Watch winder box. When Perrelet and Hardwood –the founding fathers of what we know now as “self-winding” watch–thought that mechanical watch system that was used at his time was not too reliable and practical because people had to open their watch case to wind and set it. He then made a new discovery using children’s seesaw as an inspiration for the kinetic energy based design. At that time, he and most people probably thought job is already well done, and time will be kept at its best with no delay, until the quartz mechanism is found or until people decided to own more than one “self-winding” watch
If you own more than 4 self-winding watches you probably unconciously already rank your favorite watch in your mind, resulting in most worn item and less worn item, just like people and their favorites clothes, some clothes will always be worn more often than the others. It will not be a problem if all your watches are only exclusively tell time, you can always manually turn the winder by your hands. But what if you bought a mechanical watch that is able to show the date, month, years, even moon phase? Manually wind, adjust dan reset that kind of mechanical watch will be such a burdensome hassle. How are you gonna check if full moon is approaching and it’s time to avoid werewolf at all cost?
A watch winder, or maybe some watch winders can solve all the problems above. A watch winder will make sure your self-winding watches keep running even though it’s rarely on your wrist hence not getting the kinetic kick it needs. Most watch winders are pricey, double watch winders who can fit two watches will cost you more than a hundred dollar, the good quality watch winders who isn’t noisy and long lasting can cost around 300-400 USD but it will be a better choice that buying the cheaper ones that has loud buzzing sound that will annoy you. But again, your money your rule! So if you think your collection of mechanical watches deserve that expensive energy to stay “healthy” then just go ahead and get yourself a good quality watch winder.
