Nowadays, many of the mechanical watches are no longer powered by batteries. Instead, newer technology allows watches to be powered by kinetic movement, which works by generating energy by simply moving the arm. This basically provides the same accuracy of quartz movement without changing the battery and can usually last several decades. The more arm movement is made, the more energy is stored in their electrical generator or rechargeable battery. Frequent arm movements may power the watch either overnight or could extend up to 2 days depending on the watch. This allows you to take it off while letting it still run on its own. So when you go to sleep, it should be safe to put on as long as you wear it again when you wake up.

Watch winders are devices that move in a circular motion so that any placed watch can benefit from the movements of human motion by the emulated speed of the rotation. This also benefits any watches that have extra features like moon phases, perpetual calendars, and other complex complications. Watch winders are usually expensive, but if you really need one, you should take a look at the different kinds of watch winders to see what is best for you with the budget that you have. Depending on the style and functionality, watch winders can cost ranging from $200 to a whopping $8000.This is because manufacturers produce watch winders in very limited quantities and there are only a few manufacturers that produce them.
