Power Reserve
The power reserve in watches is a feature that many people are not aware of, but is still necessary. Power reserve is ultimately a watch's ability to keep time despite not being wound. It is considered by many to be a type of security system within a watch and is therefore more than just a nice extra for watch lovers.
There are many different types of power reserves, but ultimately they all have the same purpose. It ensures that a watch can continue to show the time when the energy source (usually a spring in the mechanical watch movement) no longer has enough tension to keep the watch running.
The simplest type of power reserve is the spring, which is wound manually. This type of power reserve has been around for centuries and is still found in many mechanical watches. In principle, the spring is wound simply by turning the crown on the side of the watch. When the spring is wound, it releases the necessary energy to the movement to keep the watch running. However, if the spring discharges slowly, the time will display more slowly and the watch will eventually stop.
Today there are also many modern types of power reserves. Some automatic watches are equipped with a power reserve that responds to wrist movements. Every time the wearer moves their arm, a small weight moves within the watch, releasing energy into the movement. This type of power reserve is particularly convenient for people who wear their watch frequently and don't have to remember to wind it manually.
Another type of modern power reserve is the quartz watch with battery. These watches are equipped with a small battery that powers the watch. If the battery is empty, the watch will no longer function properly. However, most quartz watches have a warning function that tells the wearer that the battery is about to run out.
In summary, a power reserve is a crucial feature in every watch. It ensures that the clock continues to run even when the energy source is empty. There are many different types of power reserves, but ultimately they all have the same purpose. A watch without a power reserve would simply be useless, but thanks to modern technologies and innovations, it is becoming increasingly intelligent and practical. When you buy a watch, it is therefore important to think about the power reserve.
