A LOOK BACK AT THE SUMMER AUCTIONS
Koller’s June auctions were spectacularly successful, with seven lots breaking the million mark, more than 50 lots selling for between CHF 100 000 and CHF 1 million, and over 85% of all lots sold. There was auction fever in the saleroom during the entire auction week – some lots had over thirty telephone bidders competing, along with saleroom and online bidders. Two world records were set in the Watches auction, including the CHF 2.4 million achieved for a Rolex ‘Paul Newman’ gold Daytona.

Highest auction price in the DACH region, first half of 2026
Seven lots passed the million mark, more than 50 sold for between CHF 100 000 and CHF 1 million, and over 85% of all lots sold.
Two works by Ferdinand Holder sold in the seven figures. ‘Sunset on Lake Geneva from Caux’ was the subject of a fierce bidding battle which ended at CHF 7 million, among the top prices ever achieved for Holder at auction. ‘The Jungfrau massif from Mürren’, also from Hodler’s mature period, sold for CHF 1.8 million.
Robert Rauschenberg’s large-format work ‘Crosstown [Anagram (A Pun)]’ from 1997 sold for more than four times its lower estimate at CHF 450 000, and a 1952 landscape by Nicolas de Staël fetched CHF 375 000. Homage to the Square (White Enclave) by Josef Albers tripled its lower estimate at CHF 350 000.
The Watches sale was once again a ‘White Glove’ auction, with every lot finding a buyer. Besides the CHF 2.4 million auction record set by the Rolex ‘Paul Newman’ 18K gold Daytona watch, a Rolex ‘Kew A’ chronometer from the 1950s also set an auction record at CHF 287 500. The Jewellery auction was also a resounding success, with a by-lot sales rate of over 90%, and hammer prices totalling 1 ½ times the lower estimates.
