The Breguet 225th anniversary tourbillon collection landed on June 26, 2026 — the exact date on which Abraham-Louis Breguet was granted his tourbillon patent on 7 Messidor Year IX of the French Revolutionary calendar, or June 26, 1801. To mark exactly 225 years since that patent, Breguet unveiled four new tourbillon watches: the entirely new Classique Tourbillon 7357, a 35mm revival of the brand's first tourbillon wristwatch; the Classique Tourbillon Sidéral 7255PT with its flying "mysterious" display; the Tradition Tourbillon 7047PT with its fusée-and-chain mechanism in a striking Bleu de France colourway; and the Marine Tourbillon Équation Marchante 5887PT, the most complex watch in Breguet's current catalogue. Prices run from $184,800 to $325,200.
This is not a routine anniversary launch. The Breguet 225th anniversary tourbillon collection coincides with a broader design overhaul under CEO Gregory Kissling — new lug architecture, new strap materials, new movement decorations — making these four watches genuinely pivotal within the brand's modern story. For our full Breguet archive, see the Breguet collection overview. Here is everything you need to know.
Why June 26, 1801 Matters: The Tourbillon Patent
Abraham-Louis Breguet (1747–1823) did not invent the tourbillon concept on June 26, 1801 — he had been working on it since at least 1795, after fleeing Paris during the French Revolution and spending time in watchmaking centres in Neuchâtel and Le Locle. What June 26, 1801 marks is the formal grant of his ten-year patent for the mechanism in France.
The tourbillon was conceived to solve a specific, practical problem of its era: the balance wheel and balance spring of a pocket watch — when held vertically in a jacket pocket, as pocket watches always were — are subject to the constant downward pull of gravity. That gravitational influence introduces a predictable error into the watch's rate. Breguet's solution was to enclose the entire escapement and balance assembly in a continuously rotating cage that completes one full revolution per minute, averaging out the gravitational errors across all orientations. The mechanism demanded extraordinary miniaturisation and engineering precision for its era. Breguet himself acknowledged that the tourbillon regulator had taken him "many years of work."
The Breguet 225th anniversary tourbillon collection draws directly on this history — each of the four new watches represents a different chapter of how that original mechanism has evolved across 225 years of manufacture practice.
Watch 1: Classique Tourbillon 7357 — The 35mm Revival
The Classique Tourbillon 7357 is the only genuinely new reference in the Breguet 225th anniversary tourbillon launch — and it is the one that carries the most historical weight. It is a direct successor to the Ref. 3350, the first Breguet tourbillon wristwatch, launched in 1988 with a movement designed by Daniel Roth during the brand's Chaumet-era revival. At just 35mm — one millimetre smaller than the original 36mm reference — it is an act of deliberate restraint in an era when complications almost universally grow larger.
The case sits under 10mm tall in both available metals: 18k Breguet gold (Breguet's proprietary variant of 4N rose gold) and platinum. The solid gold guilloché dial features Clous de Paris pattern at the centre and a barleycorn motif around the edge, with Breguet's characteristic Arabic numerals. The movement is Caliber 187B — an evolved descendant of the original 3350's calibre, now antimagnetic, fitted with a silicon pallet-lever and gold hands, and decorated with a new guilloché motif inspired by the Dent de Vaulion mountain near the Breguet manufacture in the Vallée de Joux. The tourbillon is positioned a few tenths of a millimetre below the dial plane, adding visual depth. A sweeping design change: the classic Breguet bishop-staff lugs are gone, replaced by modern curved lugs attaching to suede leather straps — the brand's new material direction under Kissling.
The 7357 joins Breguet's permanent collection. Prices: $184,800 in Breguet gold, $203,300 in platinum.
Watch 2: Classique Tourbillon Sidéral 7255PT — The Flying Mystery
The Classique Tourbillon Sidéral 7255PT was first introduced in Breguet gold as part of last year's 250th anniversary collection — it was, historically, the first Breguet wristwatch to offer a flying tourbillon. For the Breguet 225th anniversary tourbillon, it returns in platinum with a black aventurine enamel dial, the copper flecks suspended in the vitreous enamel catching light like stars against a dark sky.
The "mysterious" quality of the display comes from the construction of Caliber 187M1: the tourbillon's lower bridge is made entirely of sapphire glass, making the mechanical connection between the gears and the cage appear invisible. The tourbillon protrudes 2.2mm above the mainplate and 0.9mm above the dial surface, floating in apparent mid-air. All dial elements — Breguet numerals, hands, chapter ring — are rhodium-plated for tonal coherence with the platinum case. The movement beats at 18,000 vph with a 50-hour power reserve.
At 38mm × 10.2mm, this is the second-smallest watch in the anniversary quartet. Limited to 50 pieces at CHF 223,000 / $294,400.
