John Hardwood invented the first self-winding wristwatch, more commonly known today as the automatic watch, in 1924. His invention employed the “hammer” movement to automatically wind a watch. In 1966, Georges Delessert, Eric Jaccard, and Felipe Lang developed a self-winding watch movement, improving on Hardwood's design, wherein the movement is caused by “a winding mass in the form of an annular segment that swings on ball bearings about its center of curvature”. This lead to the modern-day watches with a weight that swings in 360 degrees, allowing winding in both directions just by the natural movement of the wearer.
