Extra-fort represents an important stage in the history of watchmaking. Born after the war,
became synonymous with a new era of watchmaking in the 1940s. Half a century later, this now famous Eberhard & Co. watch was reinterpreted and refined by the Swiss Maison itself.
The Extra-fort collection consists of an automatic mechanical movement and cases in steel, rose gold or 18 ct white gold. The special "Grande Date Réserve de Marche" models feature a transparent sapphire crystal case back to reveal the movement with its "Côtes de Genève" embellishments.
