A Considered Look
On 26 June 1801, Abraham-Louis Breguet received a patent for a regulating device he had conceived during his exile in Switzerland a decade earlier. That document, issued under 7 Messidor Year 9 of the French revolutionary calendar, set in motion 225 years of continuous refinement. In 2026, Manufacture Breguet marks the anniversary with four distinct timepieces, each approaching the Tourbillon from a different angle.
Design & Mechanics
The Classique Tourbillon 7357 is the most direct heir to Ref. 3350, the first Tourbillon wristwatch produced by the modern Manufacture in 1989. Its 35 mm case houses a 30 mm movement with no casing-ring, the dial, caseback and caseband all hand-guilloché. Two versions exist: 950 platinum (ref. 7357PT/1A/386) and 18K Breguet gold. Both carry four peripheral Bleu de France inlays, the lower two inscribed with “Brevet du 7 Messidor An 9” and “Tourbillon 225e Anniversaire”. The caseback guilloché pattern is inspired by the Dent de Vaulion, the peak that overlooks the Vallée de Joux.
The Classique Tourbillon Sidéral 7255 takes the anniversary in a different direction. First shown during Breguet’s 250th anniversary programme, it is the Manufacture’s first wristwatch with a flying tourbillon, here made additionally striking by a mysterious construction in which the drive gears are rendered invisible through anti-reflective sapphire crystal. For 2026 it gains a black aventurine Grand Feu enamel dial with green highlights and an entirely platinum case, limited to 50 numbered pieces.
Movement & Materials
Cal. 187B, developed for the 7357, retains its predecessor’s 2.5 Hz frequency (18,000 vph), the same rate A.-L. Breguet himself used, while extending the power reserve to 60 hours. A Breguet Nivachron® balance-spring with silicon pallet-lever ensures non-magnetic operation, qualifying the watch for the Breguet hallmark. The movement counts 190 components across 21 jewels.
The Tradition Tourbillon 7047 (ref. 7047PT/YY/5ZU SL) pairs the Tourbillon with a fusee-and-chain transmission, a geometry Leonardo da Vinci detailed in the 15th century. Cal. 569 runs to 499 components and 43 jewels, with a 55-hour power reserve; the chain comprises 232 links, 77 of them finished in Bleu de France. For 2026 the entire piece adopts a single-colour Bleu de France scheme including dial, bridges, titanium Tourbillon cage and rubber strap, contrasted against a glacier-blue sandblasted mainplate. Edition size: 25 pieces. The Marine Tourbillon Équation Marchante 5887 (Cal. 581DPE, self-winding, 80-hour power reserve, 4 Hz) accommodates a perpetual calendar and a running equation of time alongside the Tourbillon. Its 43.9 mm platinum case carries a translucent sapphire dial hand-painted in luminescent Grand Feu enamel with the exact positions of the constellations and Moon as seen from Paris at midnight on 26 June 1801. Each of the 25 pieces can be personalised with an alternative sky of the owner’s choice.
Why Collectors Care
The Expérimentale 1 (ref. E001BH/S9/5ZV) is the most forward-looking of the four. Cal. 7250 operates at 10 Hz (72,000 vph), the highest frequency in Breguet’s current production, and incorporates a constant-force magnetic escapement derived from research that began in the early 2000s and culminated in a patent filed on 9 November 2010. The Tourbillon cage weighs 0.6 g, measures 13.7 mm in diameter, and uses Grade 5 titanium blanks. The movement carries the Breguet hallmark in its scientific category, corresponding to ±1 second per day. The 43.5 mm 18K Breguet gold case is limited to 75 pieces, positioned as the first reference in a permanent Expérimentale collection dedicated to experimental haute horlogerie. Collectors tracking the intellectual genealogy of the Tourbillon through institutions such as the Fondation Haute Horlogerie will recognise this as a credible claim on future horological history.
The Watch in Context
Across all four references, Breguet makes a coherent argument rather than a commemorative one: that the 1801 patent was a beginning rather than a destination, and that each decade since has added a legitimate chapter. The 7357 grounds the collection in its 1989 heritage; the 7255 and 7047 extend it into visual and mechanical complexity; the Expérimentale 1 projects it into a frequency domain the original mechanism could not have anticipated. For collectors in the GCC, where several of these limited editions will be available through authorised Breguet boutiques, the principal question is which chapter of that history is most compelling to wear. Across all four, the edition sizes range from 25 to 75 pieces, and each carries a five-year international warranty. Further details on all 2026 anniversary references are available at breguet.com.

Frequently Asked Questions
What is the Breguet Tourbillon patent and why does 2026 mark its anniversary?
Abraham-Louis Breguet was granted the patent for his Tourbillon regulator on 26 June 1801, corresponding to 7 Messidor Year 9 in the French revolutionary calendar. 2026 marks exactly 225 years since that patent was granted, making it one of the most significant milestones in the history of haute horlogerie.
What movement powers the Breguet Classique Tourbillon 7357?
The Classique Tourbillon 7357 is powered by Cal. 187B, the direct successor to the legendary Cal. 558 used in the 1989 Ref. 3350. It is hand-wound, beats at 2.5 Hz (18,000 vph), has a 60-hour power reserve, and incorporates a Breguet Nivachron® balance-spring with a silicon pallet-lever.
How many pieces of the Breguet Expérimentale 1 are produced?
The Expérimentale 1 is a limited edition of 75 pieces, each numbered and hand-engraved from 1/75 to 75/75 on the caseback. It features Cal. 7250 with a constant-force magnetic escapement running at 10 Hz (72,000 vph).
What distinguishes the flying tourbillon in the Classique Tourbillon Sidéral 7255?
Unlike a conventional tourbillon, the flying tourbillon in the 7255 has its cage held only by a lower bridge with no upper bridge, creating the visual impression of a mechanism floating in mid-air. Breguet further reinforces this effect with a mysterious construction using anti-reflective sapphire crystal gears, making the drive mechanism invisible.
Can the Marine Tourbillon Équation Marchante 5887 be personalised?
The Marine 5887 is a 25-piece limited edition in which each watch can be personalised with a miniature enamel depiction of the night sky as seen from a chosen location, date and time, rather than the standard Paris sky of 26 June 1801.
