Accuracy in horology

In horology, accuracy refers to how closely a watch's timekeeping aligns with the actual time over a given period. It indicates the precision of the movement in maintaining correct time, typically measured in seconds gained or lost per day. High-accuracy watches exhibit minimal deviation, ensuring reliable timekeeping, while less accurate ones may drift more. Factors influencing accuracy include the quality of materials, craftsmanship, and movement design. Overall, accuracy is a key indicator of a watch’s reliability and performance in reproducing precise time.
