Breguet Continues its Perfect Harmony of Science and Innovation with Classique Chronométrie 7727

Breguet continues with its perfect harmony of science and innovation with timepiece Classique Chronométrie 7727. Breguet famous founder, Abraham-Louis Breguet continues to be the driving force in the development and innovative designs of its exquisite timepieces. Using the fundamentals of research and development, instrumental to its watch making designs, Breguet for its second year revealed and unveiled its innovative talents with Classique Chronométrie 7727 at BaselWorld 2012.

Classique Chronométrie 7727 is a tribute to Abraham-Louis Breguet’s indomitable pioneering spirit of innovation. His portfolio of inventions, to name a few, includes the Souscription watch design and the complex mechanism design for the tourbillon. Viewing the Breguet Classique Chronométrie 7727 it is understandable why Breguet thrives to promote their founders legacy in each of its watch designs. President and CEO Marc A. Hayek supports and cultivates investments in research and development of new technologies and materials, which Breguet successfully filed for over 100 patents in the past 10 years for its for chronometry and acoustic regulators.


Classique Chronométrie 7727 represents Breguet continued quest to accurately measure time. The watch is set in rose gold and exhibits Breguet’s latest innovation. The watch oscillates at a frequency of 10 Hz, a first time milestone for a non-chronograph watch considering the frequency was purposed for precision and stability of a conventional mechanical watch. Increasing the frequency and power of the mechanical oscillation improves the timekeeping performance of the balance and spring.

Classique Chronométrie 7727 regulating power is approximately 800 microwatts; most watches have less than 200 microwatts for chronometer performance. Breguet’s silicon mastery enables this high frequency to be achieved with a conventional balance-spring. Since silicon components are easily manufactured for high precision, they are also exceptionally lightweight and non-magnetic. Therefore the watch is equipped with balance-spring, pallet lever and escape-wheel in silicon; and the mainspring barrel of the watch keeps the watch operational for 60 hours.


Classique Chronométrie 7727 aesthetic features include a 41 mm diameter 18-carat gold case with fine ridges on the caseband, a sapphire-crystal case-back with welded lugs. The dial is 18-carat silvered gold, the engine-turned by hand in six different patterns. Individually signed Breguet and numbered. It has an off centered chapter ring with noble Roman numerals. The power-reserve indicator is at 5 o’clock, small seconds at 12 o’clock, and the silicon indicator tenths-of a-second hand is at 1o’clock with “open-moon” Breguet hands in polished steel.


The movement of this watch is hand-wound numbered and signed Breguet Calibre 574 DR, 14 lignes, 45 jewels, with a leather wrist strap.


Classique Chronométrie 7727 is an iconic testament of Breguet’s commitment to harmonize science and innovation in the development and designs of its timepieces. Abraham-Louis Breguet spirit of perfection lives on in Breguet timepieces.
