The wristwatch was originally called a wristlet and was primarily worn by women. During the 19th century, most gentlemen preferred to carry the pocket watch, which was considered more masculine. The wristwatch gained popularity with the military during the Boer War, as British officers used these timepieces to coordinate attacks. As the wristwatch gained popularity with both sexes, watchmaking became a popular and lucrative occupation. While the industry continues to evolve, there are certain standards that still apply to watchmaking nomenclature.
The watch case is the outer covering, generally made of metal, which is designed to protect the inner workings from contamination.
The watch crown is a knob that is affixed to a pin that fits through the case and is used to wind the mainspring or to set the time of mechanical watches. On electronic models, the crown may be simply ornamental.
The watch crystal is a piece of glass, crystal or some other transparent covering that fits over the watch face to protect the hands from dirt, dust or other trauma.
The section of the watch case where the watch movement is situated is called the middle.
The watch bezel is a rim that encircles the crystal and holds it in place.
