PENDULUM BOUTIQUES

In 1891, Edouard Koehn (1839 to 1908) reinvented himself as an independent watchmaker specializing in complications. The chronographs, repeaters and complications mechanisms crafted by the master watchmaker were on par with those produced by esteemed brands of that era, a fitting testament to three decades of watchmaking experience Edouard Koehn gained at a reputable Swiss watch Manufacture.
