In-Depth: The Chopard Group Launches La Chronométrie Ferdinand Berthoud, And FB 1, A Marine Chronometer For The Wrist
It’s a lovely common practice nowadays (and for a long time, besides) to take the name of a celebrated watchmaker from an earlier time and assemble a brand around it. A ton of genuine watch devotees respond gravely to this, and all things considered – while we comprehend the training (custom and establishing in history is a major sell) it can appear to be constrained or even deceitful. For this situation, however, we think Chopard is doing the thing right. They’ve additionally given themselves a significant challenge, since Ferdinand Berthoud is somebody whose work was extremely assorted, and exceptionally rich, yet who likewise sets an exceptionally exclusive requirement to follow on the off chance that you want to conceivably guarantee motivation from him.
Berthoud (19 March 1727 – 20 June 1807) is thought of, alongside Pierre Le Roy (1717–1785) one of the two dads of the marine chronometer in the structure in which it was most widely utilized. (For the most part, no one nowadays truly comprehends what this implies, however consider the big picture: for a few hundred years, on the off chance that you didn’t have a marine chronometer, you had no blue water naval force and no blue water merchant marine; you had no Empire.) This may astonish you on the off chance that you’ve heard that John Harrison was the dad of the marine chronometer. The facts confirm that Harrison merits the worship in which he is held, however it is likewise obvious that his work in compact watches was both wonderful, and something of an impasse. The principal fruitful marine chronometer he made – H4 – was incredibly, complicated, and amazingly hard to make and change (it took Harrison numerous years to build up the plan and develop it, and it took English watchmaker Larcum Kendall longer than a year to make only one duplicate of H4 for testing purposes). H4 utilized a (honestly incredibly progressed) skirt escapement (the most seasoned known to horology) just as an exceptionally complex framework for compensating for the impacts of temperature on the equilibrium spring; and he additionally incorporated a remontoire . It was a practically marvelous exertion, however it was likewise out of date at a similar second it achieved its success.

Le Roy and Berthoud were peers and arch-rivals – to such an extent it’s practically difficult to write around one without referencing the other. Then again, both made and refined essentially every technical element that was important to make a high exactness marine clock that was pragmatic to create in the numbers required via nautical world powers with naval forces and merchant armadas. Le Roy’s most basic commitments were the temperature compensating balance , and the detent escapement , which is so unequivocally related to precision that it’s frequently just called a chronometer escapement. Of the multitude of escapements at any point created, the detent escapement is the one that most has the truly attractive quality of having the option to give thought process power to the equilibrium , while negligibly meddling with its regular wavering. With this kind of escapement, the equilibrium is in mechanical contact with the remainder of the stuff train just at the extremely concise second that the escapement opens the departure wheel; the remainder of the time the equilibrium swings totally “free” as watchmakers put it.
Pierre Le Roy’s Detent Escapement
Le Roy was unquestionably unbelievably brilliant and quick, however he likewise was one of those sort of prodigies who, having had a penetrating understanding into the arrangement of an issue, was maybe less drawn in with the way toward refining that knowledge. In The Marine Chronometer, Its History And Development (perhaps the absolute most by and large accommodating read out there on a technical and troublesome subject) the writer, Commander Rupert Gould, gives what’s possibly the most concise characterization of the connection between Le Roy and Berthoud, and on their work:
“The genuine improvement of the chronometer, on present day lines, might be followed back to the work of Pierre Le Roy and Ferdinand Berthoud, both of Paris . . . it might momentarily be said that Berthoud was a man of uncommon ability, who was quick to hold onto any clues from the work of others, or from his own mix-ups, and who consistently grabbed his way through a long arrangement of tests until, by a cycle of experimentation, he had created a good marine chronometer – while Le Roy was a virtuoso, who handled the issue in an altogether logical way, and delivered, with undeniably less work, a machine epitomizing all the fundamental highlights of the cutting edge chronometer. It ought to be added,” he notes wryly, “that the two men were unpleasant adversaries, and that nor was slanted to surrender to different his appropriate portion of credit.” It doesn’t reduce Le Roy’s significance at all however Gould likewise proceeds to say that, “After this preliminary (of one of his marine chronometers) Le Roy appears to have rested content with the somewhat qualified commendation communicated by the Académie (of Science) in 1769, and to have deserted . . . further exertion. He shows up, for sure to have convinced himself that his machines were unequipped for development . . .”
