Launched on the occasion of the Maison’s 125th anniversary, Extra-fort Roue à Colonnes Grande Date 125ème Anniversaire is an exclusive model produced in limited edition — 500 pieces for the steel version and 125 for the precious gold edition — to mark this important event, thus reaffirming the Brand’s ability to passionately and consistently pursue its calling for innovation, while preserving its personality and independence. The technical preciousness of Extra-fort Roue à Colonnes Grande Date 125ème Anniversaire resides in the column-wheel that controls the chronographic functions of the mechanical automatic movement, perfectly matching the aesthetic refinement of the model.
