What’s a Normal Daily Deviation for Mechanical Watches?
Understanding Timekeeping Accuracy: Mechanical watches, unlike their quartz counterparts, rely on a complex system of gears and springs to keep time. While quartz watches may boast monthly deviations as little as 15 seconds, high-precision quartz movements can narrow it down to just a few seconds a year.
Mechanical Watches’ Daily Deviation: Due to influences like gravity and temperature changes, mechanical watches measure their accuracy daily. Standard deviations within 30 seconds per day are considered normal. However, superior calibers, such as those certified by observatories, may limit deviations to around 10 seconds daily.
Common Causes for Increased Deviation:
– Battery Power: A slowdown in quartz watches often signifies a need for battery replacement.
– Insufficient Power Reserve: For automatic watches, insufficient movement may lead to power deficits, remediable by manual winding.
– Magnetization: When a watch’s hairspring becomes magnetized, accuracy declines.
– Maintenance Needs: A lack of lubrication or worn internal components can affect performance, necessitating professional servicing.
– Impact Damage: Precision can be compromised by shocks or drops.
Mitigating Factors: Besides these common issues, environmental temperatures and wearing habits may also introduce deviations. However, there’s no cause for alarm. Professional inspections and adjustments at authorized service centers can restore your watch to its optimal timekeeping accuracy.
