Introducing The Ferdinand Berthoud Chronomètre FB 2RE
We’ve done a few Editor’s Picks effectively this year, and this most recent watch from Ferdinand Berthoud sort of represents the issues with picking top choices before the year is in reality finished (but, we’ve qualified them all with “up until now,” or if nothing else I think we have). The Ferdinand Berthoud Chronomètre FB 2RE is a watch about which there is an incredible arrangement to say, and inside which there is an extraordinary arrangement to see, however more than everything else, it is, similar to its archetypes , a terrific rise of mechanics to workmanship, and a show that finished an adequate level of over the top focus, simply specialized arrangements can rise above the absolutely specialized and become … all things considered, we’ll see what they can become.
If you have been following Ferdinand Berthoud’s watchmaking in the course of the most recent couple of years, you will have noticed some essential similitudes across the different models. As a rule, the watches have shared a controller type design, with an enormous focal seconds hand; an octagonal case with oval windows for the situation band; a more modest sub-dial for the hours and minutes; and in the development, a fusée and chain (with both a coasting fusée cone and origin barrel, with no upper extensions) just as a stopworks system on the fountainhead barrel. The watches are complicated albeit the components are, in the event that you need to be severe about it, not complications essentially, but instead managing gadgets (that is for every individual who gave me trouble about picking a tourbillon for Favorite Complication! ), and a portion of the couple of genuine complications in the watches have been a moon-stage and a force hold. They have cut, notwithstanding their complexity, to a to some degree stark tasteful, and this is in accolade for the watchmaker from whom the company takes its name – the acclaimed French chronometer creator, Ferdinand Berthoud (1727-1827), of whom the late George Daniels once composed (maybe with an eye on the familiar proverb that it takes one to know one) that he had, “an exceptionally high assessment of his own work.”
Ferdinand Berthoud’s Marine Clock no. 6, which went through ocean preliminaries in 1768.
The specific motivation for the FB 2RE was Berthoud’s Marine Clock No. 6. That clock sits in a perfectly put forth tube shaped defense with a gimbal framework, and the case and gimbals lay on a base fitted with an enemy of stun spring. The clock likewise has a two-level dial, which was, thusly, the motivation for the dial for the FB 2RE.
Two or three things leap out at you in case you’re comfortable with Ferdinand Berthoud’s past watches. In the first place, the case is not, at this point octagonal, however round (albeit the horizontal windows have been held). The second is that this is the main Ferdinand Berthoud watch which doesn’t utilize a controller format. All things being equal, there are regular hour, moment, and seconds hands, all on a similar pivot. The actual dial is genuinely complex in development. It’s made in two sections – there is a focal level plate, and an external, domed circle, and both are grand feu enamel over enemy of magnetic steel. The fairly considerable looking case (43mm x 14.30mm) is in white or rose gold (I should move it now and notice that it’s a restricted release of 10 pieces in each metal, in spite of the fact that I don’t figure anybody would sensibly anticipate that FB should put out many these each day), and its strong, even straightforward development is intended to repeat that of the instance of the no. 6 ocean clock. (I ought to likewise make reference to that the gold for the cases adjusts to Chopard’s norms for morally sourced gold; Chopard joined the SBGA (Swiss Better Gold Association) in 2017 ).
So far, what we have is a clearly incredibly all around made, positively constructed wristwatch with a finely executed two-level lacquer dial, which clearly plans to be accepted both as a high-create object and, it could be said, a good old functional high-level chronometer watch too. In this sense, it helps me a piece to remember a portion of the watchmaking at A. Lange & Söhne, or of 19th and mid 20th-century chronometer-grade pocket watches, for example, the tourbillon observatory chronometers made by Vacheron during the 1930s. It is the point at which you turn the watch over that the impression is affirmed, and afterward some.
The development is the caliber FB-RE.FC, and like the dial and hands, it will promptly appear to Ferdinand Berthoud watchers both extremely natural and novel. One thing that is promptly and remarkably missing is a tourbillon, which has been a backbone of Ferdinand Berthoud watches since the brand’s first watch in 2015. The recognizable components are the conspicuous fountainhead barrel and upset fusée cone. The fountainhead barrel has a stopworks fitted to it – presently, a stopworks isn’t something you see in most current watches; it is a relic of a prior age when origins were made of carbon steel, instead of the innovative combinations which are these days universal . Such fountainheads didn’t have the generally level force bends of the origins of today, and as the heart loosened up towards the finish of its force hold, it would convey drastically less force, with an extremely harmful impact on rate stability. The stopworks is proposed, as the name suggests, to stop the watch before this sub-par some portion of its force bend is reached, by halting the origin barrel before it gets an opportunity to arrive at the finish of its force reserve.

