IWC Vintage Uhren Ersatzteile

Clémençon + Rieser

Clémençon + Rieser AG was founded in 1990 by Marcel Clémençon and Hans Rieser.

Marcel Clémençon and Hans Rieser were previously long-time employees of IWC and also completed their watchmaking apprenticeships at IWC Schaffhausen.

Hans Rieser was an apprentice at IWC in the mid-1950s and was later involved in the production of the famous vintage caliber 85.41. Hans Rieser passed this know-how on to Marcel Clémençon and later to Brian Unger.

Brian Unger, also an IWC-trained watchmaker, has been working in all areas at Clémençon+Rieser AG since 2018.

Personal, competent and trustworthy advice is our top priority.

We are a very motivated team and look forward to your visit here on the Fischerhäuserstrasse.
