What does quartz do in a watch?
The ability to convert voltage to and from mechanical stress is called piezoelectricity. Quartz crystals maintain a precise frequency standard, which helps to regulate the movement of a watch or clock, thus making the timepieces very accurate.
Is a quartz watch accurate?
At least one manufacturer of low-priced quartz watches specifies their accuracy as ±15 seconds per month, suggesting an accumulated error of just a few minutes per year. This type of accuracy is sufficient for most people, who are generally happy if their watch remains within a minute or two of the correct time.
Why is quartz expensive?
Unlike granite and marble, quartz doesn’t require sealing. This feature has made quartz highly popular among homeowners and like any other popular item, there is a high demand for the stone. The laws of demand and supply dictate that the higher the demand, the higher the price hence the high price of the stone.
How do I know if my watch is mechanical or quartz?
Aside from opening up the watch, an easy way to tell if a watch is quartz is to look at the seconds hand. A quartz watch will have the once-every-second ticking action while a mechanical piece will feature smoother sweeping strokes around the dial.
