Eberhard & Co. Scientigraf Chrono

Reading Time: 2 minutes

A new timepiece enters the Eberhard & Co. catalogue: the Scientigraf Chrono. The watch is a chronograph version of the famous anti-magnetic Scientigraf model launched in 1961, whose technical and aesthetic characteristics are enhanced by the presence of two counters.

The chronograph, like the “time only” version, is distinguished by the presence of a “Faraday cage” contained in the case: a structure made of soft iron that absorbs the electromagnetic waves of devices that are now ubiquitous in everyday life, thus protecting the movement of the watch, whose precision characteristics are not affected.

From an aesthetic point of view, the Scientigraf Chrono retains its retro appeal: on the black dial, the two counters stand out (decorated with a refined azuré finish) and the triangle element, which appears in many details (such as the hour markers, proposed in ivory or orange, or the tips of the hour and counter hands). The 41 mm steel case, which contains the Faraday cage, alternates between polished and satin-brushed finishes, while the screw-locked case-back bears the original design of the model launched in 1961, with the logo and inscription recalling the anti-magnetic tests carried out at the time in the dedicated facility in La Chaux-de-Fonds.
