In 1969, the first quartz watch was published. After so many years development, more and more people would show their interests to the quartz watch.
The timing accuracy of a quartz watch is about 100 times higher than a mechanical watch, and the error of a quartz watch is within 0.5 seconds per day.
Quartz watches do not need winding and maintaining, which is convenience for the daily use. And the one thing you need to do is that replace the batter every two years.
There is a lot of possibility in the appearance design in a quartz watch. The structure of a quartz watch is more simple than a mechanical watch, and even the plastic can be used for the movement and gears, so the thin, light is the appearance of a quartz watch. In addition, the time spent in quartz watches research and develop is less and the cost is low.
There are mainly two parts to support a quartz watch working.
1. The battery supply the energy for the quartz movement.
2. The quartz crystal oscillator - the inner core of a quartz watch.
In simple terms, the principle is Piezoelectricity that mechanical energy and electrical energy have the inter-conversion in dielectric materials
