Watch winder is a device which can store two or more self winding automatic mechanical watches. For those people who do not wear the automatic watches daily, the watch winder is very useful. The main advantage of these kinds of watches is that they keep on working for a long time. We all know that the watches are made up of quartz. The watch keeps on working unless and until the battery reaches the end of its life. For the self winding watches the life of the battery is more than a decade. Hence we can see that the watch keeps on working for a very long time without any disturbance.
Let's learn the description in few points:
The Swiss watchmaker Abraham-Louis Perrelet discovered a self-winding mechanism in 1770 for different kind of watches especially the pocket watches. It worked on the same principle as a modern pedometer, and was planned to wind as the owner walked, using an oscillating weight inside the large watch that moved up and down. The Geneva Society of Arts reported in 1776 that if you walk for 15 minutes then it is sufficient to wind the watch sufficiently for eight days, and the following year reported that it was selling well.
Perrelet sold some of his watches to a modern watch making luminary, Abraham-Louis Breguet around 1780 who enhanced upon the device in his own version of the plan, calling his watches "perpetuelles" the French word for perpetual. They did not work consistently and Breguet finally blocked producing them around 1800.
3. Bumper Wrist Watches
Self winding mechanisms were more flourishing in wristwatches because the rotor could function every time the owner moved his or her arm. The first version did not appear until after World War 1, when wristwatches became trendy. It was invented by a watch repairer from the Isle of Man named John Harwood in 1923, who took out a UK patent with his financial backer, Harry Cutts, on 7 July 1923, and a matching Swiss patent on 16 October 1923. The Harwood system used a pivoting weight which swung as the wearer moved, and which in turn wound the mainspring. The ratchet device only wound the mainspring when moving in one direction. The weight didn't rotate a full 360°; spring bumpers limited its swing to about 180°, to persuade a back and forth motion. This early type of self-winding mechanism is now referred to as a 'hammer' or 'bumper'.
This was a brief description in regard to watch winders. It was definitely one of the most useful inventions and can prove to be quite useful in daily life, as one does not have to go through the hassles of manually winding a watch, or changing the battery, when it runs out. So, a fifteen minutes walk is enough to keep your watch running for 15 days.
