In the world of luxury watches, few things are more fascinating than the collision of tradition and innovation.

For more than two centuries, Breguet has been synonymous with the former. From its pioneering work in the tourbillon to its instantly recognizable guilloché dials and signature Breguet hands, the house has established some of the most enduring conventions in fine watchmaking. But beneath the traditional exterior of today’s watch lies a decidedly modern approach to chronometry.

A Breguet Classique Chronométrie, this Reference 7727BR/12/9WU combines the visual language of a traditional Breguet with one of the brand’s most technically ambitious modern movements. Housed in an 18K rose gold case measuring 41mm in diameter, it features a stepped bezel, signed crown, straight lugs, and sapphire crystal. Its silvered guilloché dial is complemented by black Roman numerals, a blued steel ‘Breguet’ handset, a power reserve indicator between 11 and 12 o’clock, a small seconds register at 12 o’clock, and a striking central seconds hand capable of displaying 1/10-second increments.

Powering the watch is Breguet’s manually wound Caliber 574DR, an extraordinary high-frequency movement beating at 10Hz — or 72,000 vibrations per hour. The movement incorporates a silicon escapement and balance spring alongside an innovative magnetic pivot system designed to improve the stability and precision of the balance. The result is a remarkably accurate mechanical wristwatch that can achieve a stated precision of -1/+3 seconds per day, while retaining a 60-hour power reserve.

Paired to a signed black alligator leather strap with an 18K rose gold deployant buckle, this example is accompanied by its inner box, pamphlets, and certificate of origin.

For the collector looking for a watch that marries the unmistakable elegance of traditional Breguet with genuinely forward-thinking mechanical engineering, look no further than this remarkable Classique Chronométrie Reference 7727BR/12/9WU.
