  History written in the present tense

Following the Breguet gold version, awarded the Aiguille d’Or at the GPHG in 2025, the House unveils a new platinum interpretation of the Souscription, faithful to the spirit of the emblematic model conceived by Abraham-Louis Breguet at the end of the 18th century.

More than two centuries later, this historic timepiece continues to inspire the Manufacture through reinterpretations that combine watchmaking heritage with contemporary craftsmanship.

An expression of subtle elegance

With its platinum case, this new version offers a presence that is both understated and refined. A rare and precious metal, platinum accentuates the purity of the Souscription’s design and lends a distinctive elegance to this iconic model. In the purest tradition of exceptional leather goods, Breguet is unveiling an original presentation box to mark its 250th anniversary. Inspired by the red Moroccan leather cases once used by A.-L. Breguet to protect his precious creations, this box, in lightly grained calf leather, features gold hot embossing bearing the inscription “BREGUET 250 YEARS”, which is accompanied by the individual serial number of the timepiece inside.

A contemporary interpretation that naturally continues the story of a watch that has become one of the symbols of Breguet’s heritage. Its soft, rounded silhouette designed with an aesthetic and “philosophical” concern shaped over time, marks a real difference from traditional watch boxes. The opening mechanism, faithful to the techniques used in A.-L. Breguet’s time, is based on a simple, elegant pushbutton, while its hinge is plated with Breguet gold. The interior is lined with refined blue fabrics housing the watch in a vertical position, thus optimising space and evoking the spirit of pocket watches.

"This watch is the link between what we wish to share of the history of Breguet and our desire to perpetuate this history going forward."

Gregory Kissling, Breguet CEO.

 

A nod to the first Breguet “logo” in the form of an escutcheon (a type of shield often seen in coats of arms) adorns the underside of the case. Much more than just a watch box, it is a collector’s item, a symbol of timeless heritage and watchmaking expertise that spans the ages. 

Grand Feu enamelling 

Grand Feu enamelling consists in applying enamel and firing it at very high temperatures until a stable, luminous surface is obtained.

This expertise demands exceptional mastery, as each firing can either reveal the dial or permanently compromise it.

A radiant face with classic feature  

Dressed in immaculate enamel, the dial symbolises the refined aesthetic intended by the master watchmaker. Based on simplicity and contrasts, it is easy to read. At its centre is a unique, steel, open-tipped Breguet hand, which has been flame-blued and curved entirely by hand. 

  Click, to see the large size. ▶ BIG FOTO  

Its tapered tip hovers over the famous, slightly inclined Breguet Arabic numerals, as well as the circular “chemin de fer” (railroad track) with its specially designed sectoring indicating the hours and the 5, 10, 15 and 30-minute markings. The numbers and minute markers are in black, petit feu enamel, the same as the Breguet signature placed at 12 o’clock.  

  Click, to see the large size. ▶ BIG FOTO  

Depending on the light, the inscriptions “Souscription”, the unique serial number and the secret signature appear discreetly between the centre of the dial and 6 o’clock. Generalised on the original Souscription watch, this signature served to authenticate the work of the Breguet workshops and fight against counterfeiting. It is produced, as it was in A.-L. Breguet’s day, using a precision tool equipped with articulated arms: the diamond-point pantograph, which makes it possible to delicately engrave this guarantee of authenticity into the enamel.

This face, with its classic features, is protected by a sapphire crystal with a “chevé” profile. This innovation is also the work of A.-L. Breguet. This format, thinner and less domed than those then in vogue, has a relatively flat surface that gently curves towards the edges to blend harmoniously into the case, which was unprecedented at the time. This distinctive shape, like Breguet numerals and hands, has become part of the vocabulary of contemporary watchmaking. 

Hand engraving

Hand engraving consists in incising the material using traditional tools to create decorations, inscriptions or motifs. Each gesture calls upon the artisan’s expertise and gives the piece a unique character. 

    Click, to see the large size. ▶ BIG FOTO  

The case measures 40mm in diameter and 10.8 mm in thickness, with a classic three-part construction. The lugs are integrated within the case middle, with no soldered straight lugs, and the sides are finely brushed rather than fluted, a deliberate choice to make the watch sleeker and more ergonomic.

A polished, domed bezel frames a sapphire crystal with a “chevé” profile, a reference to another Breguet innovation: a crystal thinner and less domed than others, with a relatively flat surface and a bevelled edge.

