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.

The perpetual calendar of the L.U.C Perpetual Chrono is recognisable by its large twin-aperture date display, complemented by indications of the day, the month and the leap or non-year nature of the 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 cheap replica watches in “Fairmined” white 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 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 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 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. 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 choice of fine materials runs right the way through to the strap of the L.U.C Perpetual Chrono, made of hand-sewn large-scaled black alligator leather.
