Collection: sm600m quartz

The kinetic energy of a quartz watch comes from a battery, and the difference between it and a automatic watch is that a quartz watch can keep working without winding up or oscillating the balance wheel. Therefore, a quartz watch is more suitable for sedentary or elderly people, and its timing function is more accurate than an automatic watch. However, the lifespan of a quartz watch is much shorter than that of an automatic watch. It usually needs to replace the battery after 3 years of operation, while an automatic watch can work for more than 10 years if well-maintained.The back of a quartz watch is sealed, whereas that of an automatic watch is transparent, allowing clear visibility of the movement. Additionally, the second hand of an automatic watch moves more smoothly than that of a quartz watch.
