Now that I have a Rolex, I need a watch winder.
What is a watch winder?
Certain watches do not need to be wound because they wind themselves when they are moving on your arm throughout the day. When you don’t wear those watches they tend to stop, so a watch winder, which simulates that natural motion keeps automatic watches operating.
The internal parts of automatic watches are designed to follow the pull of gravity. Therefore, they don’t have gears that must be wound with a spring. Instead, their tiny weights get pulled by gravity as you move and swing your arm, so little by little these weights are twisting around both clockwise and counter-clockwise, until your watch is wound up. Watches like this are called automatic or self-winding types, as opposed to quartz, kinetic, or mechanical watches.
