What is an automatic watch? What are its specifics?
What is a movement ?
Movementis the mechanism that allows a watch to work. AtCharlie Paris, we supply from Citizen, a Japanese manufacturer formost of our automatic watches.The major Swiss watch brands usually own their own manufacture, which is why their prices are very high.
For our watches, we use two large families ofmovement :
Quartz movementswhich are simple mechanisms and work with a stack. These movements have the advantage of being the most accurate. We use Quartz movements for watches from our women's collection (Aurore, Sully, Monceau) and for our men's watches (Bastille, Horizon, Concordia and GR)
- Automatic mechanical movements, use wheels and springs to operate through kinetic energy. That is, the energy that a body possesses as a result of its movement. The movement of a automatic watch is more complex to manufacture and design. It is the darling of watch lovers and collectors. They prove a real know-how.Our automatic watch Initial includes an automatic movement.
The components of an automatic watch :
To fully understand the operation of a watch that has an automatic movement, you must first learn more about its main components !
Here are its main components:
Rotor : this is the oscillating weight of the mechanism. In plain it is a weight in the form of a semicircle attached to the movement. It rotates 360° according to the movements of the wrist and allows thanks to a series of mechanisms, to wind up the barrel spring thus providing mechanical energy to the watch.
Crown : This is the small wheel located on the right side of your watch. It is fixed on the winding shaft and is used to reassemble the motor spring.
The barrel spring : It is an elastic steel band that provides the energy necessary for movement when it is armed, that is, tense.
The transmission system (cog) : It transmits the energy accumulated in the barrel spring to the exhaust wheel via a series of small wheels.
Exhaust wheel : it has the function of letting out the energy conveyed by the cogs to the anchor, intermittently and regularly. This is the watch maintenance member.
Pendulum : This is the heart of the movement. It beats between 5 and 10 times per second in a circular manner. It is he who is at the origin of the " tic-tac ", noise produced by the pallets on the teeth of the exhaust wheel, due to its back and forth movement. It is the regulating organ of movement.
Ruby : These are stones of high hardness that allow to reduce friction and wear of the components of the mechanism.

Now that you know the main components of the mechanical movement perfectly, how does it actually work ?
Here are the six main steps that help you better understand how your watch hands rotate:
- Wrist movements rotate the rotor and so go up the barrel spring. The winding can also be done by turning the crown ;
- The transmission system transfer energy to the exhaust wheel ;
- Exhaust doses energy in regular sections ;
- The pendulum uses this regular energy to beat back and forth consistently ;
- At each beating series, a series of wheel transfer energy to the needle show ;
- The hands move forward on the dial.
Our initial automatic watch includes a balance that recharges the barrel spring by wrist movements. Thus, if the watch is worn regularly, it will not need to be wound manually.
An automatic watch has a nice aesthetic advantage. Indeed, the second hand does not make a leap of a second but much more small jumps. The whole thing is more linear.