The back also has a sapphire crystal, framed by a “Quai de l’Horloge” guilloché motif, and water resistance is 30 metres. The dial keeps the same design, display and materials as the gold edition. 

Bevelling

Bevelling consists in chamfering and then polishing the edges of the movement components.

Its 144 components and 21 jewels fit into a diameter of 35.6 mm and a height of 5.7 mm, with a large central ratchet held by an oversized triangular bridge, two stepped bridges for the first wheel and balance wheel, and two smaller triangular bridges for the gear train, in the spirit of the Tradition watches.

It beats at 21,600 vibrations per hour, or 3 Hz, with a non-magnetic Nivachron balance spring with a Breguet overcoil, classic five-spoke Breguet wheels and a modern anti-shock device shaped like the old pare-chute. A single barrel delivers a 96-hour power reserve.

BREGUET – CLASSIQUE Grande Sonnerie Métiers d’Art 1905 Edition

 

BREGUET – CLASSIQUE Grande Sonnerie Métiers d’Art 1905 Tourbillon, Repeater 18K Breguet 56.5mm Gold 250th Anniversary Edition - 2025

Breguet announces the Classique Grande Sonnerie Métiers d’Art 1905. A highly complicated pocket watch featuring Métiers d’Art craftsmanship, it is equipped with a grande and petite sonnerie as well as a minute repeater with magnetic regulator for all striking scenarios, with a regulator-style time display. All powered by a tourbillon. This special timepiece, in Breguet gold with Bleu de France accents, will only be produced on request.

The name of A.-L. Breguet is closely associated with a number of inventions that have remained at the forefront of contemporary watchmaking for over two centuries: the gong spring (1783), the shock absorber (1790), the Breguet balance spring (1795) and the tourbillon (1801), among others.

The Classique Grande Sonnerie Métiers d’Art 1905 celebrates these major inventions, incorporating them into a movement comprising 532 components – the first of its kind that Breguet has produced in over 20 years. This authentic Grande Complication features a Grande Sonnerie mechanism and an on-demand minute repeater, as well as a tourbillon and a regulator-style display to emphasise its quest for precision.

First assembled in the raw, then fully decorated and put into operation, it requires more than six months of assembly.

The quintessence of the Breguet spirit, it features exceptional finishes derived from the master’s heritage: guilloché, grand feu enamel, engravings and a secret signature made with a pantograph. This piece is protected by two patents that echo two inventions by Breguet: the gong spring and the gold gong spring.

Another distinctive feature is its Bleu de France colour, emblematic of Breguet’s adopted country, which won over the court of Versailles. This shade, introduced at the instigation of Louis XIV, can be found on the shop fronts of Place Vendôme, including that of Breguet, where this timepiece was officially unveiled.

The end of an exceptional year

In 1775, A.-L. Breguet opened his workshop on the Quai de l’Horloge in Paris. The manufacture that now bears his name celebrates the heritage of the great watchmaker, who was personally associated with the most important milestones in his craft.

Click, to see the large size. ▶ BIG FOTO 

His aesthetic codes (guilloché, engraving, fluted case, hollowed-out hands, etc.) and techniques (tourbillon, perpetual winding, chronometric seconds, shock absorber, spring-loaded gong, etc.) have left an indelible mark on the industry, a quartermillennium that followed his work.

The quest for precision

The Classique Grande Sonnerie Métiers d’Art 1905 encapsulates much of this extraordinary journey. It encompasses four major components. First, the quest for precision. To this end, the timepiece is equipped with a tourbillon. The process was patented by Breguet in 1801 and has never really been surpassed.

Click, to see the large size. ▶ BIG FOTO 

Since being transposed to the wristwatch, having originally always been designed by Breguet for pocket watches, the Classique 1905 accurately recalls with an obvious sense of historical consistency. Today, it is visible at 4:30 with a blue upper bridge. The balancing of the cage by weights is faithful to the process invented by Breguet himself.

The timepiece also features a regulator-style display. It has three independent hands on three different sectors: the off-centre hour, the central minute, and the second at 4.30 o’clock via the tourbillon. This arrangement contributes to excellent readability and precision, with each indication having its own area and reference points. This guarantees the reading precision, in line with Breguet’s fundamental quest.

A timeless aesthetic

Second component: the affirmation of Breguet codes. Many maisons have drawn inspiration from them, but the Classique 1905 aptly recalls the talent of their creator. This is true of the dial decoration.

