Four years ago, Chronométrie Ferdinand Berthoud unveiled the Chronomètre FB 2RE. This collection featuring numerous innovative aspects introduced the Maison’s second movement, equipped with fusee-and-chain transmission and a one-second remontoire device. This calibre, which has won awards for its precision timekeeping performance, now reveals more of how it operates through the customisable bridges and mainplate of the new Chronomètre FB RES.

In 2020, Chronométrie Ferdinand Berthoud unveiled its second collection, the Chronomètre FB 2RE . This timepiece marked a real turning point for the Maison: the first round case, the first display with three central hands; and above all the first movement with a double regulation system combining fusee-and - chain transmission with a one-second “remontoir d’égalité”.

This movement is now offered with a completely revisited design intended to highlight its sophisticated inner workings . Formerly in domed Grand Feuenamel, the dial now features a technical combination of bridges and main plate as well as a wide opening stretching from 3 o'clock to 6 o'clock .

The latter reveals a construction with three bridges converging towards the dial centre. This geometry is directly inspired by a skeletonised table clock made by Ferdinand Berthoud circa 1775.

The similarity does not end there, as that clock displaying the hours, minutes, seconds, age of the Moon, calendar and zodiac signs was also equipped with a “remontoir d’égalité”. This timepiece in perfect working order is par t of the Maison’s heritage and is currently housed in the Ferdinand Berthoud Museum in Fleurier.

Two linear metres of hand chamfering

Exposing the movement components of the Chronomètre FB RES opens up unprecedented aesthetic perspectives, while simultaneously revealing a particularly meticulous finishing process.

Each wheel, bridge and screw is entirely hand -decorated. An extraordinary level of manual finishing has been applied in order to reveal the beauty of each component. Placed end to end, all the angles of the wheels and their bridges, as well as those revealed at the hear t of the 9 o'clock power- reserve display, represent more than two linear metres filed and polished by hand . 

   Click, to see the large size. ▶ BIG FOTO 

The finishing of the bridges and mainplate is specific to this new model named FB RES – standing in French for "Remontoir d’Égalité Squelette”.

38 personalised calibres

Thirty-eight movements will be produced in total. They will be open to customisation in a wide range of options.

The shape (round or octagonal) and material (stainless - steel, titanium, ceramised titanium and 18 - carat white, yellow, or rose gold) of the case, the colour of the inner bezel ring, the dial and the associated finishes (sandblasted or satin - brushed): in all, more than 200 variations can be simulated on an online configurator specifically created for this model.

Collectors will thus be able to bring to life variations that are unprecedented for Ferdinand Berthoud, notably including a calibre with a remontoire device in an octagonal case.

Peak precision

At the heart of this timepiece beats the Calibre FB -RES. FC, regulated by fusee- and - chain transmission and a one-second remontoire.

The purpose of this full-fledged chronometric complication is to even out the energy coming from the barrel and transmitted to the escapement. The device relies on a spring positioned between the two organs.

   Click, to see the large size. ▶ BIG FOTO 

It temporarily stores a small amount of energy, which is then delivered to the balance. The charge/discharge frequency of this buffer energy is very short: one second . It is this sequential impulse that the large central seconds hand beats off, connected to the “remontoir d’égalité” via an intermediate wheel. 

   Click, to see the large size. ▶ BIG FOTO 

It therefore advances in one-second jumps: this is a true-beat mechanism also known as a deadbeat second and generated directly by the remontoire. All these mechanical intricacies are almost entirely visible through the back of the FB RES.

“ We are fremontoire to have in our Fleurier Museum this clock made in 1775 by Ferdinand Berthoud, which reveals its movement, including a “remontoir d’égalité” ”, says Karl-Friedrich Scheufele, President of Chronométrie Ferdinand Berthoud . “Imagining a modern interpretation of this exceptional work seemed a quite logical step. This gave rise to the idea behind the FB RES collection: a skeletonised, more technical version of our own Calibre FB- RE. FC with a one -second remontoire mechanism. ”

The Chronomètre FB RES also perpetuates the Maison’s desire to offer collectors the possibility of personalising their timepieces through a wide range of options offered by this new configurator, directly accessible online on the Chronométrie Ferdinand Berthoud website.

ABOUT THE INSPIRATION

Skeletonised table clock, Ferdinand Berthoud, circa 1775

Four ring-shaped white enamelled dials for the hours (I-XII), minutes (60), seconds (60) and calendar (31); months (12) with zodiac signs; days of the week (7) and age of the moon (29 ½).

   Click, to see the large size. ▶ BIG FOTO

One main gear train and two strikework trains (hours and quarters). By means of a “remontoir d’égalité”, the main gear train supplies constant energy to the pin-pallet escapement.

