316L Steel - Black Leather - Chronograph - Quartz - 44mm

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.
