1839 — 1908. Edouard Koehn, master watchmaker. A life devoted to the silent geometry of escapements and the integrity of fine mechanics.

The Founder
A master watchmaker whose name became a byword for the most demanding complications of his era.

Edouard Koehn began his career as clockmaker to the court of the Grand Duchy of Saxe-Weimar-Eisenach, born into an atmosphere of the highest horological standards.
He later joined Patek Philippe in Geneva, where his exacting eye for finishing and his architectural sense of movement design earned him a partnership in the Maison Patek, Philippe & Cie.
In 1891, he founded his own house. Among connoisseurs of haute horlogerie, the split-seconds chronograph — the most complicated of all chronographs — became the complication most closely associated with his name, a thread the Maison carries forward today.
Caliber EK CHR11
The caliber visible through the sapphire case back is exclusively developed by Concepto Watch Factory for Edouard Koehn — 282 components, 31 jewels, a 4 Hz frequency and a 48-hour reserve. The regulating organ is finished to chronometer “Top” grade and adjusted to five positions.

“The hand that finishes a movement leaves nothing of itself — only the proof that nothing was rushed.”
