Do automatic mechanical watches and quartz watches have significant errors?

Both automatic mechanical watches and quartz watches are very common in life. They both exist to provide accurate timing. The accuracy of quartz watches is higher than that of automatic mechanical watches, but there will still be certain errors between the two watches.

 1. Automatic mechanical watch

Automatic mechanical watches rely on mechanical movement and do not require batteries. They use a complex system of gears, springs, and an oscillating weight (rotor) that winds the mainspring that powers the watch. While mechanical watches can be very accurate, they are not as accurate as quartz watches.

 The accuracy of a mechanical watch is affected by several factors:

(1) Quality and workmanship: High-end mechanical watches are usually more accurate due to their superior workmanship and precise construction.

(2) Adjustment: Mechanical watches may require regular adjustments and adjustments to ensure accuracy. Slight changes may occur over time due to factors such as temperature, gravity, and wear. Watchmakers can adjust movements to minimize these errors.

(3) Power reserve: The power reserve affects the accuracy of a mechanical watch. As the mainspring loosens, the accuracy of the watch may decrease.

In general, modern mechanical watches can provide reasonable accuracy in the range of seconds per day, but this can vary slightly depending on various factors.

 2. Quartz watch

Quartz watches use a battery-powered quartz crystal oscillator to regulate timekeeping. These watches are known for their high precision and reliability. When an electric current is applied, the quartz crystal vibrates precisely, providing the watch with a consistent and accurate time reference.

 Quartz watches are generally more accurate than mechanical watches due to the precise oscillations of the quartz crystal. They can provide accuracy in the range of seconds per month or even per year, depending on the quality of the movement and the calibration of the watch.

 To sum up, while automatic mechanical watches are generally not as accurate as quartz watches, they can still provide reliable timekeeping within a reasonable few seconds per day. Quartz watches, on the other hand, are known for their high precision due to the use of a quartz crystal oscillator. However, there may be differences in the accuracy of different brands, models, and individual watches. It is recommended to communicate with the watch factory more.
