New 7727 Classique Chronométrie 10Hz Luxury Watch by Breguet
Breguet has long been a leading luxury watchmaker. Abraham-Louis Breguet initially desired to constantly improve the accuracy and reliability of his watches through numerous inventions, ranging from the perpétuelle selfwinding watch to the tourbillon.
The Classique Chronométrie 7727, packed with new discoveries and technological inventions, is a prime example as the achievement of several years of research into high frequency, magnetism and new materials.
With the patent of November 7, 2010 protecting the magnetic pivot, Breguet has set a new milestone in watchmaking history. The magnetic field crossing through the balancestaff keeps the balance stable.
These silicon parts allow the frequency of the Classique Chronométrie to be increased to 10 Hz, enabling the measurement of a 20th of a second. The Classique Chronométrie is also equipped with twin 180° symmetrically deploying balance springs, thereby balancing out their respective forces exercised on the balance-staff as well as contributing to the stability.
