What does it mean when a clock is overwound?
That is an interesting question. Often, one sees clocks advertised on eBay and elsewhere as “not running, probably over-wound.” The fact is, there is no way to over-wind a clock. Specifically, if a clock is wound fully, eventually the winding key will no longer turn. At this point, the spring is tight and capable of delivering the most power to the clock. This will not cause the clock to stop. When the condition of a clock is described as “over-wound,” there is always another underlying cause for why the clock will not run. The clock ends up fully wound because winding is the first thing we try when a clock has stopped. It is difficult to determine the cause without inspecting the movement.
