Quartz Watch are battery powered and use minimal electricity that enables the battery to last for many years before replacing. They tend to be more accurate compared to mechanical watches because the oscillator of a quartz watch is steadier compared to the balance wheel of a mechanical watch.
The easiest way to differentiate a quartz watch from normal watches is to observe the second hand. The second hand on a quartz watch has a tick-tick movement that moves ones per second while the normal watch has a smooth, sweeping motion. Before purchasing a watch, it’s advisable to first figure out your needs.
