The new Vacheron Constantin Patrimony moon phase and retrograde date is an invitation to raise our gaze skywards. This new timepiece, with its pure lines typical of the Patrimony collection, features a dial on which the cycle and age of the moon are reproduced on a display that will require no corrections for 122 years. Vacheron Constantin is combining this elegant complication with a retrograde date indication, graduated from 1 to 31 across the upper dial arc. Equipped with a Manufacture movement, the Patrimony moon phase and retrograde date is certified by the prestigious Hallmark of Geneva, a sure token of excellence.
