II. About Automatic Mechanic Watch
A mechanic watch uses a mechanical mechanism to measure the passage of time, as opposed to modern quartz watches which function electronically. It is driven by a spring (called a mainspring) which must be wound periodically. An automatic wind watch is a watch that powered by the swinging of your arms to keep the watch ticking. If you do not wear an automatic watch consistently (for about 8 to 12 hours a day), you can keep the watch powered with a watch winder (a great gift for collectors).
