The CHOPARD L.U.C. Lunar Big Date
If you take a close look at the Chopard ‘s LUC collection (that pays homage to the maison’s founder Louis-Ulysse ) you will easily realize that the manufacturer is obsessed with moon phase complications for it is widely adopted by Chopard on most of its high-end wristwatches. The latest entry is the Chopard LUC Lunar Big Date with which the maison has debuted a couple of days ago.
The Chopard LUC Lunar Big Date is the second edition of a model that first appeared in 2009 and after five years, during which Chopard has worked to upgrade its technical feats even further: the maison claims the indication is so precise that the gap between the rated value and the real lunar cycle amounts to just one day in 122 years.
The moon phases are displayed, for both Northern and Southern hemispheres, through an opening cut on a disc, placed at 8, where they placed the Big Dipper constellation along with the Southern Cross , the smallest among the 88 known constellations.
The Chopard LUC Lunar Big Date features a 42mm wide white gold case, big date indication at 12, silver-toned sunburst satin-brushed dial with roman numerals, dauphine like hour, minute and second hands; it is powered by an in-house movement with two barrels that ensures a total 65 hours of power reserve and whose balance wheel vibrates at 4Hz.
The movement, which is COSC certified, is visible through the transparent case-back where, among other things, stands out the gold micro-rotor, a technical solution widely used on mechanical automatic high-end calibers in order to reduce their thickness.
