Review 2025

2 KOLLER INTERNATIONAL For us – and we believe also for many of our clients – 2025 was a highly suc- cessful auction year. Demand for art, exceptional objects, as well as rare jewellery and wristwatches, was re- markably strong. Our multi-day auc- tion series in March, June, September and November achieved excellent re- sults. Of the approximately 9000 objects of- fered, 80% found a new owner. Expec- tations reflected in the catalogue esti- FACTS & FIGURES 2025 ‘80%of all lots found a new owner.’ mates 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 inter- national network.
