Breguet Classique 7225: Magnetic Pivot Watch Review
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.