As early as 1775, Breguet disregarded the ornamental trends in watchmaking, many of which struggled to break away from the ornate spirit of the Baroque period. Instead, the great watchmaker established a clear, luminous, simple and refined style. He demonstrated with exceptional skill that precision, legibility and elegance could be combined in a coherent and harmonious whole.

Click, to see the large size. ▶ BIG FOTO 

To achieve this, the Classique 1905 takes its cue from the master watchmaker, with a dial divided into sectors. Each sector has its own finish to accentuate its legibility and individuality. At 12 o’clock, the hours are off-centre. The Breguet hand sweeps over a grand feu enamel dial. The Arabic numerals are in petit feu black enamel. The master’s signature is twofold: visible at the top, secret at the bottom, engraved flush with the enamel by a pantograph.

Click, to see the large size. ▶ BIG FOTO 

The central minutes touch a finely guilloché pattern. The widespread use of this art in watchmaking is also associated with Breguet. The motif engraved here using a traditional guilloche machine is a horizontal Quai de l’Horloge, which can also be found on the side of the case.

It is inspired by the shapes of two Parisian islands surrounded by the Seine, Île Saint-Louis and Île de la Cité, where Breguet’s first workshop was located. The Quai de l’Horloge still exists today in the 1st arrondissement of Paris. Discerning enthusiasts will note the exceptional length of this blued central hand, which hovers over a dedicated minute track.

The seconds can be read on the blued hand fixed to the centre of the tourbillon cage.

Ode to the arts and crafts

The third component of the Classique 1905 celebrates the artistic crafts so dear to the Breguet manufacture.

The work is crafted in Breguet gold and engraved by hand. The Seine and its course are represented by a Bleu de France enamel engraving. This colour is attested on enamel tact watches from the early 19th century; this colour, still present today, belongs to the history of France and especially to the history of Paris.

Click, to see the large size. ▶ BIG FOTO 

The inside of the lid bears the individual number of the piece, engraved by hand.

It should be noted that Breguet’s craftsmen have taken the decoration to its peak by guilloché-engraving the edges of the covers with a Quai de l’Horloge motif. The three-dimensional geometry of the edges of the covers is not usually guilloché but polished or engraved, as decoration machines can only produce patterns on flat or slightly curved components.

Click, to see the large size. ▶ BIG FOTO 

Here, Breguet has developed a unique guilloché technique that allows three-dimensional components to be decorated.

The back of the watch is entirely guilloché (Quai de l’Horloge) and enamelled (Bleu de France). When opened, it reveals a full view of the movement. To reinforce its horological mastery, it is constructed in reverse: instead of having the striking mechanism on the dial side (where it takes its information), it has been moved to the back. Breguet’s watchmakers have therefore designed a movement whose aesthetic appeal is as important as its technical excellence.

Click, to see the large size. ▶ BIG FOTO 

The complete quadrature of the minute repeater and grande sonnerie mechanism can be seen. Each component is decorated by hand: drawn lines, bevelling, stretching, encapsulating. The guilloché work on the striking barrel bridge features the Petit Trianon motif, created especially for the 250th anniversary of the Manufacture, based on the interlacing patterns visible at the Palace of Versailles. Only the blue hammers are visible on the dial side.

Click, to see the large size. ▶ BIG FOTO 

This timepiece comes with a Breguet gold chain, the fastenings of which are also guilloché with the Quai de l’Horloge motif.

Finally, it should be noted that the Classique 1905 will be delivered in an exceptional case, also unique, made from the last remaining wood available from Marie-Antoinette’s authentic oak tree. The venerable tree, under which the Queen used to walk, was planted in 1681 and survived until it was badly damaged by the great storm of 1999 and finally felled in 2005.

Crafted in marquetry and entirely handmade following the geometry of the French Pavilion at the Petit Trianon estate, each element was carefully selected from the heart of the wood, chosen for the natural variations in its colour as it ages. A true work of craftsmanship that extends the experience and philosophy of the Classique 1905.

Click, to see the large size. ▶ BIG FOTO 

This case also features a resonance plate made from wood sourced from the Risoud forest, located in the heart of the Vallée de Joux, to enhance the sound of this watchmaking masterpiece.

It is said that this wood is used in the construction of the finest violins, and that only one tree in ten thousand offers resonance of absolute perfection.

The pursuit of innovation

In 2025, the Breguet manufacture finally continued the tradition of innovation begun by A.-L. Breguet in 1775. This was the fourth component of the Classique Grande Sonnerie Métiers d’Art 1905, equipped with a magnetic regulator, the result of Breguet’s R&D.

