The first watches did not wind automatically. They did not light up with digital numbers, nor did they tell the date or have alarms that could be set. These completely mechanical watches didnt need batteries either, but they did need to be powered somehow. In order to keep on going, a mechanical watch needs to be wound regularly — usually once per day. So why would people today opt for a mechanical watch in this age of inexpensive quartz and digital watches? Its all about aesthetics and an appreciation for the art of watch making.
What Makes a Watch Mechanical?
For a watch to be completely mechanical it must not only run by means of a wound spring and set of gears, but these must be powered by mechanical means. This is different from a quartz watch which also ticks off time by the movement of gears, but keeps those gears moving through the energy of a quartz crystal. With a mechanical watch the energy to move the gears is powered by the winding of the mainspring. When the spring is fully wound on a typical mechanical watch the watch will keep accurate time for about 40 hours. There are more complex mechanical watches that can keep time for much longer with...
