The tourbillon consists of a rotating cage that houses the escapement and balance wheel. This cage completes a full rotation usually once per minute, averaging out the positional errors that may occur when the watch is in different orientations. By constantly changing the position of the escapement relative to gravity, the tourbillon helps improve timekeeping precision.

Watch enthusiasts often admire tourbillons not only for their technical prowess but also for their aesthetic appeal. The intricate spinning cage visible through the dial adds a touch of sophistication and complexity to the timepiece. However, it's essential to note that while tourbillons are impressive feats of engineering, their practical impact on daily timekeeping accuracy in modern watches is a topic of debate among horologists.

Impacts of Magnetism on Movements

Magnetism can significantly impact the accuracy and functionality of watch movements. When a watch movement is exposed to magnetic fields, it can cause the components within the movement to become magnetized. This magnetization can lead to erratic timekeeping, as the balance wheel and escapement, crucial for regulating the watch's accuracy, may no longer oscillate properly.

The effects of magnetism on a watch movement can be subtle, making it challenging to detect the issue at first. However, if you notice that your watch is consistently running fast or slow, even after being regulated, magnetism could be the culprit.

To combat the impacts of magnetism on watch movements, watchmakers often utilize anti-magnetic materials such as silicon for certain components. Additionally, some watches are equipped with inner cases made of soft iron that help to deflect magnetic fields away from the movement.

If you suspect that your watch has been affected by magnetism, it's advisable to have it demagnetized by a professional watchmaker.
