Jaeger-LeCoultre presents the Duometre Grande Complication A Grande Sonnerie, a new interpretation of Calibre 182, the Maison’s first chiming Grande Complication for the wrist. Introduced in 2009 in the Hybris Mechanica A Grande Sonnerie, Calibre 182 broke new ground in watchmaking. Incorporating a Grande Sonnerie with Westminster-style chimes – the most rarefied of all chiming mechanisms – a Petite Sonnerie and a Minute Repeater, as well as a retrograde perpetual calendar, flying tourbillon and two power reserve indicators – it was not only one of the most complicated wristwatch ever made at the time but also harnessed the innovative Duometre system (invented by Jaeger-LeCoultre in 2007) to manage the calibre’s extreme demands for energy. Due to the extreme complexity of Calibre 182, very few examples were made: with some 1,300 parts, it takes a full year only to assemble and regulate the movement and involves four phases with a total of 16,000 different operations: assembly; disassembly; corrections and cleaning; final assembly.

Now, with benefit of significant technical advances, focusing on improving the acoustic quality of the chimes and enhancing the robustness of the movement, Jaeger-LeCoultre presents a new interpretation of Calibre 182. The subject of eight patents, including six for developments specific to Calibre 182, the fully integrated movement incorporates 15 complications. The watch carries a ninth patent, for the micro-adjustment mechanism on the buckle of the alligator strap.

HARNESSING A GREAT LEGACY IN CHIMING WATCHES

The Watchmaker of Watchmakers™: For more than 150 years, chiming watches have been a particular forte of Jaeger-LeCoultre, complementing its renowned expertise in other classic complications, the Maison has developed more than 200 different chiming watch calibres, mastering all forms from relatively simple alarms to Grandes Sonneries and Westminster chimes.

After creating its first minute repeater in 1870, Jaeger-LeCoultre became known as The Watchmaker of Watchmakers™️, supplying chiming movements to many of the most exalted names in watchmaking while continually innovating to improve the mechanical efficiency, clarity and beauty of its sound, from cathedral gongs and the silent strike governor to crystal gongs, trebuchet hammers and duplex gongs. Today, the Grande Sonnerie represents the ultimate sonnerie challenge, chiming every hour and quarter hour automatically while demanding exceptional power management, precision and mechanical complexity, placing it at the pinnacle of complicated watchmaking.

CALIBRE 182: 15 COMPLICATIONS BUILT ON THE DUOMETRE CONCEPT

To create the original Calibre 182 required more than five years of intensive research and development – harnessing the Manufacture’s preceding century-and-a-half of accumulated savoir-faire in chiming watches. Offering three different ways of chiming time, Calibre 182 unites this highly complex striking mechanism with a perpetual calendar indicating the date, month and day of the week in retrograde displays and the leap years in a digital display at 12 o’clock on the dial. Like all perpetual calendars, it automatically accounts for months of different lengths as well as leap years and, if it remains wound, will need no manual adjustment until 2100 (a century year that is not also a leap year.) The calibre is enhanced by a flying tourbillon regulator and features two distinct power reserve displays – one for each of the main barrels.

Two independent energy sources: Due to the critical importance of power management, a dual-barrel movement architecture is a crucial to a Grande Sonnerie calibre. For Jaeger-LeCoultre, it was natural to build Calibre 182 on the Duometre mechanism, which it invented in 2007. This concept resolves a fundamental conundrum of watchmaking: how to maintain a perfect flow of energy to ensure precise timekeeping while adding complications that require extra bursts of energy – which inevitably compromise that regular flow. A Duometre mechanism has two barrels, each with a separate and independent gear train, housed within a single calibre and linked to a single regulating organ. In the case of Calibre 182, one barrel provides energy to the gear train that powers the time and perpetual calendar indications and the other to the gear train that drives the chiming functions, thus ensuring that their operation has no impact on timekeeping accuracy.

The barrel dedicated to the timekeeping and calendar functions provides a 48-hour power reserve; the barrel dedicated to the chiming mechanism provides sufficient power in Grande Sonnerie mode for a total of 616 notes (equivalent to seven hours and 30 minutes of continuous chiming) and in Petite Sonnerie mode for a maximum of 992 notes – equivalent to 32 hours of chiming. In addition to the standard two-barrel Duometre configuration, Calibre 182 has a third barrel. It replaces the trigger's winding motion, since the latter is replaced by a push-button on the crown.

