The Extra-fort Roue à Colonnes Grande Date is a mechanical chronograph in which aesthetic refinement and mechanical sophistication are perfectly combined to create a skilful balance between tradition and innovation. The chronograph functions are «directed» and controlled by the column wheel via a mechanical automatic movement modified according to an exclusive system. A particularly refined precision mechanism, visible through the sapphire glass caseback. The Extra-fort Roue à Colonnes Grande Date reinterprets the elegant and harmonious lines of its predecessors and is available in steel and in 18 ct. pink.
