How A Quartz Watch Works?

Normal wind-up watches were in use long before the quartz watch came in to being. Wind-up watches were the best timekeeping instruments for people for a long time. Examining the workings of a wind-up watch is prudent before we look at the function of a quartz watch.

Wind-up watches are powered by a spring that was wound. Time in the watch is shown by the oscillator, also called a balance wheel. Two hands are employed to depict the time with a backdrop of numbers divided into 12 increments, called dial. All movements within the watch are linked with and governed by gears.

A wind-up watch is simple, but an excellent way of keeping time. There were some drawbacks of this watch. For instance, if you forgot to wind it up, you might not get an accurate time because the watch would run out of power. The accuracy was always doubtful. You were also not sure about the precision of this watch; all depended on matching and making of gears, spring and oscillator. The precision was also dependent on the timely winding of the watch; when the watch wound down, it would slow down and give inaccurate time.

In 1960s, there came some advancement in wind-up watches. The spring was replaced with battery, so you did not need to wind up the watch. The oscillator was replaced with a tuning fork that worked on frequency. However, the main issue of accuracy could not be addressed. Another development was the introduction of integrated circuits, but they were tended to be heavy because of their larger size. To overcome all these issues, quartz watches were introduced.

In quartz watches, a thin piece of synthetic quartz is used to measure time. Since synthetic quartz is consistent, it is preferred over natural quartz. Vibrations are created in the quartz clock, when an electric charge is applied. Precise time is measured by measuring these vibrations. Quartz is widely used in modern watches today.

Most quartz watches are powered with battery. Nevertheless, there are some that are powered by tiny kinetic generator that works by the movement of wrist. The tiny rotors in the watch spin with this movement and create electricity that powers the watch. A quartz watch also has an oscillator like a wind-up watch, but in its case, quartz serves as an oscillator that moves steadily. The oscillator indicates the time on your watch.

Quartz is a perfect material because it loses very less energy when it vibrates. The vibrations stay stable and demonstrate piezoelectric effect. The vibration is generated by this effect.

Loosing less than one minute per year is what makes quartz watches more accurate than wind-up watches. In the long term, accuracy of a mechanical watch is always in question, because it depends on different factors like making and quality. The other major difference is that, unlike wind-up watches, quartz watches do not require winding for operation. Just replace the batteries, and a quartz watch will last forever. Your choice should be clear; quartz watch for precise time.
