In-Depth: A Guide to Every Equation of Time Watch by A.-L. Breguet

Abraham-Louis Breguet (1747-1823) stands among the most revered names in horology, celebrated for innovations that shaped modern watchmaking. While his tourbillon, self-winding mechanism, and anti-shock system are widely acknowledged, his work in astronomical timekeeping, particularly equation of time (EOT) watches, remain one of Breguet’s most intricate yet less-explored achievements. With 2025 marking the 250th anniversary of his birth, this guide offers the most comprehensive study of every known EOT timepiece made during his lifetime, including pocket watch no. 160 “Marie Antoinette”, expanding on our prior analysis of the complication (in parts I and II). No. 160 as pictured at the recent exhibition in London’s Science Museum. Image – Baruch Coutts Looking at the stars Breguet operated in an era where precision timekeeping was dictated by astronomy, and his workshop, positioned at the heart of Paris’s scientific and commercial networks, was uniquely placed to serve scientists, navigators, and royalty who required accurate solar and mean time readings. Rather than settling on a single method for displaying and correcting the EOT, he explored multiple mechanical solutions, refining some while revisiting earlier ideas when necessary. His approach does not follow a strictly linear evolution but instead reflects a dynamic cycle of innovation, mechanical experimentation, and adaptation. Breguet’s cam-driven system with feeler to indicate EOT, as found in pocke...

Time Through the Ages, Part 2: Abraham-Louis Breguet’s Genius of Invention

Editor’s Note: Time Through the Ages is a four part series written by Andrew Canter, member of the British Horological Institute, Alliance of British Watch & Clock Makers, and the British Watch & Clock Makers Guild. In this second installment, Andrew examines the life and career of Abraham-Louis Breguet, inventor of the tourbillon and many other important watchmaking advancements. For more from Andrew, check out his work at Mr. WatchMaster.  Abraham-Louis Breguet (1747–1823) was a designer, inventor, and watchmaker. Being a master craftsman in the field of watchmaking earned him a prestigious clientele that included Louis XVI and Marie Antoinette, alongside other international nobility, and the elegance and technical innovations of his designs were considered the height of style and fashion. Portrait of Abraham-Louis Breguet. Image courtesy of Manufacture Breguet Breguet was born in Neuchâtel on the 10th January 1747, but it was in Paris that he spent most of his productive life. He is credited with the development of the successful self-winding perpétuelle watches, the introduction of the gongs for repeating watches, the first shock-protection for balance pivots and of course the tourbillon. Every watch that left his workshops demonstrated the latest horological improvements in an original movement, mostly fitted with lever or ruby-cylinder escapements that he perfected. He was a great entrepreneur and marketed his magnificent watches brilliantly. Perhaps his most ...

Emmanuel Breguet Talks Fakes In The Time Of Abraham-Louis Breguet And Much More

Jan Lidmaňský interviewed Emmanuel Breguet, vice president and head of patrimony at Breguet. He chatted with this direct descendant of Abraham-Louis Breguet about fakes in the time of Breguet, which watch is still missing from the Breguet Museum’s collection, how many pieces the company has acquired at auction over the last 20 years, and much more.

Breguet Tradition Automatique Seconde Rétrograde 7097 And Abraham-Louis Breguet Souscription Pocket Watch Deconstructions: What The Naked Watchmaker Didn’t Reveal – Reprise

The Breguet Tradition collection, as exemplified here by the Tradition Automatique Seconde Rétrograde 7097, does just what it says on the label: provide tradition. And it does that very well as Ian Skellern illustrates in a comparison with an original 200-year-old Abraham-Louis Breguet Souscription pocket watch.

A Historical Tour of Abraham-Louis Breguet’s Paris

If there is one place to retrace the footsteps of Abraham-Louis Breguet, it is in Paris, where the master watchmaker lived, worked and built a reputation as one of the most innovative horological minds of all time.

Complicated Collectors: Edgar Mannheimer

London, 1965. Christie’s had arranged the third and final part of the Sir David Salomons Collection for sale — a sequence of Breguet watches assembled by the Victorian baronet whose obsession with Abraham-Louis Breguet had produced the most important English-language study of the watchmaker’s work. When the bidding closed, one man had bought every lot in the catalogue. Continuing our ongoing Complicated Collectors series, Edgar Mannheimer left an indelible mark on watch collecting. He was 40 years old, and had settled in Zurich a decade earlier with nothing but the instincts he had developed in the post-war black markets of Germany. He was not a collector in the sense that he did not keep what he bought. What he did, with a consistency and conviction that separated him from every other figure in the mid-century horological trade, was understand, ahead of the market, what something was worth. The Salomons lots were subsequently divided between two collectors. It was, in miniature, a portrait of how Mannheimer operated: he absorbed the risk, resolved the complexity, and left his clients with the watches. Neutitschein and Auschwitz Edgar Mannheimer was born on December 23, 1925, in Neutitschein, Moravia, into a family whose presence in the town was visible and established. His father ran Marsmalz, a confectionery business prominent enough to operate the community’s first delivery van — a small but telling detail about the family’s position within a world where Je...

