general usage today, a "clock" refers to any device for measuring and displaying the time. Watches and other timepieces that can be carried on one's person are often distinguished from clocks.
Spring-driven clocks appeared during the 15th century. During the 15th and 16th centuries, clockmaking flourished. The next development in accuracy occurred after 1656 with the invention of th
who invented the first mechanical clock in 1300 Catholic monks which of the earliest civilizations used timekeeping devices? Hunter-gatherers, Prehistoric Europe, Mesoamericans, etc why did the monks invent the clock? To regulate daily prayer- and work-schedules strictly and to ensure accuracy can you give me examples of timekeeping devices? Astronomical bodies, sticks and bones to track the phases of the moon or the seasons, Stone circles, sexagesimal timekeeping, and vigesimal counting system name some of the innovations during the medieval period Clock, wristwatches, Clock of the Long Now, mechanical clock, and pendulum clock did ancient egypt use timekeeping devices? Yes, Shadow clocks and Sundials what about greece? They used water clocks, or clepsydrae, and water-based alarm clock name some of the innovations during the pre-modern period Mechanical clocks and pendulum clock is it possible to keep track of time underwater? Yes, by Marine chronometers how did the persians keep track of time? By using water clocks what device did the chinese invent to keep track of time? Outflow and inflow clepsydra is there an industry now that deals specifically with time keeping devices? Yes, clock and watch-making industry who invented the wristwatch? UNANSWERABLE

Clock [SEP] Introduction
A clock is a device used to measure, keep, and indicate time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units: the day, the lunar month, and the year. Devices operating on several physical processes have been used over the millennia. Some predecessors to the modern clock may be considered as "clocks" that are based on movement in nature: A sundial shows the time by displaying the position of a shadow on a flat surface. There is a range of duration timers, a well-known example being the hourglass.
