An automatic movement, also known as a self-winding movement, is a type of mechanical watch movement powered by the natural motion of the wearer’s wrist. This innovation revolutionized the watchmaking industry, transforming traditional timepieces into accessible, efficient, and highly precise instruments. No longer confined to manual winding, automatic movements marked a new era in horology, elevating mechanical watches to greater heights.
How Do Automatic Movements Work?
The mechanism of an automatic watch operates through a rotor—an oscillating weight that rotates with wrist movement. This rotation winds the mainspring, storing energy to power the watch. The concept dates back to the 1770s when Swiss watchmaker Abraham-Louis Perrelet pioneered the first self-winding mechanism, designed to utilize motion to wind the mainspring. Later, watchmakers like Hubert Sarton refined this technology, leading to its eventual adoption in wristwatches after World War I.
The Intricate Mechanism
A typical automatic movement comprises over 70 intricately engineered components. The stored energy in the mainspring is transferred through the gear train to the escapement, which regulates timekeeping. This complex process ensures precision while offering the convenience of uninterrupted operation as long as the watch is worn regularly.