A Fresh Palette for the Breguet Tradition

Breguet refreshes its Tradition collection for 2026 with new colourways and expanded grand feu enamel dial options across five references, building on the momentum of the brand’s 250th anniversary year. The line-up spans four automatic variants of the Seconde Rétrograde and one manually wound GMT, all underpinned by the architecturally distinctive cal. 505 that has defined the collection since its 2005 introduction. Initial thoughts Inspired by an original Abraham-Louis Breguet’s montres à tact pocket watch from the late 18th century, the Tradition collection, released in 2005, was Breguet’s first major new model family under Swatch Group management. The central barrel placement and unusual gear train arrangement perfectly captures the essence of the original pocket watches, and this aspect of the design remains as recognisable and distinctive as ever, despite the a growing number of independent watchmakers that have introduced watches with a similar layout. In fact, the cal. 505 is so successful as a contemporary interpretation of Breguet’s work that a variation of it was adapted for use in the award-winning Classique Souscription 2025 introduced last year. For 2026, the Tradition collection has been slightly refreshed with modern colourways and more grand feu enamel dial options. The five new models include four automatic variants of the Seconde Rétrograde, one of which features a diamond-set bezel, and one manually wound reference with a dual-time complicatio...

In Depth: Breguet No. 160 Montre d’Or

Abraham-Louis Breguet’s No. 160 exists first as legend. The standard account describes a secret commission for Marie Antoinette, incomplete when she faced execution, requiring forty-four years to finish. Theft, recovery, mystery, and royal romance: the narrative contains all the necessary elements of mythology. Yet this fame is recent. From its 1783 inscription in the order books through the 19th century, the watch remained largely unknown outside the Breguet workshop but for a few private collectors. Only when Sir David Lionel Salomons acquired it, nearly 140 years later, did the wider horological world learn of its existence, thanks to his careful cataloging and the watch’s public exhibition in 1923. Salomons gave credit to Breguet’s mastery on a scale previously unrecognised, establishing No. 160 as the supreme example of complicated watchmaking and the prime masterpiece of its maker. Sir David Lionel Salomons’s 1921 work on Breguet and the collection he assembled seems to be the first source to mention Marie Antoinette. Image SJX composite – Sotheby’s Subsequently, many sources have reported that the commission demanded every known watch complication and that no time constraints or limits were placed on its design or cost. The workshop records, however, tell a story that differs from both obscurity and legend. No. 160 appears in the 1783 order books as three words: “No. 160, Montre d’Or.” The entry stands alone, anonymous, unexplained and without cont...

Complicated Collectors: Dr Eugen Gschwind

The dinner in Basel had reached the stage where the porcelain was being cleared, but the tension at the table remained heavier than the silverware. Dr Eugen Gschwind, a man who wore his erudition as comfortably as his tailored suits, watched his guest with the predator’s patience that had defined his four decades of collecting. Across from him sat George Daniels, the English horologist and watchmaker who had single-handedly dragged the concept of the handmade watch out of the grave of history. Daniels was brilliant, notoriously opinionated, and, according to some, firmly convinced that he was the spiritual reincarnation of Abraham-Louis Breguet. François-Paul Journe´s 3/84 pocketwatch, Dr Gscwind´s first commission. Image SJX composite – F.P. Journe Gschwind liked Daniels. He championed the Englishman’s genius, yet remained too dogmatic to ever buy his work. He had famously toasted Daniels at a society dinner as the ‘greatest living watchmaker,’ only to follow it with the dry, smiling addendum: ‘But only the second-best watchmaker who ever lived.’ Tonight, however, was not about jests. It was the culmination of a long-simmering technical argument. For years, Gschwind had chided Daniels about his reliance on the 15-second remontoir d’égalité. To Daniels, this mechanism, which rewound a secondary spring every quarter-minute to smooth out the torque of the mainspring, was the ultimate solution to the problem of isochronism. Gschwind viewed it was a compro...

