The new L.U.C Perpetual Chrono by Chopard Replica watch interprets the exclusivity of platinum combined with a hand-wound chronograph and a finely crafted perpetual calendar.
After a limited series in Fairmined gold launched in 2016, the L.U.C Perpetual Chrono appears in platinum this year. 950 platinum is a noble and completely stable metal featuring a dark and neutral shade of grey. The 45 mm case crafted from this rare material is vertically satin-brushed on the sides and polished on the bezel as well as the lugs.
The dial is in solid gold, adorned with a hand-guilloché motif. A high-precision galvanic treatment endows it with its deep blue shade, the colour chosen by Chopard for its platinum limited series.
The choice of noble materials extends right the way through to L.U.C calibre 03.10-L, which is made of nickel silver, a naturally light grey alloy that ideally lends itself to surface treatment but cannot tolerate scratches. Nickel silver is harder than brass, more resistant to oxidation and acquires a natural patina.
Entirely developed and produced in the Replica Chopard Haute Horlogerie workshops, L.U.C calibre 03.10-L is built around a column wheel that controls all chronograph operations including the flyback function. Zero-resetting is done by means of progressive-contact hammers, a guarantee of precision. It ensures smooth yet firm activation of the timing-related components via a vertical coupling clutch. This was the exceptional base mechanism chosen to house the perpetual calendar of the L.U.C Perpetual Chrono.
This calendar is recognisable by its large twin-aperture date display, complemented by indications of the day, the month and the cycle of standard and leap years. The finishing touches are set by a day/night indication and an orbital moon-phase display, with a mere one-day deviation in 122 years. Since the original configuration of this calendar uses the same areas as the chronograph – both involving indications at 3 and 9 o’clock – the architecture of the perpetual calendar had to be adjusted to offset the day/night indicator by a few millimetres. This arrangement determined the specific layout of the dial and its counters, while optimising its legibility.
The L.U.C Perpetual Chrono has earned double certification : the rating precision of its L.U.C Calibre 03.10-L has been certified by the Swiss Official Chronometer Testing Institute (COSC) while each of these platinum watches – meaning both movements and cases – has successfully met the evaluation criteria of the Poinçon de Genève.