And, of Berthoud, Gould writes warmly, “Albeit basically the whole of his working life was passed in France, he is evenhandedly viewed in his local land as one of the best of all Swiss horologists who have accomplished such a great deal to progress both the study of horology, and the flourishing of their nation . . . he is chiefly noteworthy for his unprecedented industry, as both producer and writer – he was the most voluminous writer on horology who at any point lived – and for the great assortment of his originations . . . his deservedly incredible distinction should rest in any event as much upon his writings as his mechanisms,” Gould adds.
Berthoud Marine Chronometer, 1777
This is the inheritance the name Berthoud addresses. The introduction of La Chronométrie Ferdinand Berthoud returns, says Karl-Friedrich Scheufele, about 10 years, when Scheufele ran over a Berthoud marine check in the Chopard Museum assortment. “Frankly, I had not known about his work previously,” Scheufele reviews. “My first experience was with his nephew.” (The chronometer in question had been made by one of Berthoud’s nephews, who carried on his work after Berthoud died.) “I discovered he had been brought into the world in (the Canton) of Neuchâtel, and afterward I truly got intrigued . . . from that point on, whenever a Berthoud piece came available to be purchased, which by the way was not frequently – now even less regularly – we would be intrigued.” Scheufele examined and found that the name had just been enrolled, yet after certain arrangements, he was ready to acquire rights to the name, just as certain undertakings under early turn of events, which he advised us depended on existing developments with the expansion of the Berthoud name on the dial, which ” . . . speedily went in a drawer,” he snickers. Subsequently, working with Chopard’s technical and configuration groups, and with Chopard’s Creative Director Guy Bove (who holds a similar title for La Chronométrie Ferdinand Berthoud), both the development and a case proper for it were developed.
La Chronométrie Ferdinand Berthoud FB 1
Hopefully, you’ll locate the little history exercise relevant, in light of the fact that it gives us the information we need to assess the loyalty of La Chronométrie Ferdinand Berthoud to the work of Berthoud himself. We should begin with the case. The development’s quite intricate; the fundamental type of the case is an octagon, which is secluded in development: the flanks (3 sides each) are held to the attachment pieces for the lash by four jolts. These encase a focal, round and hollow component, and the whole thing, as per originator Guy Bove, is intended to be suggestive of the crate with its gimbal mount, in which marine chronometers were generally mounted. The overall format of the dial sees first look like a controller, however it’s not – both the moment and hour hands are in a sub-dial at 12:00, while the middle pinion is saved for the long, flimsy seconds hand. The power save – a fundamental element in a marine chronometer – is at 9:00, and the dial has been opened up to show the stuff train for the middle seconds. The explanation behind this is that the middle seconds is driven straightforwardly by the carriage of the 60 second tourbillon ; that is bizarre, as most one moment tourbs basically (and consistently) put the seconds hand straightforwardly on the pinion of the carriage. For this situation, however, it’s a homage to both a dial configuration utilized by Berthoud, just as to the soul of exactness of marine chronometers, where figuring the seconds unequivocally is fundamental. The watch, in spite of the presence of a fusée and chain, is shockingly level – 13 mm, which at a 44 mm distance across makes for something very wearable.