Watch 3: Tradition Tourbillon 7047PT — Fusée-and-Chain in Bleu de France
The Tradition Tourbillon 7047PT is the boldest watch in the Breguet 225th anniversary tourbillon collection — a machine-aesthetic piece dressed in a palette of glacial and cobalt blue that references the French tricolore without stating it directly.
The movement, Caliber 569, pairs the tourbillon with one of watchmaking's oldest precision mechanisms: a fusée-and-chain transmission. The fusée is a tapered cone connected to the barrel by a miniature chain; as the barrel unwinds and its force diminishes across the 55-hour power reserve, the chain progressively transfers the drive from a wider to a narrower portion of the cone, maintaining constant torque to the escapement throughout. The mechanism traces to the late Renaissance — Leonardo da Vinci documented the concept — and almost no modern watchmaker incorporates it in an automatic context. Breguet does so here, combined with a one-minute tourbillon, under three cantilevered open-worked bridges that fill the dial.
The colourway: a glacier-blue sandblasted mainplate, Bleu de France bridges, chain, and Grand Feu Bleu de France enamel dial. The caseback is equally impressive — geometric, structured, and revealing the full depth of the movement. Strap: Bleu de France rubber with glacier blue topstitching, matching the dial's palette. Case: 41mm × 16mm in platinum. Limited to 25 pieces at CHF 246,300 / $325,200 — the most expensive reference in the anniversary collection.
Watch 4: Marine Tourbillon Équation Marchante 5887PT — The Grand Complication
The Marine Tourbillon Équation Marchante 5887PT is Breguet's most complex modern wristwatch, and the Breguet 225th anniversary tourbillon has given it its finest dial yet. The case measures 43.9mm in platinum — the largest in the quartet — and can be ordered with a matching platinum bracelet, itself hand-engraved and engine-turned.
The dial is the story. It is executed in grand feu sapphire enamel with luminous pigments — it glows in the dark, revealing the constellations and position of the moon exactly as they appeared from Paris on the night of June 26, 1801, the day the patent was filed. Star-shaped hour markers and anchor-shaped hands complete the celestial and maritime iconography. All complications are displayed on the front dial: a running equation of time (the "marchante" function — a hand that moves continuously in real time, not a discrete display, showing the live difference between civil and true solar time), a perpetual calendar, and a tourbillon regulator.
Caliber 581DPE uses a peripheral rotor on the movement side, its platinum mass engine-turned and hand-engraved with an 18th-century depiction of the Royal Louis, a French navy flagship of the kind Breguet supplied instruments to during his lifetime. The bridges are inlaid with Breguet gold and engraved with the same motif. Price: not yet confirmed at time of publication — check Breguet's official website for current availability.

Frequently Asked Questions
Q1. What is the Breguet 225th anniversary tourbillon collection?
Four new platinum tourbillon watches unveiled on June 26, 2026, exactly 225 years after Abraham-Louis Breguet was granted his patent for the tourbillon on June 26, 1801.
Q2. How many Breguet 225th anniversary tourbillon watches are limited editions?
Three: the Sidéral 7255PT (50 pieces), the Tradition 7047PT (25 pieces), and the Marine 5887PT (edition details TBC). The Classique 7357 joins the permanent collection in both Breguet gold and platinum.
Q3. What is the cheapest Breguet 225th anniversary tourbillon?
The Classique Tourbillon 7357 in 18k Breguet gold at $184,800 is the entry point of the Breguet 225th anniversary tourbillon collection.
Q4. What is the fusée-and-chain mechanism in the Tradition 7047?
A constant-force device that maintains even torque to the escapement throughout the power reserve, using a miniature chain between the barrel and a tapered cone. The mechanism ensures consistent accuracy from the first hour to the last — Leonardo da Vinci documented the concept; Breguet combines it with a tourbillon.
Q5. What does "marchante" mean in the Marine Tourbillon?
The word means "walking" or "moving." The equation marchante is a running, real-time hand that continuously shows the live difference between mean solar time (civil time) and true solar time — unlike conventional equation-of-time displays, which advance discretely.
Q6. What is the significance of the June 26, 1801 date?
It is the exact day Abraham-Louis Breguet received his ten-year patent for the tourbillon from the French government, recorded as 7 Messidor Year IX under the French Revolutionary calendar then in use.
The Bottom Line
The Breguet 225th anniversary tourbillon collection is a coherent curatorial act rather than a marketing exercise. Each of the four watches represents a distinct chapter of the brand's history with the complication — a compact revival of the 1988 original, a flying mystery with aventurine enamel, a fusée-and-chain machine dressed in cobalt blue, and a grand complication whose dial encodes the precise night sky of the patent day. The Bleu de France colour thread running through the Tradition 7047PT and the Marine 5887PT gives the collection a shared visual identity without forcing uniformity.
