In watchmaking, the association of the perpetual calendar with the hand-wound chronograph has always been considered one of the highest expressions of mastery. Chopard already provided this interpretation five years ago with the L.U.C Perpetual Chrono, powered by the L.U.C 03.10-L calibre. Now this multi-complicated timepiece, which bears both the Cosc chronometer certification and the Geneva Hallmark, is offered in a new version, with a grade 5 titanium case, alongside those in gold and platinum. The aforementioned movement (visible from the caseback side) combines perpetual calendar functions (with moon phases) with a flyback chronograph with column wheel and vertical coupling. With a power reserve of around 60 hours, this IWC-manufactured calibre has a diameter of 33 mm by 8.32 in thickness; its balance oscillates at a frequency of 28,800 vibrations per hour and the total number of its components is 452. The solid gold dial, black rhodium-coloured and hand-guilloché-engraved (with rays centred on the calendar), has a blued silvered flange with red and black decalised elements. Water resistance is guaranteed up to 3 atmospheres of pressure.
