This knob can be pulled out to set the time and date on the watch. The crown is the little dial knob usually on the right side of the watch. This will interfere with the automatic winding mechanisms, which are built for regular, everyday arm movement. Avoid wearing watch when playing sports that require continuous hand or arm movement, such as tennis, squash or basketball.

If you are sick and laid up in bed, your watch may wind down since it’s not getting regular everyday movement. People who are not very active, such as elderly people or those confined to bed, may need to wind their automatic watches with more frequency.Typically, automatic watches store energy for up to 48 hours so that they continue working without needing additional winding.Automatic watches are built to respond to average, everyday movement in order to keep them working. This doesn’t mean, however, that your arm needs to be in constant motion. If you wear your watch and keep your arm in regular movement, this should be enough to keep the rotor moving and winding up the mainspring. If the watch is not being moved in regular, everyday motion, the mainspring’s energy winds down. This stores energy in the mainspring so that the watch continues ticking. When the rotor moves, it moves the gears which, in turn, winds the mainspring. The oscillating rotor is attached to gears inside the watch that are in turn attached to the mainspring. The automatic watch is built with an oscillating metal weight, or rotor, that tracks movement.