The quarters strikework train (left) strikes the quarters on two bells. The hours strikework train (right) is activated after striking the quarters. It also activates the calendar.

CHRONOMÈTRE FB 3SPC.4: A LIMITED EDITION FOR ART IN TIME ANNIVERSARY

ART IN TIME Monaco celebrates its fifth anniversary. To mark the occasion, in close collaboration with the galerie horlogère, Chronométrie Ferdinand Berthoud has created an exclusive five- piece limited series of the Chronomètre FB 3SPC, available for the first time in sandblasted titanium.

   Click, to see the large size. ▶ BIG FOTO 

When Karl -Friedrich Scheufele – Co - President of Chopard and President of Chronométrie Ferdinand Ber thoud – inaugurated ART IN TIME in Monaco in 2019, he created an unusual concept: a unique space uniting watchmaking houses around the shared values of craf tsmanship, independence and originality.

   Click, to see the large size. ▶ BIG FOTO 

This pioneering space meets a growing need: to of fer collectors the chance to discover the rarest and most original creations from independent watchmaking houses. Eight of the latter joined the initiative when this exclusive space opened on the Riviera and the success of ART IN TIME is demonstrated by the fact that it now represents 24 Maisons offering highly sought - after timepieces from a number of independent master watchmakers, as well as innovative mechanical creations from well -known houses. “We are delighted with the results of our first five years in Monaco”, explains Karl - Friedrich Scheufele. “They exceed our expectations and reinforce the idea that such a place must exist in order to represent independent watchmakers with due dignity. ”

To celebrate this achievement and the gallery's fifth anniversary, Chronométrie Ferdinand Berthoud and ART IN TIME are presenting an exclusive series of five Chronomètre FB 3SPC timepieces in sandblasted titanium. Winner of the Chronometry Prize at the 2023 Grand Prix d'Horlogerie de Genève, the FB 3 collection remains the only one to date powered by a mechanical movement with a cylindrical balance-spring chronometer- certified by the COSC.

In addition to its original sandblasted titanium case, this anniversary series is also distinguished by its colour combination: its finely sandblasted, white rhodium -plated movement matches the white dial and inner bezel ring, complete with blue numerals and minutes track.

 

   Click, to see the large size. ▶ BIG FOTO 

The only things that stand out from this composition are the gear train and the escapement with its cylindrical balance -spring at 9 o'clock. Representing a horological challenge in terms of both design and precision timing, this escapement has an average rate variation of between - 1 and +3 seconds per day. This is 2. 5 times more accurate than the variation accepted by the COSC, the highly selective test to which these movements are subjected.

These five examples of the Chronomètre FB 3SPC. 4 are adorned with three interchangeable straps – in blue rubber, blue alligator leather and grey alligator leather – secured by pin buckles also made of sandblasted titanium . The back of each case bears three engravings: ‘Ar t in Time’, ‘5th Anniversary’ and ‘One of Five’ . “We are delighted to be able to of fer this special edition of the FB 3SPC Chronometer at ART IN TIME ”, adds watch galler y director Yohann Mar tinez . “Its ver y light case, rubber strap and exclusive colours bring a modern touch to this collection, renowned for its traditional approach to chronometr y. ”

FERDINAND BERTHOUD – CHRONOMETRIE FB 3SPC.1-1 White Gold

 

 

FERDINAND BERTHOUD – CHRONOMÉTRIE FB3SPC.1-1 White Gold Anniversary 2023

  CHRONOMÈTRE FB 3SPC:
A NEW EXTERIOR FOR ITS FIRST ANNIVERSARY

  Click, to see the large size. ▶ BIG FOTO  

Newly awarded the “Chronometry prize” at the GPHG 2023 after a year that has brought great success and multiple awards, the Chronomètre FB 3SPC celebrates its first anniversary with the unveiling of a new version combining a white gold case with a black movement.

  Click, to see the large size. ▶ BIG FOTO 

The first and only wristwatch with a variable-inertia balance and a cylindrical balance-spring to be officially chronometer-certified by the Official Swiss Chronometer Testing Institute (COSC), the Chronomètre FB 3SPC has been a hit with collectors and watchmaking professionals since its launch in October 2022.

  Click, to see the large size. ▶ BIG FOTO  

Voted "Best Men's Watch 2022" by Revolution magazine, then winner of the "High Watchmaking" category in the "CH24 Watch of the Year 2023" competition, the Chronomètre FB 3SPC has now added a new and prestigious award to its list of distinctions: the “Chronometry prize” at the GPHG 2023.