THE CHIMES: DISTINCTIVE MELODIES WITH ENHANCED TONAL QUALITIES

Three ways to chime: Because Calibre 182 is fitted with four gongs and four hammers — instead of the usual two gongs in minute repeaters and most sonnerie movements — it is able to play four different notes (in various combinations) in the manner of the Westminster chime – the famous melody of London’s Big Ben. Adding to the distinctive character of Calibre 182, Jaeger-LeCoultre’s watchmakers made the unusual choice to have the Grande Sonnerie and the Petite Sonnerie sound the quarter-hour melody first, followed by the corresponding hours; conversely the minute repeater follows the standard sequence of hours, quarters and minutes.

616 notes, 7 and a half hours: Calibre 182’s four notes – E, C, D, G (mi-do-re-sol); one for each of the four gongs – are played in five phrases of different permutations, which are then combined in different ways to provide a unique melody for each quarter-hour. The first quarter melody comprises four notes (one phrase); the second quarter eight notes (two four-note phrases) and the third quarter 12 notes (three four-note phrases). Thus, in Grande Sonnerie mode, the hour melody comprises six phrases of four notes each – a total of 24 notes, one of the longest Grande Sonnerie melody played by any watch incorporating a striking mechanism.

Since it is fundamental to Jaeger-LeCoultre’s horological approach to continually upgrade existing calibres, further technical development of Calibre 182 has focused on the quality of the chiming melodies. In a striking watch, the shape of the gongs is crucial to the tonal purity and resonant frequency of the chime, an area in which Jaeger-LeCoultre’s chiming-specialist engineers and watchmakers constantly seek improvements. The new version of Calibre 182 has advanced acoustic performance through a combination of improvements: the gongs have been lengthened for greater resonance, their fixing and tuning have been refined and the gong shape has been modified, while the inner case body and caseback bezel are now crafted in titanium, together enhancing the overall strength, beauty and depth of the sound. Every chime is, in fact a chord and every chord has a fundamental note, supplemented by other notes. Normally, by tuning the gongs, a watchmaker can vary only the fundamental note. Thanks to the minuscule change in the gong shape in Calibre 182, it has been possible to adjust both the fundamental note and the six other notes that make up the chord, thus creating a more melodious sound.

ADVANCED MECHANISMS, IMPROVED SECURITY AND INTUITIVE OPERATION

The information behind every chime: the functional heart of a chiming watch is its information-gathering system, made up of components known as snails and racks, which translate the position of the hour and minute hands into a corresponding number of strikes. In Calibre 182, two key mechanisms control its distinctive chiming sequences and melodies.

Precision behind every strike: The ‘tour d’entraînement de sonnerie’ or ‘strike sequence governor’ is a tower-shaped mechanism that provides the mechanical information to the racks, enabling them to move into the positions required for the chimes to strike in the correct sequence. According to the selected mode, the Grande Sonnerie and Petite Sonnerie sound the melody first, followed by the hours; conversely, the minute repeater follows the standard sequence of hours, the quarter-hour melody and minutes. This tiny mechanism, visible on the dial side between 8 and 9 o’clock position on the dial, comprises 22 components but is only 6.04 millimetres high.

A second tower mechanism – nicknamed “tour infernale” by Jaeger-LeCoultre’s watchmakers because of its complexity – governs the six permutations of the four notes that create the different melodies. This stack of five snails provides the racks with the information about which of the quarter melodies should be chimed in Grande or Petite Sonnerie mode, as well as the number of hours and minutes to be struck in minute repeater mode.

