The classic first questions about how an automatic watch works are: What kind of energy do these watches keep going? Do automatic watches need batteries? And: does the automatic watch have to be wound manually?
To clarify these questions, we offer you a brief technical and easy-to-understand introduction to the topic: How does an automatic watch work?
The automatic watch – a top product in micromechanics!
This watch converts movement from the wearer’s arm to elevator energy. The mechanical path is as follows: The continuous arm movements exert a torque on the rotor of the watch. The rotor, which is supported in the clock by means of a ball, remains standing in space because it is subject to the physical laws of inertia and gravity.
The torque transfers the force to the winding mechanism. So the tension spring is continuously wound by the natural hand or arm movements of the wearer. For this reason, of course, the automatic watch does not require a battery. This technology also eliminates the need to wind up, because the watch itself uses kinetic energy to continuously update the accuracy. The spring, which is evenly tensioned at all times, guarantees an absolutely even running of the watch and thus an extremely precise time announcement. The bridge also called the slip clutch, is responsible for preventing the spring from over-tightening. Of course, the automatic watch also has a power reserve, which ensures that it does not stop even when it is idle. This power reserve for automatic watches varies between 12 and 36 hours depending on the model. If the watch is not worn for a longer period of time, it is advisable to purchase a watch winder. This small device simulates human arm movements to ensure that all watch functions remain active.
If you own one or more automatic watches, you have probably wondered whether you need a watch winder and if so, which one. The answer to these questions depends on the individual watch model and the comfort needs of the wearer. Find out here what complications a watch winder is absolutely recommended for and what you should pay attention to when purchasing.
What is a watch winder for?
Normally, automatic watches wind up automatically due to the arm movements of the person who wears them. Even if watches are at rest for a while, the date and time do not have to be reset as they usually have a power reserve.
However, if you own several automatic watches or only wear your watch sporadically, you probably know the following situation: After the watch has not been used for a long time, the movement stops, and the time and date are out of order. This does not happen with a watch winder, also known as a watch winder or watch winder. This turns the automatic watch attached to it slowly and steadily around its rotor axis. The movement mimics wearing on the wrist and allows the winding mechanism to work, which keeps the watch running.
