The L.U.C Haute Horlogerie collection has been enriched with a new technical prodigy, as this L.U.C Full Strike model adds a tourbillon with a sapphire bridge to the monobloc sapphire minute repeater inherent to the L.U.C Full Strike series.
This 42.5 mm timepiece in ethical 18-carat rose gold is equipped with the new chronometer-certified L.U.C 08.02-L movement. The extremely accomplished level of finishing, both on the movement and the case, has earned it the Poinçon de Genève quality hallmark.
Its dial, in ruthenium grey-coloured hand-guilloché rose gold, opens to reveal the two complications that make this 20-piece limited edition so sophisticated. Endorsed by virtuoso brothers Renaud and Gautier Capuçon, its acoustic richness achieves an exceptional level of quality, while perfect homogeneity makes it an unparalleled timepiece combining a stunning conceptual challenge with supremely accomplished execution
To celebrate the 25th anniversary of its creation, the L.U.C collection is welcoming a new flagship. The L.U.C Full Strike Tourbillon model takes its place among the most sophisticated and most innovative Grand Complication watches ever created to date. It follows in the footsteps of Chopard’s L.U.C Full Strike minute repeater timepieces, of which the first ethical rose gold edition was awarded the “Aiguille d’Or” best-in-show award at the 2017 Grand Prix d’Horlogerie de Genève. These timepieces feature a unique Chopard-patented system in which the gongs and sapphire crystal form a single entity, which resonates in its entirety to produce the chim
At 42.5 mm in diameter and 12.58 mm thick, the L.U.C Full Strike Tourbillon is distinguished by well-balanced proportions contributing to the characteristic elegance of the L.U.C collection. With its interplay of grey and gold colours between the case and strap, dial and hands, as well as between the movement’s steel and nickel silver components, this watch flaunts its aesthetic perfection at every level
For the first time in the history of the Full Strike, the L.U.C Full Strike Tourbillon model has an almost entirely solid dial. Instead of broadly revealing the watch’s internal mechanisms, it reserves its openings for the two horological complications that make this piece so special. The first cut-out between 9 and 11 o’clock, highlights the two mirror-polished steel hammers whose striking generates the chime. The other, at 6 o’clock, reveals the tourbillon of the L.U.C 08.02-L calibre. Thanks to a cross-through sapphire crystal tourbillon bridge, nothing obscures the view of the spiral-shaped carriage bridge. The final touch, made possible by the use of sapphire with its multiple properties, lies in the four rounded notches. This L.U.C signature tourbillon bridge is derived from a design by the founder of the Maison, Louis-Ulysse Chopard.
Chopard Manufacture watchmakers have placed the tourbillon of the L.U.C 08.02-L calibre at 6 o’clock, beneath the seconds hand. Its high-quality steel carriage picks up the distinctive spiral design – a signature of L.U.C tourbillons. This regulator further enhances the precision of the movement, a subject to which Chopard’s Co-President, Karl-Friedrich Scheufele, takes a resolutely uncompromising approach. It combats the adverse effects of gravity on the balance-spring and escapement by placing them in a variety of spatial positions. The tourbillon placed on the Chopard Manufacture minute repeater mechanism thereby contributes to the extreme precision of L.U.C Calibre 08.02-L as well as to the obtention of chronometer certification from the Official Swiss Chronometer Testing Institute.
The L.U.C Full Strike Tourbillon is not a mere modification of the L.U.C Full Strike. Moving from a calibre comprising 533 components to one with 568 is not an addition, but a revolution. The decision to include a tourbillon regulator required a complete development process that involved rethinking interactions and layouts. With such a delicate complication subject to as many parameters as the minute repeater, the Chopard Manufacture workshops had to ensure that this tourbillon would not in any way modify the acoustic qualities of the chime. This equilibrium is preserved by the sapphire gongs that are all-of-a-piece with the watch glass, which acts as a resonator. Moreover, the fact that the minute repeater has its own barrel naturally eliminates any energy-related interference, while the presence of the tourbillon does not alter the striking reserve
L.U.C Calibre 08.02-L inherits the unprecedented advances featured in the L.U.C 08.01-L: the first minute repeater movement introduced by Chopard Manufacture in 2016. In addition to its resonant structure, whose role is taken on by the sapphire crystal, several innovative technical systems have been added. It also benefits from the innovations introduced in L.U.C Calibre 02.01-L in 2003. A total of seven are the subject of patents. In a minute repeater mechanism, the energy used by the strikework is provided each time the arming lever is activated. Here, the energy comes from a separate, dedicated barrel wound directly by the crown.
It enables the L.U.C Full Strike Tourbillon to chime a maximum of 12 times the most complex and energy-intensive time: namely 12 hours and 59 minutes. This exceptional power reserve is due to several factors. Benefiting from a patented clutch-lever device, it ensures that the strikework gear train is blocked to avoid losing power reserve during the information capture that controls the minute repeater.
Keen to preserve the user-friendliness of the minute repeater and to make its operation as secure as possible, Chopard Manufacture has introduced a number of innovative systems. Thus, if the barrel no longer has sufficient force to power the minute repeater, a safety mechanism blocks its release. In addition, Chopard has filed a patent for a new strikework-activation device. As soon as it is activated, the pusher is disengaged, thereby making it impossible to disturb the running of the minute repeater or to damage it
The Chopard L.U.C Full Strike Tourbillon is actually part of a Trinity Trio made of three watches including the Full Strike Sapphire and the Full Strike One …all relying on the Sapphire technology to produce the best resonating sound for the strikes.
The L.U.C Full Strike Sapphire timepiece is the first minute repeater watch whose case is made entirely of corundum crystal, better known as sapphire. By merging container and content, musical expression and transparency, Chopard has created a veritable horological musical instrument. Thanks to the homogeneity of the material – which is present throughout the sound propagation chain – this five-piece limited series gets the very best from sapphire.
Above and beyond its aesthetic prowess, the choice of lab-created sapphire is justified by its technical properties: derived from synthetic corundum, this material is one of the most resistant to scratches and has an estimated hardness of nine on the Mohs scale, almost as hard as diamond. Moreover, although producing a sapphire case entails considerable machining difficulties, it has the advantage of remaining unalterable over time.
