Summary of Breguet Classique 7225 with Magnetic Pivot
This text details the innovative Breguet Classique 7225, created to celebrate the brand’s 250th anniversary. The key feature is its magnetic pivot, a groundbreaking technology designed to overcome limitations of high-frequency movements.
Here’s a breakdown of the key points:
* Problem Solved: Traditional high-frequency movements suffer from increased wear and instability. The magnetic pivot aims to enable higher frequencies without these drawbacks.
* How it Works: Two micro-magnets create a magnetic field around the balance staff, levitating it and reducing friction. A intentional imbalance in the field ensures constant contact with the endstones, and automatically re-centers the shaft after impacts.
* Benefits:
* Stability: Enhanced stability, especially after shocks.
* Reduced Friction: Minimizes friction due to the small contact area.
* High Frequency: Enables a 10Hz (72,000 vph) frequency.
* Precision: Achieves a remarkable accuracy of +/- 1 second per day.
* Materials: The use of silicon for the balance spring, pallet-lever, and escape wheel is crucial, as silicon is anti-magnetic and allows for this technology to function.
* Unique Feature: A hidden “easter egg” – a phenakistoscope-type animation on the escape wheel displays “1775” and “2025” in a morphing effect, celebrating the anniversary.
In essence, the breguet Classique 7225 represents a critically important advancement in mechanical watchmaking, leveraging magnetism to achieve a new level of performance and stability.
