Dear Sir or Madam,

For many years now we have been working closely with renowned auction house Dr. Crott whenever historical timekeepers by A. Lange & Söhne are concerned. Its experts have been specializing on high value pocket watches since 1975 and their special interest lies in the brand A. Lange & Söhne. Most notably Stefan Muser is always a most competent contact and for many years now we have been referring all owners of our timepieces to Auctioneers Dr. Crott whenever information on any of the historical Lange watches is needed.

With kind regards,
