Eberhard & Co. 20 Years of Chrono 4

In 2001, Eberhard & Co. launched Chrono 4, one of the most innovative chronographs ever produced by the Swiss watchmaking industry.

Boasting an original design and equipped with a patented movement, this unprecedented chronograph watch features four horizontally positioned counters. The genius behind this iconic creation was Palmiro Monti, who was the brand’s CEO at the time. The Swiss brand now celebrates 20th anniversary of this incomparable horological marvel by launching a new Chrono 4 series.

Celebrating the twenty years of success and innovation, the new Chrono 4 embodies all the technical expertise developed by Eberhard & Co. since its establishment, with a visual appeal in keeping with contemporary styling. The stainless case measures 42 mm in diameter. The finish is polished, as is the steel bezel featured on one of the two versions, the other having a ceramic bezel and a more sporty-looking tachymeter scale.

The new model is equipped with the Caliber EB.251, the same patented self-winding movement that has been powering all Chrono 4 watches since its introduction.

The wide selection of dials, all protected by sapphire glass cases with internal anti-reflective coating, features “Clous de Paris” processing in the central area and ‘azurée’ for the four counters, and ranges from an overall black, white or air-force grey appearance to contrast versions in black/white or silver/black.
