Chopard L.U.C Perpetual Chrono – Limited Edition

Chopard L_U_C Perpetual Chrono 7

This new L.U.C Perpetual Chrono from Chopard combines a hand-wound chronograph and a finely crafted perpetual calendar within an unprecedented L.U.C movement, Calibre 3.10-L. Issued in two series of 20 pieces in “Fairmined” 18-carat white gold and in “Fairmined” 18-carat rose gold, it is intended for watchmaking connoisseurs and devotees of exceptional objects.

Entirely developed and produced in the 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. The zero-reset system for the counters and the central sweep seconds hand is handled by progressive-contact hammers guaranteeing optimal 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 and whether or not it is a leap year, while the finishing touches are set by a day/night indication and an orbital moon-phase display. The latter guarantees graphic and accurate readings of the age of the moon, 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.

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). In parallel, each of these 20 watches in “Fairmined” gold – including both their movements and their cases – has successfully met the evaluation criteria of the Poinçon de Genève, which now encompass the watch in its entirety, providing an excellent guarantee of superlative craftsmanship and expertise.

The L.U.C Perpetual Chrono stems from high standards embodied in exceptional materials effectively underpinning its elegance and functionality.

The 45 mm case of the L.U.C Perpetual Chrono is entirely made of “Fairmined” 18-carat gold, sourced from Fairmined certified mining cooperatives in Columbia, Peru and Bolivia. The L.U.C Perpetual Chrono in white gold is the first L.U.C watch being produced out of 18-carat « Fairmined » white gold by Chopard.

The dial of the L.U.C Perpetual Chrono is coated with grey ruthenium. It is adorned with a hand-guilloché motif that creates subtle light effects radiating from the large twin-aperture date display.

The L.U.C Calibre 03.10-L is made of nickel silver, a naturally light grey alloy that ideally lends itself to surface treatment but cannot tolerate scratches. Any mistake made in executing the Côtes de Genève motif, circular-graining, satin-brushing and polishing operation omnipresent on the moment is irretrievable.

This movement thus calls for the most expert hands exercising their craft in the watchmaking workshops of Chopard Manufacture.

The strap of the L.U.C Perpetual Chrono is made of hand-sewn large-scaled vegetal tanned alligator leather. Given that a L.U.C watch will be admired from every angle, Chopard has also made the lining in chestnut brown small-scaled alligator leather.
