Automatic self-winding watches are an evolution of the traditional manual mechanical watch, which required the user to wind the watch every day in order to keep it running. This type of watch was first invented in the 1770s, and it quickly became popular due to its convenience and reliability.
One of the key components of an automatic self-winding watch is the rotor, a weighted disk that rotates with the movement of the wearer's wrist. As the rotor turns, it winds the mainspring, which is the source of power for the watch.
In addition to the rotor, automatic self-winding watches also contain other mechanical components, such as gears, springs, and escapements, which work together to keep time and power the watch's functions.
Automatic self-winding watches are prized for their durability and longevity. Because they are powered by the movement of the wearer's wrist, they do not need to be wound as often as manual mechanical watches. In addition, automatic self-winding watches are typically more accurate than manual mechanical watches.
Despite their many advantages, automatic self-winding watches do have some limitations. They are more expensive than quartz watches, and they require regular maintenance in order to keep them running accurately. In addition, automatic self-winding watches are not as accurate as quartz watches, which use electronic movements that are controlled by a quartz crystal.
Overall, automatic self-winding watches are a convenient and reliable type of mechanical watch that are prized for their durability and accuracy. They are a popular choice for those who appreciate the art and craftsmanship of traditional horology.