Intuitive control, exceptional complexity: Because chiming mechanisms are vulnerable to damage caused by misuse, Jaeger-LeCoultre’s engineers equipped Calibre 182 with a selector mechanism to ensure that the mode chosen by the user at any given time effectively ‘disables’ the other modes. This is indicated by a display at the 6 o’clock position on the dial: M for mise à l’heure (time setting) and three chiming modes – G Grande Sonnerie, P Petite Sonnerie and S silence (which silences the automatic sonnerie chimes but allows the minute repeater to be triggered on demand). In the latest version of Calibre 182, this is supplemented by a new security mechanism for the minute repeater mode that prevents the user from triggering the chime again before the mechanism has ‘reset’ on completion of a previous chiming sequence.

The operation of the various complications is governed by three pushers – two set into the caseband and the third set into the crown – ensuring that, despite its complexity, the watch is intuitive to read and use. Calibre 182 provides energy to the minute repeater directly from the movement; therefore, rather than requiring a traditional slide in the caseband that ‘charges’ the repeater’s mainspring, the minute repeater is simply operated by the pusher in the crown. The pusher below the crown acts as the chiming mode selector, indicated on the dial by G, P or S for silent/minute repeater. The normal functions of the crown are also governed by this selector, rather than by pulling the crown into different positions: to wind the watch, the user selects S (which ensures that the automatic, en passant, chiming functions are disabled) and to set the time, the user selects the fourth mode, M – mise à l’heure. The pusher above the crown enables correction of the perpetual calendar day indication. The month and date correctors are concealed between the lugs at 12 o’clock.

A NEW AESTHETIC COMPLEMENTED BY HAUTE HORLOGERIE FINISHING

The dial of the new Duometre Grande Complication A Grande Sonnerie is more open-worked than that of its predecessor, revealing more of the beauty and intricacy of the mechanism, while the diameter of the hour-minute-calendar dial has increased by 30 percent to enhance legibility and add balance to the composition.

The principal dial-side and the hour-minute-calendar dial are decorated with dark blue-grey lacquer, which provides a visually sober contrast to the myriad moving parts and pink gold aesthetic – the latter being applied to several components, notably the five racks and their corresponding springs, visible between the 10 and 11 o’clock positions. The centre of the hours-minutes dial is sunray brushed beneath the lacquer and on the outer circle, gradient dark blue lacquer applied over a sunray guilloché provides the background for the applied 18k Pink Gold (750/1000) hour indexes.

On the periphery of the watch face, the retrograde date indication forms an arc from 7 o’clock to 11 o’clock, laser-engraved on pink gold; the retrograde displays of the days of the week and the months are laser-engraved on a pink gold inner ring on the hour-minute dial, each indicated by a small golden arrow. The two power reserve counters characteristic of the Duometre architecture are open-worked and the leap year display at 12 o’clock, provides symmetry with the chiming mode indicator at 6 o’clock. On the reverse side of the watch, the sapphire crystal case back reveals the flying tourbillon, complemented by meticulous Haute Horlogerie finishing across the movement, including sandblasting, perlage, snailing, 87 hours of hand bevelling work on 251 components, sunk rubies and screws, sunray Côtes de Genève, flat polishing, linear brushing and circular brushing – nine distinct finishes in total.

Echoing the complexity of the movement, the Grande Tradition case is made up of 60 components, combining a titanium case body with 18k pink-gold (750/1000) elements including the lugs, bezel and pushers. The pink-gold components feature a combination of microblasted and polished finishes. The Duometre Grande Complication A Grande Sonnerie is set in a 45 mm case – a remarkable feat of miniaturisation for a 1,300-component calibre – complemented by a black alligator leather strap with the Hybris series’ signature folding buckle that features a patented mechanism to enable fine adjustment for a perfect fit on the wrist.

Reaffirming Jaeger-LeCoultre’s mastery of striking watches, built on a legacy of more than 200 different chiming calibres created over the course of 156 years and epitomising its commitment to tradition through constant innovation, the new iteration of the Duometre Grande Complication A Grande Sonnerie is a pièce unique (single-piece edition).

After celebrating mechanics in its most spectacular form, then exploring the demands of competitive performance, H. Moser & Cie. and Alpine Motorsports are embarking on a new chapter in their collaboration. 

  Click , to see the large size. BIG FOTO 

This time, their focus is on the material. For the Streamliner Tourbillon Skeleton Ceramic Alpine Limited Edition, the third model born of this partnership, the Manufacture has chosen an anthracite grey ceramic case, contrasted by the blue finish of the bridges and main plate.

