In celebration of its 250th anniversary, Breguet has launched one of its most poetic and technically daring creations to date—the Classique Tourbillon Sidéral 7255. Released on 26 June 2025, exactly 224 years after Abraham-Louis Breguet received the patent for his revolutionary tourbillon invention, this new timepiece embodies both a homage to history and a masterstroke of modern watchmaking. Only 50 pieces of this limited edition will be crafted, ensuring its rarity and prestige.
At its heart lies a flying tourbillon with a mysterious construction, marking a first in Breguet’s long legacy. Elevated prominently within the case, the tourbillon appears to levitate above the aventurine enamel dial, thanks to sapphire components and hidden mechanics that eliminate visible links to the rest of the movement. The result is a floating mechanical spectacle that seems suspended in time and space.
Technically, the Classique Tourbillon Sidéral 7255 is driven by the hand-wound Calibre 187M1, with 183 components and a frequency of 2.5 Hz. The tourbillon mechanism alone adds 2.2 mm of height to the 4.8 mm movement, thereby dictating the proportions of the watch’s elegant 38 mm case, crafted from 18K Breguet gold. The case is finished with the brand’s iconic fluted caseband and sapphire crystal engraved with “BREGUET 250 YEARS”.
The name “Sidéral” is no coincidence. It references sidereal time—astronomical time measured by the stars rather than the Sun. Breguet ties the watch to celestial themes not only through nomenclature but also in design. The deep blue aventurine enamel dial, speckled with copper particles, evokes a star-strewn night sky. Crafted through a meticulous grand feu technique involving multiple firings at over 800°C, each dial is unique—no two dials sparkle in quite the same way.
The aesthetic refinements don’t stop at the dial. The watch also introduces a new guilloché motif—Quai de l’Horloge—executed in both circular and linear styles across the caseback and main plate. This design pays tribute to the Seine’s curves around the Île de la Cité in Paris, where Breguet established his first workshop in 1775.
Inside, patented innovations such as the Nivachron™ balance spring offer resistance to magnetism, while the tourbillon’s elevated position amplifies the depth and drama of the timepiece. A navy alligator leather strap with a Breguet gold folding clasp completes the refined design.
With each piece individually numbered and delivered in a special red anniversary case inspired by period Breguet boxes, the Classique Tourbillon Sidéral 7255 stands as a collector’s dream and a poetic achievement in horology.
The Breguet new Classique Tourbillon Sideral, ref 7255, retails at USD 226,000.00.