The development is a combination of some extremely old-school components, just as some more present day components. The materials are essentially customary; the plates and scaffolds are all of maillechort , also known as German silver – a compound regularly utilized in very good quality watches, however which, if untreated, can stain or oxidize effectively whenever took care of inappropriately, so it takes additional consideration in assembling and get together. The focal point of consideration is the tourbillon – type FB-T.FC, which is 35.5 mm in measurement, and 8 mm thick, has a one moment tourbillon, with gold balancing weights on the carriage, and as we’ve just referenced one somewhat unordinary include is that as opposed to put a seconds hand on the pinion of the carriage, it’s driven straightforwardly by the carriage. The architecture is perhaps the most old fashioned components of the watch: it’s what’s known as a “column and-plate” plan, in which the development top and base plates are isolated by columns (made, for this situation, of titanium.) This is really the most seasoned sort of development in horology, going right back to the absolute first spring powered convenient clocks from the start of the 16th century. There are not many developments made in this way nowadays (one of the lone different examples I can consider random being Moritz Grossmann, whose manufactory we visited a year ago ). La Chronométrie Ferdinand Berthoud has exploited the open flanks of the development by setting “openings” into the side of the case, that allow a view of the fusée and chain.
Before we get into the fusée, however, a quick word on the power save . It’s a somewhat uncommon plan, not regularly found in present day watchmaking – rather than the typical differential stuff train, which is associated with the heart barrel, there is a cone which rises and falls as the fountainhead barrel turns. An antenna switch with a ruby roller on it is redirected by the cone as it goes all over, and the switch thusly changes the situation of the hand showing the excess power save. This was a framework utilized by the late Dr. George Daniels as well.
Since the fusée is such a vital component in the FB 1, we should discuss what it is, and why it is. The fusée is a gadget for ensuring the measure of torque going from the heart to the stuff train stays as consistent as could be expected. Here’s how it works. There’s a chain (or in the days of yore, catgut rope) interfacing the fountainhead barrel to the fusée cone, which has a twisting depression running start to finish. The notch is wider at the base than at the top. When you wind the watch, you’re unspooling the chain from the barrel onto the fusée cone, and as the watch runs, the fountainhead barrel maneuvers the chain back onto itself. This makes the fusée cone turn. The fusée cone has a stuff as a base, and that stuff conveys power to the stuff train, and hence, to the escapement and equilibrium. The motivation behind the fusée in a watch, or clock, is to give the heart a more noteworthy and more prominent influence advantage as it unwinds and weakens.
One issue with a fusée, coincidentally, is that when you wind it, you’re drawing the chain onto the fusée, which means power is done going from the heart barrel, to the fusée, to the stuff train, and the watch stops. To forestall this, John Harrison concocted a “looking after power” framework which comprises of a little spring inside the fusée that keeps power going to the equilibrium during winding. Another arrangement is to mediate a differential between the crown wheel and the arbor of the fusée, so torque is as yet conveyed to the stuff train even while winding. This is the arrangement utilized by both the FB 1, and by Lange, in the Richard Lange Tourbillon Pour Le Mérite, about which, more in a moment.
Fusée and chain: how it works
Mainspring barrel and fusée cone, type FB-T.FC
The absolute first clock escapement ever – the skirt – was incredibly touchy to power varieties. As watchmaking progressed, progress in heart barrel configuration, just as advances in equilibrium spring and escapement configuration, ultimately made the fusée out of date on the whole yet the most noteworthy accuracy, long-running spring wound clocks: marine chronometers, where they proceeded being used through the 1970s.
There are incredibly, few wristwatches with both a tourbillon and a fusée and chain, and the purpose behind this (other than the impressive additional expense and complexity) is that both take up quite a great deal of room. Placing in a fusée fundamentally implies multiplying the measure of room you need than if you’d recently made them fountainhead barrel, and the tourbillon’s carriage essentially expands the measure of room you need too; it likewise for the most part implies that the equilibrium is more modest than it would have been on the off chance that you hadn’t utilized a tourbillon. On top of all the other things, the chain is a major genuine annoyance to make. It isn’t by and large a norm off-the-rack part, and manufacturing the parts, just as the hand-get together important, help guarantee the fusée and chain stay a lot of a niche component in current watchmaking.
