What is an automatic watch ?

Qu'est ce qu'une montre automatique ?

The automatic watch is very popular with watch enthusiasts, especially for the complexity of their movement. But what is an automatic watch? What are its specificities? In. this article, we will explain in detail what an automatic watch is.

  1. What is that one movement? 
  2. The components of an automatic watch

  3. The operation of an automatic movement watch


1. What is it one movement? 

Movement is the mechanism that allows a watch to work. At Charlie Paris, we source most of our automatic watches from Citizen, a Japanese manufacturer. The major Swiss watch brands generally have their own manufacture, which is why their prices are very high.

For our watches, we use two main families of movements:

  • Quartz movementswhich are simple mechanisms and work with a battery. These movements have the advantage of being the most precise. We use Quartz movements for our ladies' collection watches (Aurore, Sully, Monceau) and for our men's watches (Bastille, Horizon, Concordia and GR)
  • Automatic mechanical movements, use wheels and springs to operate using kinetic energy. That is, the energy that a body possesses as a result of its movement. The movement of an automatic watch is more complex to manufacture and design. It is the darling of watch enthusiasts and collectors. They prove real know-how. Our Initial automatic watch features an automatic movement.


2. The components of an automatic watch:

To fully understand how a watch that has an automatic movement works, you must first learn more about its main components!

Here are its main components:

  • The rotor: it is the oscillating weight of the mechanism. Clearly it is a semi-circle shaped weight attached to the movement. It rotates 360 ° according to the movements of the wrist and allows, thanks to a series of mechanisms, to wind the barrel spring, thus providing mechanical energy to the watch.
  • The crown : This is the small wheel located on the right side of your watch. It is attached to the winding shaft and is used to wind the mainspring.
  • The spring of Barrel: It is an elastic band of steel that provides the energy necessary for movement when it is armed, that is, stretched.
  • The transmission system (cog): It transmits the energy stored in the barrel spring to the escapement wheel via a series of small wheels.
  • Exhaust wheel: its function is to release the energy conveyed by the cogs to the anchor, intermittently and regularly. This is the watch's maintenance organ.
  • The balance: This is the heart of the movement. It beats between 5 and 10 times per second in a circular fashion. It is he who is responsible for the "ticking" noise produced by the paddles on the teeth of the escapement wheel due to its back and forth movement. It is the regulating organ of movement.
  • Rubies: They are very hard stones that reduce friction and wear on the components of the mechanism.


3. The operation of an automatic movement watch

Now that you are fully familiar with the main components of mechanical movement, how does it actually work?

Here are the six main steps to better understand how the hands of your watch turn:

  1. Wrist movements rotate the rotor and thus go up the barrel spring. Reassembly can also be done by turning the crowned ;
  2. The transmission system transfers energy to escape wheel ;
  3. The exhaust doses the energy in regular sections;
  4. The pendulum uses this steady energy to beat back and forth steadily;
  5. With each series of beats, a series of wheels transfer energy to the needles of the watch;
  6. The hands advance on the dial.

Our Initial automatic watch features a balance wheel that recharges the barrel spring through wrist movements. Thus, if the watch is worn regularly, it will not need to be manually wound.

An automatic watch has a nice aesthetic advantage. This is because the seconds hand does not jump a second but many more small jumps. Everything is more linear.
