The Breguet Classique Tourbillon Sidéral has captured the attention of haute horlogerie fans since its debut during the brand's 250th anniversary. Now, as Breguet celebrates the 225th anniversary of the tourbillon, the maison presents a new platinum iteration, reference 7255PT, limited to just 50 pieces. This edition features a striking black aventurine enamel dial, replacing the previous deep blue, and delivers a fresh aesthetic that many collectors may find even more compelling.

A Familiar Yet Innovative Movement

At the heart of the Sidéral lies the calibre 187M1, an evolution of the calibre 558 that powered Breguet's first wristwatch tourbillon in 1989. This movement retains the signature off-centre dial layout and full-plate architecture visible through the sapphire case back. However, the tourbillon itself is a flying design, meaning it lacks an upper bridge, giving the illusion of suspension. The two-armed cage rotates clockwise, a detail that invites closer inspection. This mechanism pays homage to the 2007 Classique Tourbillon Messidor 5335, which used a sapphire crystal drive wheel, but the Sidéral simplifies the construction by removing the upper support entirely.

Design and Dial: A Cosmic Black

The platinum case measures 38 mm in diameter with a fluted band and soldered lugs, maintaining a classic Breguet profile. The new black enamel dial is not merely painted; it is a genuine grand feu enamel creation that mimics aventurine glass. Tiny copper flecks are embedded in the enamel, resembling stars against a deep-space backdrop, hence the name 'Sidéral'. The dial is paired with a black-coated white gold chapter ring and applied wordmarks in rhodium-plated gold. The result is a more subdued, elegant look compared to the blue version, with the black backdrop allowing the regulator and tourbillon to take centre stage.

Calibre 187M1: An Engraved Masterpiece

The manual-winding calibre 187M1 beats at 18,000 vibrations per hour and offers a 50-hour power reserve. It is crafted from gold, a rarity in modern watchmaking, and decorated with 'Quai de l'Horloge' guilloché executed on a hand-operated straight-line engine. The floating bridge for the lower tourbillon support features a barley corn motif cut with a rose engine. The movement also includes a Nivachron hairspring with an overcoil, a nod to Breguet's historical contributions to watchmaking, and offers antimagnetic properties. The tourbillon bridge is rhodium-plated and polished, enhancing the visual depth of the mechanism.

Limited Edition and Market Position

With a retail price of CHF 223,000, the Breguet Classique Tourbillon Sidéral competes with high-end time-only tourbillons like the A. Lange & Söhne 1815 Tourbillon. While Breguet's craftsmanship is impeccable, the brand's cachet may not yet match some German rivals. However, for collectors who appreciate historical significance and technical prowess, this limited edition offers a unique opportunity.

Final Thoughts

The Breguet Classique Tourbillon Sidéral in platinum is a tour de force of traditional watchmaking. Its flying tourbillon, exquisite dial, and gold movement make it a worthy addition to any serious collection. The black dial, in particular, lends a modern edge while remaining true to Breguet's classical roots. If you are in the market for a rare, beautifully executed tourbillon, this watch deserves serious consideration.
