Extra-fort Roue à Colonnes Grande Date is a mechanical chronograph that perfectly combines aesthetical and mechanical elegance, in harmony with tradition and innovation. The chronograph’s functions are controlled by the column-wheel by means of a modified mechanical movement with automatic winding that operates in accordance with a new and exclusive process, namely a precise, accomplished mechanism that is visible through the sapphire glass caseback. Extra-fort Roue à Colonnes Grande Date reinterprets the elegant and harmonious lines of its predecessors and it is available in steel, in pink gold and in a special white gold version featuring a finely worked dial.