Offhand I can consider just two different watches that combine a tourbillon with a fusée; one is the Breguet reference 7047 La Tradition , and the other is the A. Lange & Söhne Richard Lange Tourbillon Pour Le Mérite , which unquestionably places the FB 1 following after some admirable people. It’s worth taking note of, incidentally, that a steady power device needs to be recognized from a consistent power escapement. The previous incorporates the remontoire d’egalité and the fusée; genuine consistent power escapements are incredibly uncommon and to date, just one brand has placed one out of a wristwatch. There is likewise the wildly surprising Zenith Christophe Colomb Hurricane , yet this, carefully talking, isn’t a tourbillon; all things considered, it utilizes a gimbal suspension framework to keep the escapement and equilibrium flat at all times.
One other uncommon element of the fusée and chain framework in FB 1 is that the fusée and heart barrel are “hanging” – they’re attached distinctly to the base plate of the watch. (Typically, both would be sandwiched, alongside the stuff train, escapement and equilibrium, between the two development plates.) This game plan is the subject of a patent application, and it has two favorable circumstances: it allows a superior view of these two components, and, too, it allows the development to be compliment. “Hanging” heart barrels are, incidentally, a significant component in extra-level watchmaking when all is said in done; one widely utilized and well respected development in which they are found is the Jaeger-LeCoultre type 849.
So how does the whole thing add up? Well, above all else, there is the expense: the FB 1, which will be offered in two adaptations (white gold with titanium, and rose gold with dark artistic, 50 pieces each) is valued at €220,000, or around $245,600 at the hour of distribution. This is generally commensurate with its competition (the Lange in white gold is $212,900 and the Breguet is evaluated at $175,600 in rose gold, however I presume real customers for these watches are not, to say the least, propelled by comparison shopping dependent on value.) The FB 1 additionally has the longest power hold of these three watches (56 hours; the Lange offers 36, and the Breguet, 50). The Lange is the most slender of the three, at 12.2 mm, while the FB 1 comes in at 13 mm, and the Breguet, 15.95 mm. When all is said in done, the designing choices are clear for each watch, and include choosing how much to accentuate power hold versus slenderness. Each has its own exceptionally unique tasteful, and the FB 1 has a combination of contemporary flavor and exemplary plan signs that set it apart from some other comparable contribution accessible right now.
The second issue – or rather, question – that the FB 1 raises has nothing to with cost, and everything to do with what it, and the Chopard Group, desire to achieve. Having the option to assess and, if it’s as you would prefer, appreciate such a thing requires a specific degree of knowledge – about the historical backdrop of watchmaking all in all; about what a portion of its most fundamental issues are and were; and about who a portion of its most significant players were. It’s conceivable, obviously, to be pulled in to this watch for different reasons – the style, the part it plays throughout the entire existence of the Chopard Group, etc. Yet, we trust that as these watches discover their way into the market, that those keen on them, and in watches like them, discover them a motivation to comprehend somewhat more about how they became, and about the extraordinarily industrious, centered, and mentally skilled men who made them.
Berthoud and his peers were nothing not exactly the craftsman researchers who, against truly overwhelming chances, figured out how to interestingly wring truly precise timekeeping from simply metal, steel, and valuable gemstone direction (and truly horrible oil – goose oil, anyone?) and if La Chronométrie Ferdinand Berthoud figures out how to make us all delay a second when we put on our watches toward the beginning of the day, and consider exactly what number truly splendid people needed to commit their lives to tackling unfathomably hard-headed issues to make wearing a watch conceivable, it will have accomplished an incredible arrangement in fact. Also, value notwithstanding, and capacity to own, or not, notwithstanding, that is how mindfully made super top of the line watches can be delighted in by everybody.
La Chronométrie Ferdinand Berthoud FB 1 is offered in either white gold with titanium accents, or rose gold and dark earthenware. Development, type FB-T.FC, hand-wound one moment tourbillon with fusée and chain, COSC affirmed chronometer. 50 bits of each rendition, accessible worldwide, through select retail locations (they will not be sold in Chopard boutiques).
