Chopard: L.U.C. Perpetual Chrono

Chopard presents the new L.U.C Perpetual Chrono a masterpiece that combines two time frames; the longer scale of a calendar that provide its indications for centuries, and the shorter one for specific timing operations.

The L.U.C Perpetual Chrono comes with a 45 mm platinum case, vertically satin-brushed on the sides and polished on the bezel as well as the lugs, thereby creating a textured finish that gives it even greater visual depth. 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.

Entirely developed and produced in-house, the 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. 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, while optimising its legibility.

The L.U.C Perpetual Chrono is a limited edition of only 20 pieces and is certified by the the Swiss Official Chronometer Testing Institute “COSC” and the by the Poinçon de Genève.
