Since being the first calendar complication presented by Chopard Manufacture in 2005, the L.U.C Lunar One model has remained the only timepiece in its category equipped with a precision orbital moon-phase display featuring a rotating window. The mechanical self-winding L.U.C Calibre 96.13-L with perpetual calendar and astronomical moon-phase function – achieving a rare degree of accuracy guaranteeing a single day's difference in 122 years – powers two new timepieces whose profile has been revisited in line with the latest L.U.C aesthetic. Framed by a 40.5 mm-diameter case in ethical 18-carat gold, the hand-guilloché dial demonstrating artisanal expertise is distinguished by highly legible indications, while an ingenious interchangeable strap system offers a variety of styles. While the movement’s accuracy is chronometer-certified, the high-quality finishing of these two L.U.C Lunar One models has also earned them Poinçon de Genève recognition.
