Types of movements
Mechanical movement
Mechanical watches use the force of an unwinding mainspring to move the intricately assembled gears and other components inside, thereby keeping time.
Mechanical watches are less accurate than quartz watches, and their assembly requires the skilled craftsmanship of technicians. As a result, they are popular, especially in the high-end price range, and exude a handcrafted feel and sense of luxury that quartz watches lack, making them recognized as a status symbol for luxury timepieces.
Hand Winding Formula
In the basic form of a mechanical movement, winding the crown of a wristwatch winds up the "mainspring," and the force of that unwinding spring moves the hands forward.
The "balance wheel," also known as the speed regulator, uses a component that vibrates like a pendulum to control time.
The higher the oscillation frequency, the more accurate the watch tends to be, and the evolution of mechanical watches hinges on how quickly this "balance wheel" can be rotated.
Automatic winding
The basic structure of the watch is the same as that of the Hand Winding, with a semicircular weight (rotor) built inside, which rotates and winds the mainspring.
Also known as "automatic," this type of watch gets its name from the fact that the weight rotates and winds the mainspring automatically when the wearer swings their arm.
Quartz Movement
Quartz The clock does not use mainspring power, but is powered by batteries.
By conducting electricity through a quartz crystal mounted inside, it creates vibrations in a precise rhythm and keeps the time.
It can maintain higher accuracy than mechanical watches.
By using electricity as a power source, it is possible to reduce size and weight in order to eliminate the need to combine many gears like mechanical watches, and low costs due to mass production.
Analogs Quartz
Analog Quartz is an analog display type of watch that is equipped with a motor-driven movement instead of a mainspring movement in mechanical watches.
Digital Quartz
Digital Quartz is a digital display type of watch that uses a liquid crystal display on the dial to display numbers.
Spring Drive
The spring drive is a mechanical movement developed by SEIKO that incorporates a speed regulation mechanism using a quartz crystal, and uses a mainspring as the power source to achieve the same high precision as a quartz watch.
The winding mainspring generates electricity at the same time as the hands are moved, and the speed regulation mechanism with a quartz crystal is operated, so unlike Quartz watches, batteries are not required.
