Historical Context

Before the official introduction of the Extra Fort collection, Eberhard was already recognized as one of the leading manufacturers of professional chronographs. The so-called Pre-Extra Fort models from the 1940s are today among the most sought-after creations of the brand, appreciated for their exceptional build quality, mechanical reliability and unusually large case proportions for the period. This single-pusher example, featuring a 40 mm stepped stainless steel case, original black dial and caliber 16000 movement, is a remarkable witness to the golden age of Swiss chronograph production.
