Hello everyone, I’m the editor at the C Factory official watch website. Today, let’s dive into the fascinating world of mechanical watches, specifically focusing on the precision of mechanical watches which largely depends on the stability of the oscillation period of the balance wheel and hairspring. This assembly acts as the time base for the watch, but its stability can be influenced by various factors:

1. Amplitude Impact: The swing range of the balance wheel affects timing accuracy.
2. Position Changes: The orientation of the watch can cause variations in timekeeping.
3. Hairspring Regulation: Adjustments to the regulator can speed up or slow down the watch.
4. Temperature Variations: Changes in temperature can affect the metal components in the movement, altering their dimensions and thus, the timing.
5. Magnetic Fields: Exposure to magnetic fields can affect the metal components of the movement.
6. Shock and Vibrations: Physical shocks can alter the regulation of the movement or damage it.
7. Manufacturing Tolerances of Watch Movement Parts: Imperfections in the manufacture of movement components can affect performance.
8. Other Factors: Such as humidity, air pressure changes, and the entry of minute particles inside the watch due to imperfect case sealing, which can also affect the accuracy.

The stability of a watch under these conditions is a testament to its quality, and here’s how these aspects are tested and adjusted:

Testing Watch Accuracy:

1. Daily Rate Error: Indicates the quality of the watch’s accuracy over 24 hours, comparing corrections from one day to the next.
2. Daily Rate Variation: Differences between the errors of two consecutive days.
3. Average Daily Rate Error: Comparison between single day errors and their average over several days.
4. Isochronism Error: The difference in timekeeping when fully wound versus after 24 hours.
5. Positional Error: Variations in timing when the watch is placed in different orientations.
6. Temperature Error: Adjustments in the timekeeping based on changes in temperature.

These tests ensure that a watch maintains its precision under various conditions, which are crucial for maintaining consistent performance.

Adjusting Watch Accuracy:

Adjustments are typically made by manipulating the hairspring to change its effective length. However, achieving precise adjustments within seconds can be challenging without specialized tools or devices due to the sensitivity of the components. Many high-end watches include a micro-adjustment mechanism that allows for finer control over the timing adjustments.

Maintaining Watch Accuracy:

Maintaining accuracy in a mechanical watch isn’t about making a single correction; rather, it involves continuous monitoring and adjustment due to the inherently dynamic nature of mechanical movements. Factors such as the wearer’s activity level, storage position at night, and the natural wear and tear on the watch’s internal components all play a role in its ongoing accuracy.

For optimal performance, it’s advisable to fully wind automatic watches regularly and keep them in positions that mitigate any consistent timing errors identified through testing.

In conclusion, the intricate dance of mechanics inside a watch is both an art and a science, requiring careful attention to detail and regular maintenance to ensure optimal performance.