The regulator’s function is to constantly smooth out the frequency of the hammers’ action, i.e. the tempo at which the notes are played. It must always be the same, regardless of the number of hours, quarters and minutes, and the energy level of the dedicated barrel.

Most regulators are mechanical. The one in the Classique 1905 is magnetic and particularly ingenious. In many ways, this device resembles an electric generator.

Click, to see the large size. ▶ BIG FOTO 

Made of metal, the rotating arms are placed between networks of magnets fixed on either side of the regulator. As they rotate in this magnetic environment, current loops are induced inside the conductive arms. This is the principle of Foucault currents, discovered in 1851, a contemporary of Antoine-Louis Breguet and Louis-Clément Breguet. As it forms, this current opposes the magnetic field of the magnets. These current loops in turn induce a magnetic field that opposes the magnetic field of the magnets, thus creating an electromagnetic brake.

As a result, the faster the rotation, the greater the resistance. Conversely, the slower the rotation, the weaker the opposition. The result is a device that ensures a rotation that tends to be constant.

Click, to see the large size. ▶ BIG FOTO 

The centrifugal force moves the regulator’s conductive arms outwards, placing them under the magnets, which tends to slow down the rotational movement. At lower speeds, springs pull the arms back inwards to reduce the intensity of the electromagnetic brake.

Click, to see the large size. ▶ BIG FOTO 

What’s more, the system is completely silent and contactless. It thus respects the three striking modes of the Classique 1905 (Grande Sonnerie, Petite Sonnerie and Minute Repeater, the latter of which can be activated on demand even when the watch is in Silent mode).

BREGUET – Experimentale 1 Constant-Force Magnetic 10 Hz Tourbillon Edition

 

BREGUET – Expérimentale No. 1 Constant-Force Magnetic 10 Hz Tourbillon 43.5mm Gold 250th Anniversary Edition - 2025

The first chapter in the brand’s new exploratory R&D line

Manufacture Breguet announces the creation of a line that will incorporate the latest innovations from its Research and Development department. Named “Expérimentale”, it is initially being introduced through a Marine wristwatch featuring an innovative and daring design. This timepiece crafted in Breguet gold is equipped with the very first high-frequency (10 Hz) tourbillon with a magnetic escapement and delivering constant force to the balance. It is certified by the Breguet hallmark.

R&D have been core to numerous Breguet creations for 250 years. This spirit was in-stilled by Abraham-Louis Breguet himself, who was responsible from 1775 onwards for most of the watchmaking innovations of that era: the tourbillon, the perpé­ tuelle watch, the natural escapement, the constant-­force escapement, the “obser-vation” seconds counter (which gave rise to the chronograph), the shock absorber, the Breguet balance-spring with its ter-minal curve, the gong-spring (for chiming watches),­ the first wristwatch, etc. 

Click, to see the large size. ▶ BIG FOTO 

To give shape to this approach based on continuous progress, the Manufacture deci­ ded to develop a collection in parallel with its existing ones and named Expérimentale­. This series of special timepieces pays trib-ute to A.-L. Breguet’s creations that all underwent­ an experimental phase.

BREGUET - No. 4691

This experimental collection is designed to showcase the brand’s latest technical and aesthetic developments. It offers a glimpse of what Breguet watchmaking will look like in the future. For collectors, it is also an opportunity­ to be among the first to ac-quire high-end timepieces in strictly limited series, of which the scientific content will be developed in subsequent collections. 

Expérimentale 1, pioneering by nature

While the first timepiece in this new collec-tion marks the final chapter in Manufacture Breguet’s 250th anniversary celebrations, it also represents the first chapter of its future. An inaugural creation whose purpose is to pave the way for the House going forward.

BREGUET - No.3424

The Expérimentale 1 is not a spontaneous creation, stemming instead from many years of R&D work carried out behind the scenes and that has given rise to the current watches, notably the Classique, Tradition, Marine and Type XX collections. The Expérimentale programme aims to highlight this R&D shedding light on the entire field of horology through its work on materials, electromagnetism, vibratory­ mechanics­ and acoustics. Science in the broadest sense of the term, connecting with design. 

Highlighting remembrance

For this first instalment, Breguet has fulfilled two objectives. The first, fundamental goal underpinning all technical end eavours is the quest for precision. The second is to build a bridge between legacy and the future. This approach is being rolled out as part of the House’s 250th anniversary celebrations. Highlighting the historical significance of the Expérimentale 1 seemed an obvious choice.