Hands On: Breguet Expérimentale 1

The Expérimentale 1 debuted last year as the capstone to the first quarter-millennium of the house of Breguet. We attended the launch event and shared immediate hands-on impressions, but watches like this don’t come along every day, or even every year, so it’s worth a fresh look now that some time has passed and the dust has settled. On paper, the Expérimentale 1 arguably represents the highest form of the mechanical watch. To understand the technical details of what makes the watch so groundbreaking, this in-depth analysis should be considered required reading. In short, the cal. 7250 housed within introduces the first-ever contactless mechanical escapement that simultaneously achieves two feats that Abraham-Louis Breguet himself toiled to accomplish throughout his entire career, namely, an oil-free escapement and stable amplitude. The Expérimentale 1 delivers both, and more. That said, as a wristwatch the Expérimentale 1 is tantalisingly imperfect owing to its polarising design. In fairness, this arguably says more about the difficultly of communicating technical breakthroughs to a non-technical public than it does about the design process at Breguet. It could also be the result of Breguet learning lessons from its own past. A modern (Marine) chronometer The Expérimentale 1 is most notable for its novel escapement and what it signals about the future direction of the brand, but it’s also worth analysing the updated Marine-style case, which is the most challeng...

Buying Guide – Honouring the Tourbillon with Six Showstoppers

Since its invention by Abraham-Louis Breguet in 1801, the tourbillon has remained one of the most mesmerising mechanisms in watchmaking. Often regarded as a complication in its own right, despite not actually indicating anything most of the time, it is a very complex and extremely precise testament to the maker’s abilities, whoever it is. Rotating […]

Hands On: Breguet Equation of Time Pocket Watch No. 2492

A rare Breguet pocket watch with retrograde perpetual calendar and equation of time illustrates the evolution of the house from its founder’s era to the early 20th century, blending historical motifs with modern concessions. Made in 1932, Breguet No. 2492 is one of just four known examples from a series of equation of time movements produced over nearly five decades by the legendary workshops of Victorin Piguet. In short, it’s a watch with one foot in the 19th century and one in the early 20th. The transitional nature of the watch evidently resonated with collectors, as the watch recently sold for CHF241,300 at Phillips’ Geneva auction in November, some 20% above its high estimate. Context It might be surprising, but Abraham-Louis Breguet’s unexpected death in 1823 had no immediate effect on the firm’s output. The firm produced well over a hundred watches each year, which required a staff of skilled workers, as well as A.-L. Breguet’s family, who understood what a Breguet watch was, and could build one without being managed by the man himself. However, with the old guard’s retirement, and general decline of Parisian watchmaking, things slowly changed. After the Breguet family sold the firm in the late 19th century, turning instead to the more lucrative business of aviation, the firm’s output strayed from A.-L. Breguet’s vision, abandoning Breguet’s signature design language for a medley of styles catering to specific markets. During this time, the brand...

Hands-on – A Closer Look at the Breguet Classique Tourbillon Sidéral 7255

Unveiled on 26 June 2025, a nod to the date Abraham-Louis Breguet secured a patent for his gravity-defying tourbillon (26 June 1801), the Tourbillon Sidéral 7255 takes his groundbreaking regulator on a fascinating ride through time and space. Released for the brand’s 250th anniversary celebrations, the Breguet Classique Tourbillon Sidéral 7255 pays homage to its illustrious […]

Breguet’s Magnificent Magnetic Expérimentale 1

Breguet concludes its 250th anniversary with the brand’s most forward-thinking watch, the Expérimentale 1 that boasts a magnetic, true constant force escapement. Equipped with a frictionless escape wheel and pallet lever driven by magnetic forces, the movement runs at 72,000 beats per hour, or 10 Hz – arguably making the Expérimentale 1 the ultimate Breguet chronometer. Impressively innovative with its use of silicon, magnets, and clever teeth geometry, the limited edition watch also marks the start of the Expérimentale line, a collection that will serve as a platform to debut new complications, technology, and designs. Initial thoughts While some might have been expecting an updated Sympathique, Breguet instead surprised with perhaps the most advanced wrist-borne mechanical chronometer in modern watchmaking. Taking cues from Abraham-Louis Breguet’s own “constant force” escapements, Breguet today harnessed the power of permanent magnets and unique teeth geometry to built a genuinely friction-less, constant torque escapement. In fact, the new escapement appears to be the only truly frictionless and constant force escapement on the market today.  Magnets have been employed in escapements in the past, but this approach was historically unreliable. Breguet appears to have discovered the right formula for a magnetic escapement. Several functioning prototypes were on show at the launch event. Moreover, Breguet chief executive Gregory Kissling explained that the ma...