The fusée and affix moreover are planned to improve the force conveyance bend of the fountainhead. The manner by which the fusée works will be natural to any individual who has at any point ridden a multispeed bike. To wind the watch, you don’t turn the origin barrel straightforwardly. All things considered, you turn the fusée cone, and in doing as such, you wind the chain off the heart barrel onto the cone. As the origin barrel turns, it winds the chain back onto itself, off the fusée. The cone is formed so particularly that as the heart debilitates towards the finish of its force hold, it has a continuously more prominent and more noteworthy mechanical bit of leeway. (The component clearly pre-dates its utilization in timekeepers; one of the soonest known utilizations for fusées was in windlasses for winding crossbows).
Generally, fusées are furnished with some kind of keeping up force system inside the cone – this is to guarantee the watch or check wherein the fusée is set will keep on running when the development is ended up (as the going train is driven by the fusée, winding the chain off the origin barrel onto the cone intrudes on force stream from the fountainhead to the fusée and train wheels, and without some kind of looking after force, the development would stop). Together, the stopworks and the fusèe and chain were normal for high-exactness watches and tickers for a large part of the historical backdrop of watchmaking.
While the tourbillon is missing in the type FB-RE.FC, there is another managing gadget in its place which is maybe stunningly better specifically lined up with the fusée and stopworks – a remontoire d’égalité. The remontoire is a component which has the very same broadly useful as the stopworks and the fusée, which is to guarantee the conveyance of an unvarying measure of force to the equilibrium over the whole force save of the mainspring. There are two essential sorts of remontoires – one is the gravity remontoire, which is intended for pendulum clocks driven by a falling weight and was concocted by the Swiss clockmaker Jost Burgi around 1595. The subsequent sort is the spring remontoire, which was concocted by John Harrison for his H2 ocean clock (and which he additionally utilized in the Longitude Prize-winning H4).
The fundamental thought behind the remontoire is genuinely direct. Rather than having the development driven straightforwardly by the fountainhead (or for this situation, driven straightforwardly by the fusée, and by implication by the heart), you have a second, more modest winding spring on one of the train wheels. This subsequent spring is intermittently ended up by the remontoire, which is controlled by the heart through the train wheels which go before it in the going train. Hypothetically, the remontoire spring can be on any of the going train wheels, albeit by and by, it’s frequently on the fourth or departure wheels. Essentially, the remontoire interferes with the immediate progression of force from the going train to the getaway wheel, and mediates an auxiliary force source, which is rewound at short enough spans by the remontoire instrument to give what is, in every practical sense, a steady and perpetual measure of force over the whole force reserve.

Here’s the way it works: In the type FB-RE.FC, the remontoire spring is on the break wheel, which has fifteen teeth. On the hub of the break wheel is a three-sided, manufactured ruby cam, looking like what is known as a Reuleaux triangle . The Reuleaux triangle is named for the German designer Franz Reuleaux, despite the fact that it was known – yet not under that name – significantly sooner; each edge of the triangle is a circular segment of a circle whose middle is on the contrary vertex of the triangle. The triangle has numerous potential uses – da Vinci utilized it as the reason for a guide projection – yet in mechanics, it is frequently used to make an interpretation of rotational movement into responding (to and fro) direct motion.

In the type FB-RE.FC, the triangle pivots as the getaway wheel turns; it pivots inside a fork which is moved to and fro as the triangle turns. As the fork moves to and fro, the remontoire anchor, to which the fork is appended, moves to and fro also. As the fork moves, it opens one of the three prongs of the remontoire stop wheel. In the picture, one prong of the stop wheel is laying on the upper bed of the remontoire anchor. At the point when the remontoire anchor moves far enough, the tip of the prong tumbles off the upper bed and the stop wheel pivots – clockwise, for this situation – until the tip of the following prong falls onto the lower bed, forestalling the prevent wheel from progressing again until the revolution of the ruby cam has moved the remontoire switch far back enough the other way for it to open thusly. The stop wheel is driven on its lower pinion by one of the going train wheels, and each time it snaps forward, it ends up the remontoire spring, holding it under enough strain to drive the getaway wheel, and in this manner, the switch and balance.
