Historical Context

Before the official introduction of the Extrafort line, Eberhard produced during the 1940s a series of chronographs now known among collectors as Pre-Extrafort. These models are characterized by substantial cases, technical design and reliable movements. The example presented here, with its 40 mm stepped stainless steel case and original dial featuring radium indexes and hands, represents one of the most attractive and sought-after configurations from this historical production.
