The most important thing about an automatic watch
Automatic watches, also known as automatic mechanical watches, are a fascinating piece of engineering that combines precision, elegance and tradition. Unlike battery-powered quartz watches, automatic watches do not require an external power source (battery) to operate.
1. The heart of the watch: The Caliber
The fundamental element of an automatic watch is its caliber, a complex mechanism made up of hundreds of tiny parts that work together in a synchronized manner. The heart of the caliber is the escapement, which regulates the release of energy from the mainspring to drive the watch's hands.
2. The power of automatic movement
The magic of automatic watches lies in converting movement into energy. A heavy rotor, or oscillating mass, rotates inside the watch thanks to the movement of the wearer's arm, transmitting this movement to the winding mechanism, which tensions the mainspring. The energy stored in the spring is gradually released, allowing the watch to run.
3. Accuracy and reliability
High-quality automatic watches are known for their precision and reliability. With proper care, an automatic watch can run for decades without requiring extensive maintenance.
4. A miniature work of art
Beyond their functionality, automatic watches are considered miniature works of art. The complexity of their mechanism, the quality of their materials and the beauty of their design make them coveted pieces by collectors and watch lovers.
5. A legacy of tradition
Automatic watches have a rich history dating back centuries. Its evolution has been marked by innovation and the constant search for perfection.
