Chopard - L.U.C Lunar Big Date

Chopard – L.U.C Lunar Big Date

The silver-conditioned dial of the Chopard  L.U.C Lunar Big Date has some distinctive peculiarities which makes it truly recognizable: an original perspective on the moon stages showing both Northern and Southern sides of the equator, a large date display with two apertures at 12 o’clock, the small seconds indication somewhere in the range of 4 and 5 o’clock, the pointer-molded hands stressing the possibility of precision, and large applied Roman numerals.

The moon stage complication of this development is exact to such an extent that the difference between the actual lunar cycle and its indication is just one day each 122 years. To accurately reproduce the interval between two identical moon phases – known as a synodical revolution and equivalent to 29 days, 12 hours, 44 minutes and 2.8 seconds – the wheel which drives the moon-bearing plate comprises 135 teeth.

The 42 mm case, in polished white gold except for the glossy silk brushed case-band, houses the COSC-certified self-winding L.U.C Caliber 96.20-L. The development, visible through the presentation case-back, features two stacked co-axial barrels ensuring a 65-hour power hold to the balance oscillating at a pace of 28,800 vibrations for every hour. 

The Chopard L.U.C Lunar Big Date (ref. 161969-1001) is fitted with a hand-sewn black alligator leather tie secured by a white gold folding clasp and has a list price of Euro 24,490.
