The Grand Prix de Monaco Historique Chrono bears all the hallmarks of a true classic racing "thoroughbred". The case adopts a new ergonomic shape with tauter, more dynamic lines. Its diameter has been broadened to 44.5 mm and the dial has been entirely redesigned with grooves similar to those marking the end of race-track turns. The hour-marker ring is designed all of one piece like a brake disc and punctuated by arrow-shaped luminova hour-markers that are part of the new signature features on Chopard Classic Racing models.
