The second hand , frequently called second hand one , is a movable part which designates the second being on the dial of a clock mechanism.
It is a less frequent needle than the hour hand and the minute hand , which are indispensable. When it exists, it is usually the largest of the three and can have a specific color.
The second hand makes a turn on itself in a minute . It therefore travels at 21 600 ° per hour and 518 400 ° per day .
