For the first time in its history, L'Heure du Diamant collection has a complication at the heart of one of its timepieces. Measuring just 20.40 mm by 4.60 mm, the 169 components composing the new self-winding Chopard Calibre 09.02-C enable it to fit neatly into a small ladies' watch case. An aventurine disc serves to display the moon's trajectory with remarkable precision. Calibrated by the Manufacture's finest watchmaking artisans, this display is endowed with astronomical precision: with a time difference of just 57.2 seconds between two lunar cycles, it will take 122 years for it to show a one-day discrepancy with the path of the actual moon. Only then will it need to be adjusted.
