While quartz movements are known for their remarkable accuracy, not all quartz movements are created equal. The accuracy of a quartz movement can vary based on factors such as the quality of components, manufacturing processes, and calibration. High-quality quartz movements are equipped with precision-cut quartz crystals that resonate at a consistent frequency, resulting in reliable timekeeping. Cheaper or lower-quality quartz movements might exhibit slight variations in accuracy, but overall, quartz movements are known for their impressive precision compared to mechanical counterparts.
