There are two types of mechanical watches, manual winding and automatic watches. Manual winding watches need to be wounded to keep the movement running. Meanwhile, automatic watches get kinetic energy to move their movements through the swings of your hands when using it.
For automatic watches, it may be easy enough to stay it on, you just have to move them around and use them often. In addition, there’s also a power reserve in automatic watches, you need to keep an eye on it, so you know when your watch will run out of energy.
Meanwhile, for manual winding watches there are so many questions that raise questions, like how often you need to winding it? Just like automatic watches, manual winding watches also have a power reserve to keep the energy flowing.
Power reserve is a feature where a watch movement saves the energy obtained. The spare time on each watch varies between 38-240 hours, and it is very important for you to know the power reserve of your watch before you purchase it, as it can make a huge difference to how you like wearing it.
The point of seeing how long the power reserve of your watch is to let you know how long the watch can store energy from the first time you wound it up until the movement stops running.
So, how often you have to wound a manual winding watch can be seen from how long the power reserve of the watch is. If your watch has a power reserve of up to 50 hours, that means you have to wound your watch once in two days.
Then, for manual winding watches, watch manufacturer experts recommend turning the crown 30-40 times on a watch movement that has run out of energy to return it to full energy. As for automatic watches, you just need to shake it a few times or use it on your wrist within 8-10 hours to get the energy for your movement.
Another question that often arises is, will the manual winding watch be damaged if it is rotated excessively? The answer is no. Because all mechanical watches have a mechanism in the movement that removes the winding gear from the mainspring when it is fully rotated. However, it is still a good idea to follow the advice to wind it only 30-40 times.
On some manual winding watches, there is a system that you will begin to feel some resistance once the watch is fully wound. Then, there is also a manual winding watch which, if fully wound, it’ll make a faint ‘click’ sound.
