A quartz alarm clock can also be called a "crystal vibration electronic watch" because it utilizes the "oscillation phenomenon" of crystal chips. When the crystal receives external applied voltage, it will have deformation and stretching properties. On the contrary, if the crystal is compressed, it will generate electricity at both ends of the crystal; This property can also be seen on many crystals, known as the "piezoelectric effect". A quartz watch is a crystal that uses periodic and continuous vibrations to provide us with accurate time.

Firstly, by applying electricity to the crystal chip inside the quartz watch, the crystal will vibrate correctly at a frequency of 32768 Hz; Then, this frequency must be converted into a signal current cycle of 1Hz (a change in current between one second). Increase the amplitude of the signal further (due to the weak current generated by vibration), and then activate the rotor gear with the signal current. The second hand on the watch will start accordingly, and the movement of the minute hand and hour hand is related to the principle of mechanical structure. For example, if the second hand jumps 60 times, the minute hand will jump. All quartz watches are equipped with a battery. It provides energy for an integrated circuit and a quartz resonator, vibrating 317621 times per second. There is something faster than this. Integrated circuits are the "brain" of the table. It controls the vibration of the quartz resonator and acts as a frequency divider. 32712 vibrations were split in half 15 times to generate one pulse per second. With the "raw materials" that last for a second, you can drive the display. What is the analog needle display? In order to convert integrated circuit pulses into motion, the analog pointer quartz meter is equipped with a speed increasing motor, including an electromagnetic rotor, which rotates 180 degrees, or one second, for each pulse it receives.

The rotor is connected to a dragging system composed of three gears, driving three pointers (hour hand, minute hand, and second hand) to display the time on the dial. A display screen can also be added to display the week, date, and elapsed time. Solid state quartz watch In a solid state quartz watch, pulses in units of one second are transmitted to the second hand part of the integrated circuit, which is responsible for organizing the liquid crystal lines of the liquid crystal display mode to form a number. This type is common in table objects. In the watchmaking industry, this is usually used to produce extremely cheap products on a large scale. Asian manufacturers have already monopolized this field. In more sophisticated watch styles, the "solid state" has a large number of functions, such as phone numbers, appointment registration books, etc., depending on the size of the memory installed inside. A mixed quartz watch is a type of quartz watch that has two display functions, namely analog pointer type and digital type. The latter provides auxiliary information such as week and date, precise timing function, and time zone. This watch is equipped with an integrated circuit and a micro engine.
