The Breguet Classique Chronométrie Ref. 7727BR/12/9WU is one of the most technically advanced wristwatches ever created by Breguet, combining traditional haute horology with groundbreaking modern innovation.

Housed in a polished 18k rose gold 41mm case with the iconic Breguet coined edge, this exceptional timepiece is powered by the revolutionary Breguet Calibre 574DR, beating at an extraordinary 10 Hz (72,000 vibrations per hour). Extensive use of silicon components and a patented magnetic pivot balance system allows the balance staff to automatically re-center after shocks, ensuring remarkable stability and precision rated at –1 / +3 seconds per day.

The silver guilloché dial is a masterpiece in itself, featuring multiple hand-engine-turned patterns, a 1/10th-of-a-second indicator, small seconds, and a power reserve display. A rare fusion of classical beauty and cutting-edge chronometry.
