Following our recent presentation of the Classique Tourbillon 7357, we continue exploring the special horological creations unveiled by Breguet to mark the anniversary of Abraham-Louis Breguet’s most famous invention.
Today, the spotlight shifts from the classical refinement of the Classique line to the architectural layout of the Tradition collection with the debut of the Tradition Tourbillon 7047 (ref. 7047PT/YY/5ZU SL).
Issued in a highly exclusive 25-piece limited edition, this new platinum execution introduces a contemporary, monochromatic blue palette that highlights its complex mechanical architecture.
The Tradition Tourbillon 7047 is built around the combination of two historic engineering principles aimed at optimizing chronometric rate regularity: the Tourbillon regulator, patented by Abraham-Louis Breguet in 1801, and the fusee-and-chain transmission, a torque-regulating mechanism whose geometric principles were detailed by Leonardo da Vinci.
In a fusee-and-chain system, the chain unwinds from a mainspring barrel onto a cone-shaped element called the fusee. When the watch is fully wound and torque is at its maximum, the chain pulls on the smallest circumference at the top of the cone.
As the power diminishes, the chain moves down to the wider base. These opposing forces cancel each other out, ensuring a constant delivery of energy to the escapement regardless of the winding level.
Breguet has engineered this microscopic architecture to an extreme degree. The hand-assembled chain of the Calibre 569 is capable of withstanding a tensile force of 6 kilograms, ensuring exceptional structural integrity during operation.
This edition represents a stylistic departure for the 7047 family, opting for a high-contrast chromatic treatment. The mainplate, visible on both the dial side and through the sapphire caseback, features a glacier blue hue with a clean, sandblasted finish.
Contrasting against this cool backdrop are the bridges, the barrel, and the large fusee bridge, all finished in a deep Bleu de France. This proprietary shade was first introduced by the Maison in late 2025 on the Classique Répétition Minutes 7365 and is reserved for the manufacture’s most exclusive creations.
The chromatic consistency is carried out through the finer details of the movement. The one-minute Tourbillon cage, crafted from lightweight titanium, is treated in Bleu de France, as is the 77-link portion of the chain assembly.
To maintain visual harmony across the movement, the traditional ruby-red jewel on the Tourbillon bar has been replaced by a blue spinel, while the remaining functional jewels are retained to ensure the durability of the moving parts.
The off-centered time subdial at 7 o'clock is crafted from 18K palladium gold and decorated with a Grand Feu Bleu de France enamel. For the first time in this model's history, the chapter ring features Arabic numerals instead of Roman ones, paired with rhodium-plated 18K gold Breguet hands.
It is on this enamel surface that Breguet’s secret signature resides, hand-engraved using a historical pantograph. Completing the mechanics is a patented power reserve indicator positioned at 10 o’clock, which utilizes a reducer differential to display the remaining autonomy directly onto the barrel drum.
The 950 platinum case measures 41 mm in diameter, 16 mm in thickness, and 50.5 mm from lug to lug, featuring the traditional fluted caseband, welded lugs, and a water resistance of 3 bar (30 meters / 100 feet).
The sapphire crystal on the dial side features a double anti-reflective coating, while the caseback sapphire has a single coating.
The hand-wound manufacture Calibre 569 operates at a frequency of 2.5 Hz (18,000 vibrations per hour) with a power reserve of 55 hours.
It is equipped with an inverted in-line lever escapement featuring horns made of silicon, as too is the Breguet balance-spring. Thanks to its properties, this material makes the watch more resistant to the influence of magnetic fields while also improving precision.
The inscription "Brevet Du 7 Messidor An 9" refers to the date when the French Interior Minister granted Breguet the tourbillon patent based on the Republican calendar in force in France at the time and corresponding to June 26, 1801.
The watch is completed by a Bleu de France rubber strap with glacier blue topstitching, secured by a triple-blade folding clasp in 950 platinum.
The Breguet Tradition Tourbillon 7047 Platinum / Bleu de France is limited to 25 individually numbered pieces, hand-engraved from 1/25 to 25/25 on the caseback. The retail price is €292,900. breguet.com
