A mechanical watch is powered solely by a mainspring, without using electric power.
In a hand-wound mechanical watch, the movement's mainspring is wound by winding the crown. The mainspring of a self-winding mechanical watch is wound by the movement of the arm on which it is worn and stores energy.
While a quartz watch (powered by a battery) moves automatically, a mechanical watch does not move without human power. The "movement", made up of hundred of parts, can be called the "heart" of the mechanical watch.
The winding of the spring causes the "heart" to beat, and this human-like quality is one of the unique beauties of the mechanical watch, which continues to be loved around the world.
The movement of a mechanical watch is basically comprised of three main parts:
An analog quartz analog watch is the same as a mechanical watch in that it has gears to transmit power, but is powered by a battery and uses a quartz crystal as the oscillator to maintain precision.
The main difference in a digital watch is that it uses an electronic circuit in place of gears.
A mechanical watch is composed of precision parts carefully assembled by an experienced craftsman. The movement is the heart of the watch. What type of structure and motion does the movement employ to maintain the required accuracy?
Here is the basic structure and motion of a movement:
A hand-wound mechanical watch is powered by winding the crown to wind up the mainspring within the movement.
One of the beauties of a hand-wound watch is that it is necessary to perform the affectionate act of diligency winding the watch.
A self-winding mechanical watch is different from its hand-wound counterpart in that it is unnecessary to wind the crown. By moving the arm on wich the watch is worn, the rotor inside the movement rotates, thereby winding the mainspring.
Therefore, as long as the self-winding watch is worn on the arm, the watch will continue moving.
No batteries Used = Clean Energy
A mechanical watch is an economical and environmentally-friendly product that does not use electricity. A solar-powered watch has an internal battery for storing electricity, that does not need to be replaced.
Ecology = Returning to the Earth in the End
All of a mechanical watch's parts are made of natural materials. It is made entirely of metal and minerals (not including a rubber watch band). Therefore, it is a true ecological product that completely returns to the earth in he end.
Humanistic and Long Lasting.
A mechanical watch moves along with human movement. It stops when it is removed from the arm and not in use. Some see this a demerit, but is good for it to stop moving when not in use because the gears of a mechanical product wear out little by little over time. Because each part is replaceable, performing regular maintenance will allow it to be used almost perpetually and passed down from generation to generation.
Such characteristics as these are not often spoken about, but they are integral features of a mechanical watch.
Clean, ecological, and humanistic - doesn't a mechanical watch sound appealing to you?
