What is the difference between quartz watches and mechanical watches?

What is the difference between quartz watches and mechanical watches?

As a watch entry knowledge, the difference between quartz watch and mechanical watch must know.
Press the power source can watch divided into mechanical watches and electronic watches two categories:
Mechanical watch:
A common mechanical watch movement of 90 to 100 components, more features of the movement of 1400 components, the power of the mechanical watch is a curly leaf spring, stored in the spring energy to promote the work table To achieve the purpose of timing. Mechanical watches can be divided into manual mechanical watches and automatic mechanical watches two:
(1) manual mechanical watch: hand winding movement, rotating the crown, the movement within the spring will release the energy to promote watch operation.
(2) Automatic mechanical watch: The power of the self-winding movement is driven by the weight of the flying turtle in the movement. When the arm wearing the watch swings, it will drive the flying lead to rotate, meanwhile, drive the clockwork to wind up the watch.
Mechanical watch features:
(1) mechanical watch travel time and quartz watch is different, mechanical watch second hand is a continuous uninterrupted walk.
(2) Due to the complexity of the movement of the mechanical watch, travel error is large (depending on the brand), the Observatory movement error is small, one day's error is normal within -4 / + 6 seconds. Mechanical error when walking time can not be accumulated, the watch over time to be debugged
(3) Fine technology, easy to use, on the foot of the clock can go 36 hours or more.
(4) long life movement.
(5) look thicker than the quartz watch some (depending on the brand may be), some brands are also very thin, but are generally manual mechanical watches.

What is the difference between quartz watches and mechanical watches?
digital watch
Can be divided into digital quartz electronic watches, quartz watch pointer and automatic quartz watch and photodynamic energy watch
1. Digital quartz watch: the piezoelectric effect of quartz crystal and diode liquid
Crystal display combines the watch, its function is completely completed by the electronic components.
2 pointer quartz watch: quartz watch energy from silver oxide button batteries, silver oxide button batteries to the integrated circuit to provide a specific voltage, through which the oscillation circuit and the quartz resonator oscillator quartz oscillator to form the oscillation circuit source . From the oscillation circuit output frequency of 32768 Hz into the frequency divider circuit after the division of the signal after 16 to produce a 0.5Hz pulse signal, and then narrow pulse output pulse signal into the drive circuit to enlarge, and the formation of alternating changes Of the two-way pulse signal, which drives the stepper motor for intermittent rotation, and further drive the transmission wheel train, so that the hands accurately show the time.
Battery ----- provide energy, to ensure the normal operation of the circuit.
The circuit part ----- provide the electric pulse with stable frequency and power, and push the stepping motor to rotate.
X stepper motor ----- convert the electrical energy output from the electronics into mechanical energy.
Transmission wheel ----- the motor output mechanical energy rotation transferred to the second wheel, wheel, wheel, dial calendar wheel.
Walking mechanism ----- driven pointer rotation instructions time.
Dial mechanism ----- adjust the time and calendar, calendar, but also has seconds function.
