Breguet’s newly unveiled Classique Tourbillon Sidéral 7255 marks a landmark moment in the Maison’s 250th-anniversary celebrations. Limited to just 50 pieces, the timepiece pays tribute to a pivotal date in horological history – June 26, 1801 – when Abraham-Louis Breguet was granted the original patent for his groundbreaking tourbillon invention.

For the very first time in Breguet’s distinguished history, the dial of this watch is meticulously crafted from aventurine enamel. Its deep blue tone is elegantly flecked with shimmering copper particles, vividly evoking the mystery and beauty of the night sky. This intricate process demands numerous firings at exceptionally high temperatures to create a dial that is as technically impressive as it is visually poetic. Given the handcrafted nature of aventurine, no two dials are precisely alike, emphasizing the unique individuality of each piece within this highly limited production run.

At the heart of the 38mm 18K Breguet gold case beats the hand-wound Calibre 187M1, a movement architected entirely around its flying tourbillon. Raised 2.2 mm above the main plate and 0.9 mm above the enamel dial, the tourbillon appears to float—an illusion made possible by a gold base and hidden tourbillon bezel beneath the surface. The result is a mesmerizing display of suspension and symmetry: a horological constellation brought to life.
Completing the piece are hallmark Breguet touches, including a Quai de l’Horloge guilloché caseback and proprietary gold alloy, blending tradition, innovation, and celestial inspiration. For more information, visit Breguet’s official website.