Click, to see the large size. ▶ BIG FOTO 

BREGUET - No.1252 

These ties with the past are expressed by making this timepiece part of the Marine collection. The aim is to recall that, after his appointment to the Paris Bureau des Longitudes in 1814, A.-L. Breguet was awarded the title of Horloger de la Marine Royale (Watchmaker by appointment to the Royal Navy) by Louis XVIII. 

Click, to see the large size. ▶ BIG FOTO  

BREGUET - No.2292

This distinction was the most prestigious a watchmaker could possibly receive, as the very notion of maritime horology required scientific expertise. The Expérimentale 1 represents a continuation of this tradition, showcasing technical breakthroughs that are already shaping the future of Haute Horlogerie. 

Inspired design

The Expérimentale 1 is based on several complementary aesthetic foundations in-teracting to form a unique and harmonious whole. For this first opus, the designers drew inspi-ration from the history of the Marine collection, with L’Expérimentale featuring some of its codes: a sporty case, close-set central lugs, a rubber strap (interchangeable for the first time), as well as utmost attention devoted to readability – notably enhanced by all-luminescent indications.

BREGUET - No. 4691

From a historical perspective, it echoes the aesthetic codes of Reference 3448, partic-ularly in terms of its dial display and move-ment architecture. Furthermore, the Expérimentale 1 echoes the Reference 1747 model created in 1997 to mark the 250th anniversary of A.-L. Breguet’s birth.

Pocket marine chronometer Breguet No. 3448,
sold in 1820 to the astronomer Alexis Bouvard

This establishes a natural connection with the Expérimentale 1, unveiled in 2025 to celebrate the 250th anniversary of the birth of the Manufacture that has borne his name since 1775. Another obvious link is that the 1747 was the first wristwatch to feature a regulator display in Breguet’s recent history – and the likewise regulator-type Expérimentale 1 is its legitimate successor.

Click, to see the large size. ▶ BIG FOTO 

The lineage dates all the way back to the authentic Marine Chronometer No. 104 by A.-L. Breguet. At the time, the great watch-maker was exiled from France, where the Revolution was raging. The piece was start-ed in the temporary workshop he had set up in Le Locle. No. 104 was Breguet’s first known marine chronometer, just as the Expérimentale 1 is Breguet’s first pure R&D model; finally, No. 104 was the first to use Arabic numerals (extremely rare at the time), which are also picked up on the Expérimentale 1. 

The quest for precision

On a technical level, the choice of distinctive characteristics contributing to enhanced accuracy was just as obvious. Precision was and remains the driving force behind Breguet’s innovation. It was the reason for almost all the innovations introduced by A.-L. Breguet, a watchmaker who spent his entire life perfecting the art of horology.

It should be noted that Breguet filed very few patents during his lifetime, as they were rarely needed at the time. Two of them did however leave an indelible imprint on their era. The first was filed on 9 March 1798 and related to constant force, while the second registered on 26 June 1801 was intended to protect the tourbillon. Two centuries later, Manufacture Breguet is following in the great watchmaker’sfootsteps by pushing these two fundamental areas of endeavour up a further notch on the tourbillon and the constant-force escapement.

Together with the magnetic escapement, they form the heart of the Expérimentale 1. Like A.-L. Breguet’s original creations, its components, have been designed to bring real added value to the product. The Expérimentale 1 heralds a new era for watchmaking, in which the Manufacture will showcase the fruits of its watchmaking and scientific research.

Setting the terms of the horological equation

The quest for accuracy cannot be reduced to one sole problem with a single solution, instead combining at least three variables. The first is the consistent amplitude of the balance. The latter is located downstream from the barrel, whose torque decreases as the power reserve is depleted.

It is therefore inherently very difficult for the balance to maintain a constant amplitude if the energy it receives is not consistent. The second is the influence of Earth’s gravity, which particularly affects the entire regulating organ (balance and hairspring), thereby impacting its performance.

The third factor is shock resistance. All con-temporary watches are subjected to accel-erations that are multiples of the Earth’s gravitational acceleration expressed in “gs”. More dramatically, they can be subjected to impacts – including those involved in sim-ply placing a watch on a hard surface. Every impact and every movement affects the regular running of the watch – and hence impairs its precision.

