Mechanical watches evolved in Europe in the 17th century from spring powered clocks, which appeared in the 15th century. [citation needed] Because the mainspring provides an uneven source of power (its torque steadily decreases as the spring unwinds), watches from the early 16th century to the early 19th century featured a chain-driven fusee which served to regulate the torque output of the mainspring throughout its winding. Either way, automatic winding dates back several centuries. High Quality 17 Jewels 6498 Hand Winding ST3621 Mechanical Movement for Watch. Cortebert Cal.
