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, 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 C both involving indications at 3 and 9 o'clock C 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.
