Factors Affecting Mechanical Watch Timekeeping Accuracy

Factors Affecting Mechanical Watch Timekeeping Accuracy – Insights from AIERS Watch

Watches are among humanity’s most precise inventions. While quartz watches are more accurate than mechanical watches, several factors can influence the timekeeping accuracy of mechanical watches. Eltime Watch Manufacturer shares insights on this topic.

According to watch manufacturers, the following factors can impact mechanical watch timekeeping:

1. Temperature Influence
Temperature changes affect the working length of the balance spring and alter the inertia of the balance wheel, directly impacting timekeeping accuracy. Additionally, temperature fluctuations influence the viscosity of lubricants, affecting transmission efficiency and thus timekeeping.

2. Adjusting Screw (快慢针)
The adjusting screw serves as a convenient timing adjustment mechanism. However, both theoretical and practical evidence show that it can disrupt the system’s isochronism and cause positional deviations. These timing errors are random and cannot be effectively compensated or canceled out.

3. Balance Spring Equilibrium
In conventional balance frames, the center of gravity of the balance spring shifts with changes in the balance wheel’s swing angle. Under gravitational effects, this creates positional errors.

4. External Influences
External factors stem from the watch’s operating environment. These include impacts from shocks, water exposure, magnetic fields, and other environmental conditions.

These factors directly affect the timekeeping accuracy of mechanical watches. For solutions to these issues, please stay tuned for our next sharing session. You can also consult Eltime Watch Manufacturer anytime.