Click, to see the large size. ▶ BIG FOTO 

While the FB 1 and FB 2 collections followed in the footsteps of Ferdinand Berthoud's marine chronometers thanks to constant-force mechanisms, the FB 3 collection explores accuracy from a new angle: that of the cylindrical balance-spring. Particularly appreciated for its stability, this type of hairspring was favoured by the master watchmaker and his nephew Louis Berthoud in their precision timepieces.

  Click, to see the large size. ▶ BIG FOTO  

"This is how the idea of the Chronomètre FB 3SPC came about. We wanted to integrate this type of balance-spring into a wristwatch, while retaining its original purpose that was to guarantee accuracy”, explains Karl-Friedrich Scheufele, President of Chronométrie Ferdinand Berthoud. "We are particularly delighted to have been able to rise to the challenge and to see that the collection remains a great success among collectors, as confirmed by the latest award at the GPHG.”

FERDINAND BERTHOUD – Chronometre FB 3 Only Watch 2023 Unique Piece

 

FERDINAND BERTHOUD – CHRONOMÉTRIE FB 3 Only Watch 2023 Unique Piece

 HRONOMÈTRE FB 3 “ONLY WATCH”

For its second participation in Only Watch, Chronométrie Ferdinand Berthoud is offering a new version of the FB3 collection: a one-of-a-kind model presented in a patinated bronze case, a tribute to the ‘Master Watchmaker’ title granted to Ferdinand Berthoud just 270 years ago.

 Click, to see the large size. ▶ BIG FOTO  

The five one-of - a - kind models in the FB 1R Regulator collection unveiled in 2018 generated considerable enthusiasm at the time of their launch. Their bronze cases featured five different patinas, as if they had just emerged after a long stay in the underwater depths – a tribute to the world of onboard marine chronometers once developed by Ferdinand Berthoud himself.

 Click, to see the large size. ▶ BIG FOTO 

Since then, Chronométrie Ferdinand Berthoud has unveiled new movements, the latest of which powers the FB 3 collection. The conditions were therefore ripe for the creation of a model that would unite these latest developments: a one-of - a - kind timepiece in patinated bronze, driven by a balance with a cylindrical balance-spring chronometer-certified by the COSC. Thus emerged the idea of the Chronomètre FB 3 "Only Watch", which will be put up for bidding at the eponymous auction to be held in Geneva on 5 November.

One-of-a-kind anniversary model

Several months of preparation and testing were necessary to achieve the patinated bronze case of the Chronomètre FB 3 Only Watch. The colour and nuances are unprecedented and evoke to the discerning gaze the patina that naturally develops on the copper alloys of the precision and navigation instruments supplied by Ferdinand Berthoud during the 18 t h century.

 Click, to see the large size. ▶ BIG FOTO 

This patina symbolises the passage of time and celebrates an anniversary: in 1753, exactly 270 years ago, Ferdinand Berthoud received the ‘Master Watchmaker’ title, at the age of just 26. This one- of - a - kind anniversary watch will be of fered at the tenth edition of Only Watch. This is a rare opportunity, as the current capacities of the Chronométrie Ferdinand Berthoud workshops only allow for the production of around 30 timepieces in this collection per year.

Beating inside the FB 3 "Only Watch" model is the world’s only calibre with a cylindrical balance- spring of ficially chronometer- certified by the COSC, a clear tribute to the quest for precision initiated by Ferdinand Berthoud. Many months of research, testing and fine-tuning were necessary to define the number of coils and the geometry of the terminal curve at the attachment points.

Click, to see the large size. ▶ BIG FOTO

This new mechanical hand - wound movement stems from more than three years of research and development. Appearing at 9 o'clock, the three main escapement organs – the balance-wheel, pallet - lever and escape-wheel – are thus individualised, distinct and prominent. 

 Click, to see the large size. ▶ BIG FOTO   

This ample space dedicated to the regulating organ enables its operation to be admired in full, and the cylindrical balance- spring to be seen beating throughout the three-day power reserve, including through a large por thole created in the case middle at 9 o'clock.

Colour filiation

The finishing associated with the FB 3 "Only Watch" model (ref . FB 3SPC. 5) is tailored to reflect the colour codes of the 2023 edition of this charity auction. More than 100 hours of work were required to decorate the movement, which features 3N yellow gilded components. The blue colour is picked up on the gold hands with CVD treatment.

Pink hues are found on the jewels visible on the dial side. Two straps will be delivered with this one- of - a - kind model: an aged calf leather strap recalling the patina of the case; and a dark green alligator strap in harmony with the Only Watch 2023 colour char t. The caseback features a special "ONLY WATCH PIECE UNIQUE" engraving, recalling the exceptional character of this creation.