After the Streamliner Cylindrical Tourbillon Skeleton Alpine Limited Edition, designed around mechanics visible from every angle, and the duo comprising the Streamliner Alpine Drivers Edition and the Streamliner Alpine Mechanics Edition, created as closely as possible around professional requirements, comes the Streamliner Tourbillon Skeleton Ceramic Alpine Limited Edition, which explores another territory shared by the two houses: that of materials. 

   Click , to see the large size. BIG FOTO 

Because in motorsport, as in Haute Horlogerie, performance resides not only in architecture or mechanics. It also comes from the choice of materials, their behaviour and their ability to combine lightness, strength and precision.

Faithful to the skeletonised aesthetic sought from the outset by the members of the BWT Alpine Formula One Team, this third creation retains the complete openness onto the mechanics, allowing the movement to be seen in motion and each beat to be observed. But this time, the anthracite grey ceramic case changes the perception of the whole.

While most materials change over time, ceramic resists it. Almost scratch-resistant, unalterable, hypoallergenic and lightweight, it retains its appearance year after year. It does not oxidise. It does not develop a patina. It remains true to itself. At H. Moser & Cie., this material is making its second appearance here. 

   Click , to see the large size. BIG FOTO 

A choice rooted in conviction: certain forms deserve a material capable of standing the test of time without being affected. Since its launch, the Streamliner collection has explored fluidity. Nothing about it is angular or discontinuous. 

  Click , to see the large size. BIG FOTO 

The lines flow naturally, as if shaped by motion itself. Ceramic further enhances this aesthetic language. Alternating polished and satin-finished surfaces, the 40 mm case invites a play of light, revealing the depth of the material from every angle. It is extended by an integrated blue Alcantara strap.

  Click , to see the large size. BIG FOTO 

With this model, H. Moser & Cie. embraces its philosophy of minimalism, removing elements to reveal more. Entirely skeletonised, the dial reveals the architecture of the HMC 814 calibre in the finest detail. The bridges and main plate feature a blue finish inspired by the Alpine universe, as does the tourbillon bridge. The openworked barrel reinforces this impression of lightness and transparency.

At 6 o’clock, the one-minute flying double hairspring tourbillon appears to float in mid-air. Designed and produced in-house by Precision Engineering AG, the double hairspring improves precision and isochronism by compensating for variations in the centre of gravity generated during the expansion of the springs.

FERDINAND BERTHOUD – Chronometre FB 3SPC.4-1 Black Ceramised Titanium

FERDINAND BERTHOUDChronometre FB 3SPC.4-1 Black Ceramised Titanium 42.3 mm 2026

 Click, to see the large size. ▶ BIG FOTO 

 CHRONOMÈTRE FB 3SPC.4-1:
SHADES OF BLACK, SHAPED BY PRECISION

To coincide with Geneva Watch Days, Chronométrie Ferdinand Berthoud is pleased to present a new addition to the award-winning Chronomètre FB 3SPC collection. Housed in a contemporary black ceramised titanium case, this new model embodies the Manufacture’s respect for artisanal watchmaking traditions.

 Click, to see the large size. ▶ BIG FOTO 

When it was released in 2022, the Chronomètre FB 3SPC received widespread critical acclaim, recognised for its seemly blend of innovation, traditional craftsmanship and precision. Over the years, the FB 3 collection has won several awards in recognition of its technical virtuosity, including the Chronometry prize at the GPHG 2023.

 Click, to see the large size. ▶ BIG FOTO  

Most watches are equipped with a flat balance-spring, but the Chronomètre FB 3SPC is fitted with a cylindrical balance-spring; an approach that Ferdinand Berthoud and his nephew, Louis Berthoud, sometimes employed. Following three years of research, the Manufacture created a regulating organ comprising a variable-inertia balance, a specially designed collet and, most pertinently, a cylindrical balance-spring featuring two terminal curves.

