Quartz Watch functionality

A quartz watch, often known as a clock, is a wristwatch that employs a quartz crystal, a battery, and an electronic oscillator as its main components. Quartz watches are those that have quartz as part of their mechanism. It is a whole different method than mechanical or automatic watches. It is regarded as one of the most precise. Quartz wristwatches exist in different sizes and patterns, and quartz clocks can be free-standing or mounted on the wall. A low-frequency, small piece of quartz crystal (silicon dioxide) is present in the watch, which is either formed like a tuning fork or positioned like an integrated circuit and chemically etched into shape. 

Jacques and Pierre Curie discovered quartz’s remarkable characteristics in 1880. The fact that it is piezoelectric is an essential feature. Quartz creates an electric charge on its surface when squeezed or twisted. It also works in the opposite direction: if you apply a modest electrical phenomenon to quartz, it will compress or bend somewhat. 

Furthermore, quartz has exceptional thermal resistance. Consider a bell that rings as a result of vibrations. 

Electrical Circuits And Quartz:

Warren Morrison found in 1928 that he could sustain a constant beat by passing a charge through a quartz crystal. It was crucial for the watch industry’s development during the next few decades. 

It discovered that by utilizing electrodes and an electric circuit, the electrical charge is formed naturally on the surface of quartz crystal under pressure could be removed from the material.

Batteries:

As a result, every quartz watch necessitates the use of a battery. Through the circuit, the battery delivers electricity to the quartz. Due to its piezoelectric capabilities, the device causes the quartz to vibrate (oscillate) at a highly particular frequency: 32768 times per second. The circuit counts how many vibrations there are and utilizes that information to generate an electric pulse. Every 32768 vibrations, there is one pulse. 

To make things simple, I’ll explain how a quartz watch works in a few bullets:

  • The electronics get current from the battery (microchips).
  • The quartz crystal will vibrate 32,728 times per second due to the circuitry.
  • The electronics detect and count the oscillations, and after it has measured 32,768 vibrations, it will unleash an electrical pulse.
  • It is excreting at 1-second intervals due to the 32,728 variations per second. The stepping motor, which is a bronze copper coil, is driven by an electric pulse.
  • It receives a pulse once per second, converting electrical energy to mechanical energy.
  • The stepping motor’s mechanical power spins the gears, which causes the dial’s hands to tick.

How Does a Quartz Watch’s Stepping Motor Work? 

The quartz watch’s muscles are the stepping motors. After the microchip has interpreted the vibrations caused by the quartz crystal, the stepping machine gets the signal from the microchip. A magnetic axle within the stepping motor responds to the sign supplied by the stepping generator. The stepping generator sends a shifting pattern of magnetic pulses. The magnetic field changes the pole once per second, causing the axle and, as a result, the gear in the stepping motor to revolve.
