properties
Pointer clocks were originally available as single-hand models , from 1700 multi- hand clocks were developed. As a rule, the longer, thinner hand indicates the minutes and the shorter, thicker hand indicates the hours. A second hand is usually longer and thinner than the minute hand. The longest clock hands in the world in 2013 are located in the tower clock of the Abraj Al Bait Tower with a length of up to 17 meters.
Clock hands are perforated at the end located in the middle of the clock and mounted on a guide rod. At the bottom the hour hand and then the minute hand, covered with a small plate so that they cannot rise up and jump out. They have a little leeway so that they can move easily across the dial and you can change their position when setting the clock with the help of a setting wheel.
The shapes and designs of watch hands are varied, with varying finissages . Only a few classic pointer shapes and variants are listed below:
