“If my watch winds while I wear it, how does it know when it’s fully wound?” It was a question posed to me by a first-time watch owner. While I had a reasonable response at the time - “it just does, don’t worry about it” - my curiosity led me down a path of research to understand the parts that power both modern and vintage watch.

VINTAGE, MANUAL WIND WATCHES

Before looking at the enhancements that prevent over-winding on a modern, automatic watch, it is helpful to first understand the basics. The simplified render below of a watch hairspring highlights the type of coiled spring that exists inside the barrel of any watch movement. This coil spring is attached on the outer side to keep the spring from spinning as it is wound.