Click, to see the large size. ▶ BIG FOTO 

Each terminal curve, one positioned at each end of the balance-spring, is shaped by hand and incorporates three bends, each created using only manual tools and a profile projector with 20x magnification. The resultant geometry of the balance-spring ensures it develops concentrically, augmenting isochronism. The Chronomètre FB 3SPC delivers remarkable precision, a fact independently recognised by the COSC, enabling this timekeeper to obtain the “Chronometer” certification.

Since the inaugural model was unveiled, Chronométrie Ferdinand Berthoud has released several expressions of the Chronomètre FB 3SPC, executed in different materials and endowed with an array of finishes. However, the Manufacture has consistently adhered to the same no-compromise approach to watchmaking, blending refined mechanisms with traditional hand-decoration techniques.

Click, to see the large size. ▶ BIG FOTO 

The latest FB 3SPC.4-1 juxtaposes modernity and artisanal craftsmanship. Housed in ceramised titanium, a lightweight material with enhanced scratch-resistance, the model is adorned in a sophisticated shade of black, destined never to fade. The case is presented in a muted finish achieved through sandblasting that serves to accentuate the appearance of the dial and movement. Interestingly, this reference features a crown guard, a first for the Chronomètre FB 3SPC, while the introduction of a black fabric strap—also unprecedented within the collection—further accentuates its contemporary spirit.

The nickel silver movement is enriched with eight forms of decoration, namely bevelling, black polishing, circular finishing, open polishing (for the jewel and screw sinks), sandblasting, satin-finishing, softening and stretching. For several components, decoration begins with the sandblasting of surfaces before additional finishes are applied.

Click, to see the large size. ▶ BIG FOTO 

Unlike some contemporary watches, this artisanal approach does not rely on a preliminary angle being applied using a machine. On the contrary, at Chronométrie Ferdinand Berthoud, the hand-bevelling is performed in the traditional way with a 45° angle deftly imparted with a knife. Once the artisan has removed any extraneous material, the bevel is filed, smoothed and polished using a series of abrasive compounds in various grades. Ultimately, gentian wood, taken from pastures near the Manufacture, is used to imbue each bevel with a brilliant sheen. The movement is endowed with 102 exterior angles and 15 inner angles, each the result of patience and craftsmanship.

Click, to see the large size. ▶ BIG FOTO 

Contrasting colours and finishes serve to enhance the visual appeal. The six bridges, visible from the dial side of the timepiece, are adorned with a vertical satin-finish. Great care must be taken when using this decoration technique as it is carried out after the bevelling: a careless movement could potentially damage the pristine angles.

Furthermore, the artisan must ensure that consistent manual pressure is applied to surfaces in order to achieve an even and harmonious result. Lastly, the vertical lines drawn on each of the six bridges positioned to the front must be aligned.

Thanks to the extension of the rattrapante function to minute and hour counters, the chronograph can measure times from one minute up to twelve hours, thus considerably enlarging the range of applications.

For instance, during a marathon, the TRIPLE SPLIT can record the intermediate times of any number of runners (for example, after 10, 20 or 30 km) and determine the winner’s time as well as a second overall time. It also covers other interesting possibilities during a journey with a classic automobile. Multiple intermediate times can be measured, for instance at specific locations such as the head of a pass or a leg of the journey. Moreover, with the option of additive time measurement, the entire driving time of the trip can be established while taking into account possible breaks or standing times.

Additionally, the TRIPLE SPLIT boasts a flyback function. It allows stopping an ongoing time measurement with only a single actuation of the pusher at 4 o’clock, resetting all currently active chronograph and rattrapante hands to zero, and instantly restarting a new measurement by releasing the pusher.

Functioning of the TRIPLE SPLIT

A split-seconds chronograph has a mechanical storage, which allows the recording of intermediate times without interrupting an ongoing measurement. Whereas a classic split-seconds chronograph can perform intermediate and comparative time measurements of up to 60 seconds, the TRIPLE SPLIT is equipped with two additional rattrapante hand pairs for measuring minutes and hours.

In the passive mode, the three blued rattrapante hands are superposed with the respective rhodiumed chronograph hands. As soon as the measurement is started by actuating the pusher at 2 o’clock, they all begin to run simultaneously and synchronously until the rattrapante pusher at 10 o’clock is pressed to freeze an intermediate time.

