Even the most modest mechanical watch houses a host of components in what can only be described as miniature feats of engineering excellence and creative daring. Yet one of its most critically important components is also one of its least hailed. That often overlooked component is the mainspring, which is unwarranted given how important it is to any mechanical watch. After all, the ‘magic coil’ that is a mainspring is at the heart of any mechanical watch.
There is a reason why Bloomberg referred to the mainspring as, “Watchmaking’s Most Essential and Underappreciated Component” in a February 2020 article. We here at LIV Watches are so enamored of mechanical watches that we thought it only right to pay homage to this most deserving component. This article will provide some insight into the brief history and basic mechanics of the mainspring. It will also look into some of the maintenance aspects thereof, as well as a few of the typical myths relating to mainsprings.
