Welke timepiece zou beter geschikt zijn om de 195ste verjaardag van Bovet te vieren dan een Big Date Tourbillon? Naast zijn subtiele historische toespelingen vertegenwoordigt deze Virtuoso VIII de essentie van de Fleurier Grandes Complications collectie, zoals gedefinieerd door Pascal Raffy zelf. Dus, terwijl de Dimier Collection is ontworpen om de laatste ontwikkelingen en innovaties in ontwikkeling en technologie te presenteren, is de Fleurier Grandes Complications Collection toegewijd aan het voortdurend verheffen van traditionele ambachtelijke horloges naar nieuwe hoogten.
De Virtuoso VIII is echter de eerste keer in de Fleurier-collectie om een scherpe kristalopening weer te geven langs de 12-uur-achtige as, zoals het innovatieve geval van de Récital 18 Shooting Star® die in 2016 werd gepresenteerd en die van dit Récital 20 Astérium® van het jaar. Dit echt innovatieve concept creëert nieuwe perspectieven voor kaliberarchitectuur, ook voor de decoratie en weergave van functies. De beweging van deze nieuwe ambassadeur voor de collectie beschikt ook over een aantal belangrijke innovaties, evenals drie van de patenten die door Braveheart® Tourbillon werden gepresteerd, die oorspronkelijk in 2015 werd gepresenteerd. Maar vooral, de Virtuoso VIII is de ultieme uitdrukking van De artisanale horloge traditie die sinds 1822 door Bovet is gehandhaafd.
Het nieuwe kaliber dat Virtuoso VIII machtigt, profiteert van alle kennis van de horlogemakers in Bovet. Uit het uitgebreide test blijkt dat deze laatste al een goed gestructureerde reputatie heeft verdiend voor zijn betrouwbaarheid en capaciteit om verschillende aanvullende mechanismen te runnen. De energie van het kaliber dat de Virtuoso VIII uitrustt wordt vrijgegeven door een enkel vat, dat meer dan tien dagen autonomie biedt, terwijl de oscillaties van het balanswiel bij 18.000 vph worden gehandhaafd. De baanbrekende structuur van de vliegende tourbillon heeft ook zijn waarde bewezen in termen van betrouwbaarheid en chronometrische prestaties. Maar voor de Virtuoso VIII, besloot Pascal Raffy zich te kiezen voor een architectuur die typisch is voor 19de-eeuwse horloges, met een volledige plaat en bruggen die in een reeks scrolls zijn uitgewerkt.
This patented double face flying tourbillon has already demonstrated its full chronometric potential. Its fixed point in the center of its axis together with the distribution either side of the escapement and balance-spring give it a balance that drastically reduces the lever-arm effect and friction at the pivot point. To further improve the performance of this tourbillon, a new regulating organ has been developed and produced by the brand’s artisans. The pace of the new caliber is set by a variable inertia balance wheel. Six collets driven into the felly of the balance wheel allow for dynamic setting of the utmost precision. The balance-spring has been specifically calculated for this caliber and balance wheel by the craftsmen at Bovet. It is fixed to the tourbillon bridge by a double-ended mobile balance-spring stud support in accordance with the finest chronometric practices. The hand-finished wheels, traditionally burnished pivots and teeth cut using traditional artisanal methods also improve the chronometric performance of this caliber.
In 1822, the Bovet brothers took the decorative watchmaking arts to their highest summits. Since 2001, Pascal Raffy has set out to perpetuate this heritage. The design and decoration of the caliber of the Virtuoso VIII are the ultimate expression of this.. The steel is chamfered and polished. The disk plates are sunk and chamfered. The two sides of the plate are also chiseled with an extremely delicate pattern that demanded the utmost skill from the Manufacture’s engravers to achieve a harmonious contrast with the sumptuous surface of the bridges, which are decorated with the emblematic Fleurisanne engraving. The chamfered and polished edges of the bridges artistically frame the Fleurisanne adornments and clearly define the two distinct decorations. The bridge ofthe tourbillon carriage, meanwhile, is in titanium to lighten the latter and eliminate any possible magnetic charge. These two elegant arms, which spread like wings above the flying tourbillon, were also rounded-off and polished in line with artisanal fine watchmaking traditions. All of these many operations were carried out by hand by the artisans in brand’s decoration workshops.
For their part, the dial-makers have showcased the decoration of the movement to perfection by creating two harmoniously arranged dials. The first indicates the power reserve while the second displays the hours, the minutes, and the magnificent big date aperture. In order to conceal only those mechanisms that would otherwise interfere with the timepiece’s legibility, the surface area of the dials has been reduced to a minimum while sumptuous, rounded-off and hand-polished attachments straddle the bridges before anchoring themselves solidly to the movement. Whether the dials feature lavish ivory or black lacquer or precious blue aventurine, the Arabic numerals and their graduations, as well as the shape of their hands, have been directly inspired by the historic pocket watches from the Bovet’s collections.
For the Virtuoso VIII, this core value primarily concerns its main additional function: the big date. This was designed in such a way that its mechanism occupies the smallest possible surface area while displaying as big a date as possible: two opposing constraints that have been masterfully resolved. It is hard to believe that the diameter of the dial overlooking the big date disks could result in such a sizeable display. The space between the unit disk and hours disk has been reduced to the strict minimum in order to further optimize legibility and enable the use of a single aperture without separating the tens from the units. And the watchmakers have not forgotten date correction either: the date can be quickly modified by simply pressing the crown, meaning that wearers of the Virtuoso VIII need not even remove it from their wrists. The tension of the rapid date corrector together with the emblematic positioning of the crown and bow of Fleurier cases at 12 o’clock neatly avoid any accidental date correction.
The seconds display was the subject of similar attentions. Designed with exceptional readability in mind, it makes use of an hour-marker screwed to the carriage wheel. The arrow of the hour-marker overlooks the surface of the ring dial that displays the sixty seconds.