Then, the three blued rattrapante hands stop to display the intermediate time while the chronograph hands continue to run and measure the time. A second actuation of the rattrapante pusher causes the rattrapante hands to catch up with the chronograph hands and continue to run synchronously with them.

Lucidly structured dial design

The dial configuration, with its well-balanced hierarchy of displays, reflects the technical complexity of the TRIPLE SPLIT with exactitude. The largest display surface on the main dial is allocated to the chronograph and rattrapante seconds hands. The auxiliary dial at 4 o’clock is assigned to the precisely jumping minute counters that instantaneously advance by one increment – precisely after one minute has elapsed.

The display for the hour counters at 12 o’clock is slightly smaller while the Lange-typical UP/DOWN power-reserve indicator is located opposite at 6 o’clock: it occupies the smallest display segment and provides information on how much of the 55-hour power reserve still remains. The subsidiary seconds dial is arranged on the auxiliary dial at 8 o’clock. Within the scope of stop time measurement, the peripheral tachymeter scale makes it possible to determine average speeds over a distance of 1,000 metres.

Subtly nuanced colour composition

In the limited 950 platinum edition, the characteristic design makes its debut against a rhodié-coloured background. The grey auxiliary dials, the luminous hour and minute hands, the blued rattrapante hands alongside the red accents in the section housing the hour and minute counters as well as the UP/DOWN display create a harmonious interplay of contrast, functionality and technical aesthetics.

The case boasts a diameter of 43.2 millimetres and a height of 15.6 millimetres. The technical-elegant colour composition of a cool-toned platinum case, rhodié-coloured dial and darker, grey auxiliary dials is worn on a dark-brown alligator leather strap with a platinum deployant buckle. 

A dedicated manufacture calibre with trailblazing constructions

The L132.1 manufacture calibre is emblematic of A. Lange & Söhne’s ambition to transcend horological boundaries and emphasises the manufacture’s particular competence in chronograph construction. It accommodates the one-of-a-kind triple rattrapante mechanism – a technical masterstroke in precision watchmaking.

It assures that the three chronograph hands and three rattrapante hands accurately perform their respective functions – among which starting, stopping, catching up and resetting to zero. For the watchmakers, the complex choreography of wheels, levers, springs, clutches and jumpers requires the ultimate in expertise.

All components of the predominantly lengthy, and in part branched switching chains must be perfectly harmonised with each other: a horological marathon that hinges on perseverance, meticulousness and precision.

The stopped rattrapante hands as well as initiating the advancement of the minute counters invariably generates friction losses in the movement. The disengagement mechanism developed by A. Lange & Söhne ensures that sufficient power can be continuously delivered to the oscillation system nevertheless.

Patented in 2005, the intelligent device disengages the friction-intensive processes on the seconds arbor as well as on the minute counter arbor and thus assures precise rate stability. Because it rotates slower and hence produces substantially less friction, the hour counter arbor does not need such a mechanism. 

Exceptional complexity and mechanical beauty

The sapphire-crystal caseback allows intriguing insights into the exceptional complexity and architectural depth of the chronograph movement, elaborately finished in typical Lange style. A total of 567 minute components make up a perfectly harmonised entity.

The upper sides of the levers, springs and rockers are decorated with straight graining and the circumferential chamfers are bevelled. Chamfer polishing of the acute internal angles is especially demanding. Five gold screwed chatons on the bridges made of untreated German silver that are embellished with Glashütte ribbing and the hand-engraved balance cock round off the precision mechanical masterpiece: they exemplify that its finish is undeniably commensurate with its technical sophistication.

“Until today, the TRIPLE SPLIT plays in a league of its own,” explains Anthony de Haas, Director Product Development. “Behind the triple rattrapante mechanism for seconds, minutes and hours lies the L132.1 calibre that was entirely developed in our manufacture, one of our most elaborate and equally most beautiful movements. The depth of the architecture calls for the utmost expertise, patience and dexterity, creating an extraordinary bond between the watchmaker and the movement. At the same time, incorporating the mechanism into a movement height that safeguards the wearing comfort presented a challenge. Hence, this movement underscores our ambition to also consistently follow our own path in the field of chronographs.”
