A Look Inside the Movement: How A Self-Winding Watch Works
Throughout the ages, we’ve developed many ways to keep track of time. From sundials to mechanical watches, we’ve come a long way. Today, most mechanical watches are self-winding, but how does a self-winding watch work? Read on to find out.
In order to understand how a self-winding watch works, you need to know how a manual watch works—that is, one you need to wind yourself. All mechanical watches are powered by a spring called the “mainspring,” which turns the gears and ultimately the hands. Manual watches must be wound daily in order for the mainspring to have enough energy to turn the gears and hands all day.
A self-winding watch is designed much like a manual watch, but with the addition of an “eccentric weight.” As you move your arm throughout the day—whether by walking, checking the time, etc.—the eccentric weight pivots inside the watch. This pivoting motion slowly and automatically winds the mainspring and powers the watch so you don’t have to bother with winding it yourself.
These days, the vast majority of mechanical watches are self-winding. While it may be fun to own an old-time manual watch, a self-winding watch is much more practical and easy to use. Could you imagine winding your watch every day to get it to work? If you forget one day, your watch could run down, and force you to readjust the time—a watch is supposed to keep you on time, not take up your time.
