About Horological Consultancy

Dr. Helmut Crott

As an expert in the field of evaluating exceptional timepieces, I have been directly involved in providing valuations, consulting and advice on horological masterpieces of all genres for more than half a century. These years of experience gained by actually handling, examining, analyzing and studying rare and valuable timepieces first hand have allowed me to gain invaluable insight that could not have been acquired any other way.

During this period I also created the world’s largest, most comprehensive and detailed Patek Philippe database™ and amassed a reference library filled with rare and unusual source materials on horology from its earliest period to the present. These are just some of the important tools that assist me in providing clients with the highest quality of services when they wish to buy and sell valuable timepieces, to develop a high-level private collection or to create a watch portfolio as an investment.
