As the Grand Prix D’Horlogerie de Genève (GPHG) grants service is quick drawing nearer, the competition is warming up between designated brands. One of the classifications with really fascinating competitors with regards to the Chronometry Category. Among the pre-chosen watches is the new Ferdinand Berthoud Chronomètre FB 2RE. Named after a distinguished 18th-century watchmaker, the brand was restored in 2015 by Karl Friedrich Scheufele. Inside only a couple years, Ferdinand Berthoud has figured out how to snatch two prizes at the GPHG, including the lofty Aiguille d’Or in 2016! For 2020, as the brand is competing in the chronometry class, Ferdinand Berthoud has quite recently delivered the chronometric exhibitions of one of its Chronomètre FB 2RE.
The Chronomètre FB 2RE is the brand’s first current, round-formed watch and was enlivened by Ferdinand Berthoud’s marine chronometers. The 44mm case gets the state of a round chamber and houses an amazing Grand Feu veneer dial with Roman numerals. From the start, the model seems, by all accounts, to be a period just wristwatch however turning the watch over, the presentation caseback permits you to find a wonderful and amazing development. The type FB-RE.FC combines various components to manage the main impetus conveyed to the oscillator, a fusée-and-chain fitted with a Maltese cross stop-work and a remontoir d’égalité.

Keen to exhibit or affirm the potential chronometric execution of the model, Chronométrie Ferdinand Berthoud submitted one of its FB 2RE watches to explicit tests. Much the same as any piece qualifying as a ‘Chronometer’, its development went through estimations in lab conditions by the Official Swiss Chronometer Testing Institute (Contrôle Officiel Suisse des Chronomètres, COSC) for 15 days. Also, when the development was housed for its situation, the Fleuritest test system tried the watch’s 50-hour power hold by reproducing genuine developments on the wrist.
And the outcomes are fairly amazing, in reality. Over the whole span of the force hold, the readings taken show inconsistencies of under 0.5 seconds on normal from the benchmark clock! As a comparison, the measures (or all the more definitely one of the rules) for chronometer accreditation is a normal day by day rate variety between – 4 to +6 seconds, which means as long as 10 seconds out of each day. Furthermore, because of the consistent power instruments, the normal plentifulness estimated for the Berthoud FB 2RE chronometer tried shows a decreased variety all through the running time with a standard deviation of simply 2°/a normal sufficiency 301° (for a standard mechanical development, the motions of the equilibrium wheel are influenced by the varieties of its main thrust in a substantially more critical manner, explicitly towards the finish of the force reserve).
