Wrist Wach
Simple Overview
Today, the most common type of watch is the wristwatch worn on the wrist and fastened with a watchband made of leather, nylon or other plastics (then called strap), metal links (called bracelet) or even ceramic. Before the inexpensive miniaturization that became possible in the 20th century, most watches were pocket watches, which had covers and were carried separately, often in a pocket and attached to a watch chain or fob.

Most inexpensive and medium-priced watches used mainly for timekeeping are electronic watches with quartz movements. Expensive, collectible watches valued more for their workmanship and aesthetic appeal than for simple timekeeping often have purely mechanical movements and are powered by springs, even though mechanical movements are many times less accurate than quartz movements. The most accurate watches have radio-controlled movements that are miniaturized, portable versions of radio clocks.
