The specialist for vintage watches

About us


For more than 40 years the name Auktionen Dr. H. Crott has stood for competence in timepieces. Founded 1975 in Aachen by the expert and collector Dr. Helmut Crott, the auction house rapidly established an international reputation as a reliable partner for watch and clock enthusiasts.

After many years of dedication to the business, Dr. Crott retired in 1993 and passed his successful and distinguished auction house on to Stefan Muser. To this day the company carries the name Dr. Crott, with whom we share a deep and trusting relationship and who still holds an intense interest in the development of the auction house.

Auktionen Dr. H. Crott moved to Mannheim (near Frankfurt/Main) in 1994, where the excellent infra­structure makes for easy access for the ever increasing international customer base.
