Facts & Figures 2025

For us – and we believe also for many of our clients – 2025 was a highly successful auction year. Demand for art, exceptional objects, as well as rare jewellery and wristwatches, was remarkably strong. Our multi-day auction series in March, June, September and November achieved excellent results. Of the approximately 9000 objects offered, 80% found a new owner. Expectations reflected in the catalogue estimates were frequently exceeded: overall, hammer prices stood approximately 60% above the lower estimates.

Our auctions attracted considerable international attention. Around half of all objects were sold to buyers from the European Union, the Far East and China, South America and the United States. Our 20 specialised departments draw on many years of experience, in-depth expertise and an extensive international network.
