Tempus I Open-worked black dial

The first automatic Chronograph developed by Edouard Koehn in collaboration with an independent Manufacture of Haute Horlogerie mechanical movements based in La Chaux-de-Fonds, Switzerland, is a blend of tradition and modernity.

 The Tempus I Chronograph is a daily companion and becomes one with the wearer. Elegant on the wrist, it reliably punctuates events while awakening the senses. This Edouard Koehn watch is much more than refined aesthetics or complex mechanics, it carries passion and a host of feelings.

 The 245 components of the automatic Chronograph movement have been manufactured and assembled in the greatest Swiss watch making tradition, guaranteeing a very high-quality chronometric level.
