Since 1940, the year when the first model was presented, Extra-fort has known a particular fortune: over the years, it has been interpreted by the Maison in numerous versions and is one of Eberhard & Co.'s most popular and enduring collections. Today, Extra-fort in the vitré version is presented with all-new dial proposals. Featuring a steel case with a diameter of 39 mm, this timepiece preserves the unique charm of the "classic" Extra-fort chronograph, with its refined design and elegant Dauphine-type hands. The dial displays a sophisticated interplay of concentric patterns, alternating between the frappé execution with vertical lines and the azurée finish of the hour band, which is also found on the two counters.
