Here’s Chopard’s addition to ‘Only Watch 2011‘.
And here’s the official word:
[Press Release] A unique piece designed for Only Watch 2011: the Only Watch L.U.C Engine One Tourbillon is powered by an exceptional “motor”, proprietary L.U.C Calibre 1TRM. Machined like an engine and mounted on silent-blocks, this mechanical hand-wound tourbillon movement was designed, developed and produced at Chopard Manufacture.
In 2010, Chopard introduced the L.U.C Engine One Tourbillon model to celebrate Chopard’s 150th anniversary. This year, Chopard releases a special black and yellow toned version of the now famous automobile spirited timepiece for the annual Only Watch Charity Auction to benefit Duchenne muscular dystrophy research.
Honoring automobile traditions
From its strong lines to the most subtle details, everything about this powerful timepiece honors automobile traditions. The L.U.C Engine One Tourbillon model houses a proprietary mechanical hand-wound tourbillon movement, L.U.C Calibre 1TRM. Like a car engine, this movement is mounted on silent blocks – that absorb shocks – and held by three lever arms inserted into the case middle. Designed, developed and produced by Chopard Manufacture, this L.U.C Calibre 1TRM beats at a cadence of 28,800 vibrations per hour and boasts a 60-hour power reserve. Chronometer-certified by the COSC, a sure token of reliability and precision, this tourbillon movement drives the hours, minutes, seconds, and power reserve displays.
The reamed engine block bears the Chopard signature, while a circular segment fixed directly on the movement at 12 o’clock carries the power-reserve display which is positioned opposite the tourbillon bridge at 6 o’clock: a design that is a first for Chopard.
A DLC titanium case
Representing a magnificent mechanical feat of engineering, the L.U.C Engine One Tourbillon Only Watch is distinguished not only by its high-end motorisation, but also by its bodywork that endows it with an inimitably sophisticated style. The DLC titanium case is water resistant to 50 meters and features alternating polished and matte finishes; it also carries slightly curved lugs screwed onto the case that enhance the overall dynamic effect. Streamlined like car wings, these lugs ensure excellent wearer comfort and a perfect fit on the wrist for the opulent 35.4 x 44.4 mm case, which is engraved with “Only Watch 2011” on the side.
The dial is also inspired by the automobile world and plays on the theme of transparency. Beneath the glare resistant sapphire crystal are engraved yellow-tinted hour markers and the new Arabic numerals characteristic of the L.U.C collection. The hand-sewn black alligator leather strap, setting the perfect finishing touch to this model, is enhanced by four reinforced inserts evoking the seats of classic racing cars.
