How does a quartz watch work?
For several centuries, mankind has not imagined a life without a watch and is constantly improving these mechanisms. It was possible to achieve incredible accuracy of the stroke - +/- 5 seconds per day. Such complicated devices are very expensive, but in everyday life it is enough for the accuracy provided by quartz watches, especially since they are accessible to absolutely everyone.
Today, the vast majority of world-produced watch movements are quartz. From time to time, looking at a moving arrow or flickering seconds on the scoreboard, you catch yourself thinking: "I wonder how they work?" And if you came across this article, let's stop for a second and find out, finally, what a quartz watch .
The main elements in the clock mechanism are a stepper motor and an electronic unit. Once a second, the unit sends an electric signal to the engine, and it turns the arrows. The engine and the unit are powered by a microbattery, which is designed for several years. It is not necessary to start a quartz watch.
The electronic unit consists of a generator of electric oscillations and a divider, their transforming. A quartz crystal is located in the generator, which is the source of periodic pulses. They are transmitted with great accuracy due to the piezoelectric effect of the crystal.
The peculiarity of the quartz generator is that the pulses generated by it have a very high frequency - 32768 oscillations per second. Therefore, the divider converts them into oscillations with a frequency of 1 hertz and transfers them to the winding of the stepper motor. When passing through the coil, the electric pulse excites a magnetic field in it, which causes the rotor to move for a half-turn. He, in turn, rotates the arrows. That's how the quartz watch works.
Their mechanism can be considered a mini-computer, because the programmed microcircuit can turn them into a multifunctional device that includes a stopwatch, chronograph, alarm clock, compass, etc. Sometimes a digital display is used instead of the dial. In this case, the time information is displayed in the form of numbers, but the basis is still a quartz oscillator.
The design of the mechanism on the crystals is very simple. It is noteworthy that the quartz watch does not contain elements working in a state of tension. That's why they are so durable. Their mechanism is constantly being improved. It's no wonder that quartz watches are becoming more and more popular.
We do not even think that the mechanisms based on the electronic quartz unit work in all known electronic devices that have the function of fixing time: computers, mobile phones, navigation systems, heart rate meters, etc.
We can say that choosing a quartz watch, we pay tribute to the present, because they were created only a little more than 40 years ago. Supporters of these watch movements are no less than mechanical ones. The watches we wear on our arm characterize us just like our favorite books, a car or a suit.
It is believed that quartz models are chosen by dynamic people, who in their watches are important for their accuracy and unpretentiousness. In addition to wrist watches, watches are made of quartz wall, table, fireplace. Almost every home and office has these tireless keepers of our time. Diverse in design and functions, original and simple, they are always close to us. They are needed and irreplaceable.