Breguet’s first-ever 10 Hz tourbillon
with constant-force magnetic escapement 

Since the early 2010s, the Manufacture has continued to perfect its mastery of the magnetic field. While this has now been extended to the escapement, its founding principle remains the same: to create a carefully controlled magnetic field and interactions.

This involves two escape-wheels each equipped with a magnetic track, at the centre of which beats a pallet-lever with likewise magnetic pallets. The idea is to take cues from constant-force escapements. Below a certain operating torque, the tourbillon stops very quickly, while above this threshold, the balance oscillates at its maximum amplitude.

This new escapement also makes it possible to decouple the impulses transmitted to the balance from the rotation of the escape-wheel and hence from the rest of the gear train. Unlike in a Swiss lever movement, the inertia of the tourbillon cage has almost no influence. By decoupling these two functions, Breguet has been able to create a tourbillon with a 10 Hz oscillator in such dimensions, also giving free rein to design choices, for example by offsetting its balance from the cage’s centre of rotation. 

 Technical description of the tourbillon

 Compared to most traditional tourbillons operating at 2.5 Hz, this represents a fourfold increase. This 10 Hz frequency is even significantly higher than most classic Swiss lever escapement watches without tourbillons, almost all of which run at 3 or 4 Hz. The 10 Hz tourbillon with magnetic escapement is therefore more stable and more accurate than most contemporary wristwatches.  The Expérimentale 1 wristwatch is certified by the Breguet hallmark in the “Scientific” category, meaning it has a guaranteed accuracy of +/- 1 second over a 24-hour period.

The construction of the escapement mechanism is also unusual. Between its two escape-wheels equipped with a magnetic track, an intermediate stop wheel ensures that the device does not suffer any unwanted jumps. Most of the other tourbillon components are non-magnetic, in order to avoid any interaction that could interfere with its smooth running. The balance-spring is made of silicon, the fixed fourth wheel of LIGA (NiP12) and the other components of titanium or nivagauss.

 Avant-garde aesthetics

The Expérimentale 1 is housed in a 43.5 mm-diameter Breguet gold case, a size inspired by the standards of the Marine collection. In terms of design, the timepiece is inspired by the pocket watch No. 3448, picking up the latter’s key characteristics with a regulator-style display and symmetrical movement while taking them to a new level by merging front and back. The Expérimentale provides full visibility, thanks to a sapphire dial providing a view of the entire movement.

The regulator-type display features hours at 6 o’clock, offset minutes and seconds on the tourbillon at 12 o’clock. Already tried and tested by A.-L. Breguet back in his day, this layout ensures greater legibility and also contributes to accurate timekeeping.

The Expérimentale 1 also features a patented twin barrel, like the Breguet no. 3448, but this time on two series-coupled levels, each consisting of a double spring separated by a sapphire spacer, arranged on either side of the minutes axis at 3 and 9 o’clock respectively. This double-sprung mechanism serves to optimise energy management in relation to the space available.

Finally, most of the traditional characteristics of a Breguet watch are present: a double-stepped fluted caseband, six close-set lugs – of which two are dedicated to the interchangeability mechanism and the four others are facetted, alternating between sandblasted blued and satin-brushed finishes as well as a blue ALD-treated Breguet gold inlay – blue open-tipped hands enhanced with Super-LumiNova®, a secret signature on the sapphire dial and Breguet numerals. Above and beyond these features, the aesthetic vocabulary of the Expérimentale 1 has been completely reinvented.

A 21st century creation 

The first thing to note is the construction of the solid gold bridges, whose soft curves have given way to sharp angles. Their surface is satin-brushed, while the angles are hand-finished and mirror-pol-ished to accentuate the rigorous geome-try of their design. Breguet gold, combined with the navy blue coating, reveals itself in all its complexity with a blend of warmth, brilliance and intensity. The blue hue of the barrel springs is also a first for Breguet.

The sapphire dial rests on four gold pillars. It displays the hours, formed by three linked luminescent circles. The large peripheral minutes track sur-rounds the chapter ring at 6 o’clock, while the tourbillon appears to escape from its confines, sitting freely at 12 o’clock – two-thirds inside the minutes track and one-third above it.

It is here, directly above the Breguet gold mainplate, that the Manufacture has chosen to place the Expérimentale 1 cartouche, symbolically crowning the entire composition – and more particularly its 10 Hz tourbillon with a constant-force magnetic escapement. The latter consists of a large rounded-off polished bridge, with the small seconds dial resting at its centre.