First Look – The Breguet Experimentale 1, With 10Hz High-Frequency Tourbillon and Constant Force Magnetic Escapement

Innovation spirit and inventiveness have always been part of Breguet, specifically as its founder, Abraham-Louis Breguet, was responsible from 1775 onwards for so many of the watchmaking innovations of that era: the tourbillon, the perpétuelle watch, the natural escapement, the constant­-force escapement, the shock absorber, the Breguet balance-spring with its terminal curve, the gong-spring… In […]

The Greatest Horological Masterpieces of All Time: Breguet’s Marie Antoinette Watch and Its Impact on Horology

A series of features identifying the most extraordinary mechanical masterpieces in history, blending precision, innovation, and craftsmanship. We all have our favourite timepieces either in our collection or those incredible horological masterpieces that have been invented or created through the ages. This series will showcase examples from the previous centuries up to the present day and look at the importance and impact on modern day timekeeping. Few watches in history have captivated the world quite like Breguet No. 160, often referred to as the Marie Antoinette Watch. Commissioned in 1783, this masterpiece of horology was intended as the ultimate expression of luxury, precision, and mechanical complexity. Crafted by Abraham-Louis Breguet, the legendary Swiss watchmaker, it would take over 44 years to complete, long after Marie Antoinette’s tragic execution and Breguet’s death. Marie Antoinette was an Austrian princess and the wife of King Louis XVI. Born on the 2nd November 1755 in Vienna, Austria, she was the 15th child of Empress Maria Theresa of Austria and Emperor Francis I, Holy Roman Emperor. She grew up in the lavish Schönbrunn Palace centre of the court of Vienna, surrounded by wealth, music, and political intrigue. Marie Antoinette with a Rose. Elisabeth Louise Vigée Le Brun, 1783.

Watch Hands: A Guide to the 14 Most Popular Styles

Watch hands are more important to a timepiece's design than you might think. A watch can have the most beautiful dial in the world but it isn't really a watch unless it tells you the time. And while the wide world of watches does offer some intriguing exceptions to the classical analog style that's been established for centuries, the vast majority of timepieces still adheres to that formula: two main hands, one for the hour, one for the minute, sometimes joined by a third for the seconds, pointing to the time on a numbered ring. All watch hands do essentially the same jobs, so one might assume that little thought and creativity goes into designing and crafting such a utilitarian element of horology. One would be mistaken, however, since watchmakers over the years have created numerous hand types, each of which imparts its own distinctive character to a watch's overall aesthetic. Here is a rundown of a dozen of the most significant styles used on watches today, and a little about where each came from and how it got its name. [toc-section heading="Breguet Hands"] Designed by Abraham-Louis Breguet, founder of the eponymous luxury watch maison and inventor of numerous horological devices including the tourbillon, Breguet hands made their first appearance on a watch in 1783, Traditionally crafted in blued steel, they are recognizable for their slim shafts and “hollow moons” near the tips. An indicator of classically elegant design, and often paired with Roman numerals, or...

Friendships matter in life, and what better way to celebrate the bond between two of watchmaking’s greatest individuals than with a tribute watch? Bringing together Abraham-Louis Breguet’s renowned tourbillon escapement and John Arnold’s beloved fusée-and-chain system, lovingly replaced with a constant force mechanism, the Constant Force Tourbillon 11 made a deep impression when launched earlier […]

Hands On: Breguet Four-Minute Tourbillon No. 1890

In the coming weekend, one of the most important watches of this auction season will go under the hammer at Sotheby’s Breguet’s 250th anniversary thematic sale November 9 – Breguet no. 1890, a pocket watch with tourbillon and natural escapement made by the firm by Breguet while Abraham-Louis Breguet himself still helmed the company. The gilt dial with a regulator-style layout might seem familiar – the recent Classique 7225 reproduces this dial design. In fact, Breguet no. 1890 isn’t the only watch in this style; it belongs to a series of pocket watches all equipped with a four-minute tourbillon and échappement naturel from the early 19th century that were among the finest watches of the time. Breguet built just eight four-minute tourbillons with natural escapement, all of which thankfully survive, and only three with gold dials. King George III ordered the most famous example – almost identical to this watch – during the Napoleonic wars. For context, that would be like Churchhill (who owned a Breguet himself) ordering an A. Lange & Söhne watch during the Second World War. As such, it was signed Recordon, Breguet’s London agent, to disguise its French origins. Whirling About Regulator Almost 225 years ago, the French Ministry of the Interior granted A.-L. Breguet a patent for his most famous creation, the tourbillon – a clever exercise in lateral thinking. For a mechanical watch to keep the same time across all vertical positions the combined balance, st...
