For centuries they have measured our time (from the shadow of the sundial to the dial on the wrist): recognise the wristwatch, pocket watch, wall clock, grandfather clock, cuckoo clock, hourglass, sundial, alarm clock, stopwatch, digital watch, tower clock and egg timer by their shape. Good to know: The wristwatch is worn on the wrist and shows the time on a small dial. It replaced the pocket watch in daily life. The pocket watch is carried on a chain in a waistcoat pocket. A hinged cover often protects the dial. The wall clock hangs clearly visible on the wall. It is a classic in kitchen and office. The grandfather clock is a tall, free-standing clock case with a pendulum. Its striking mechanism announces the full hours. From the cuckoo clock a wooden cuckoo calls on the hour. It traditionally comes from the Black Forest. The hourglass measures time by sand trickling between two glass bulbs. To restart it you simply turn it over. The sundial tells time from the shadow of a rod in sunlight.