The Gafner-type remontoire in the Derek Pratt wristwatch.
The component is amazingly smart and exquisite – it was the creation of one Robert Gafner, a teacher during the mid-20th century at the watchmaking school in La Chaux-de-Fonds, and the Gafner framework is refered to as “earlier workmanship” in various resulting remontoire licenses . The framework was supported by the late Derek Pratt and a company which has as of late shaped to put his rendition of the Gafner framework into a wristwatch, as revealed by HODINKEE’s Nick Manousos in July , and the company has an incredible video, showing the activity of the remontoire in sluggish movement . You’ll see that while both the Pratt remontoire and the one in the type FB-RE.FC utilize the Reuleaux triangle, they each utilization an alternate arrangement for the stop wheel.
The equilibrium of the type FB-RE.FC vibrates at 2.5 Hz, and the departure wheel progresses 2½ teeth each second. The plan is set up with the goal that the remontoire anchor opens the stop wheel once for each 2½ getaway wheel teeth, which implies the stop wheel progresses once each second, making this a one-second remontoire. The way that the stop wheel progresses once each second implies that it tends to be utilized to drive a loser seconds hand, and in fact, the FB-RE.FC highlights a bum seconds. The main thrusts at the stop wheel are genuinely low, and to decrease the inertial burden on the instrument, the seconds hand is exceptionally slim and made of titanium as opposed to steel.
I discover the system totally awesome – it must be developed with extraordinary exactness, particularly in setting up and controlling the main impetus at the last going train haggle the remontoire spring; clearly, the ruby cam and different components should be made to totally numerically address shapes to get dependable bolting and opening. The way that the remontoire is very huge – similar to the equilibrium, with its overcoil balance spring and four inertial loads for fine acclimation to the rate – implies that the activity of the remontoire ought to be generally sensational and fulfilling to watch. One isn’t amazed to hear, after this, that the watch is guaranteed as a chronometer by the COSC, in spite of the fact that it is absolutely a long way from common for producers of high complications to request chronometer ratings.
I hate to raise finish now since it sounds very nearly an idea in retrospect, yet it was positively not a reconsideration to the people at Ferdinand Berthoud. Steel work is either grained or black cleaned, with sloped cleaned points and flanks, and an extremely undeniable degree of hand-completing is conveyed all through the whole development. Contacts like the agile, extremely three-dimensional rooster for the break wheel, remontoire spring, and remontoire stop wheel, with its black-cleaned cap, make the development as intriguing in its static components as its dynamic ones. The development plate itself is German silver, iced with a wire brush. The remontoire components are particularly a dining experience for the eye; all steel components have cleaned anglage –even the prongs of the remontoire stop wheel.
Assembly: putting the equilibrium cock.
The Ferdinand Berthoud Chronomètre FB 2RE is as genuinely lovely, mentally energizing, and sincerely including a watch as I have at any point seen. I locate the entire thought of making a watch which joins each of the three significant steady power instruments colossally captivating – having a fusée and chain, Maltese cross stopworks, and a remontoire all in a similar watch is so radiantly predictable in its over the top completeness as to be overwhelming, and the way that every one of the three are essentially outdated, from a commonsense viewpoint, just adds to the arrangement. As George Daniels put it, composing of the remontoire in Watchmaking, it is “very pointless, which only adds to its charm.”
Every now and again, a watch comes along that makes me wish I’d gone into money as opposed to distributing (gracious, individuals attempted to caution me), and this is one of those occasions. I will say, however, even at CHF 210,000, the FB 2RE.2 sort of feels like a deal, given how much blast you are getting for your horological buck. The entire venture is somewhat phenomenal, obviously – clearly, with Rolex making 1,000,000 watches a year appraised to ± 2 seconds out of each day greatest deviation in rate, putting a remontoire, fusée and chain, and a stopworks into a solitary wristwatch is an activity in showing make, not in propelling current modern mechanical horology. In any case, on the off chance that you’ve gotten this far, I trust you will concur that in case you’re willing and ready to spend such a cash on a wristwatch, it is difficult to consider one that coordinates the kin crafts of conventional horological mechanics and development plan and completing so particularly well as the Chronomètre FB 2RE.2 from Ferdinand Berthoud.
