The opening session of Phillips' Geneva Watch Auction: XXIV turned into a sustained rebuke of the printed catalogue, closing at CHF 48,712,850 after a run of lots that left their estimates far behind. The session at the Hotel President Wilson in Geneva on Saturday 7 November was led by independent watchmaking, with collectors paying multiples of the published ranges for the rarest pieces on offer.

The loudest result belonged to an F.P. Journe Vagabondage III in platinum set with baguette-cut diamonds, the first of ten examples made. Catalogued at CHF 350,000 to 700,000, it hammered at CHF 4.1 million and reached CHF 5,057,000 with fees, more than seven times the top estimate. The appeal was completeness: the watch, numbered one of ten and sold with its 2019 certificate and full set, closes the trilogy for collectors who already own the first two pieces. Another Journe, the Chronometre a Resonance "Regence", went further in absolute terms, hammering at CHF 7.1 million for CHF 8,680,500 with fees, the day's highest price, against an estimate described only as in excess of CHF 1 million.

The sale's biggest estimate fared no better. A stainless-steel Patek Philippe reference 1436 split-seconds chronograph from 1945, one of only two known in steel, carried a CHF 2 million to 4 million estimate and sold for CHF 6,267,000. The same watch made CHF 3,301,000 at Phillips in November 2015, so its price has nearly doubled in eleven years. A platinum Philippe Dufour Simplicity from 2004, estimated at CHF 350,000 to 700,000, reached CHF 1,968,500, while a black-dial Rolex Daytona "John Player Special" from about 1969 made CHF 1,905,000 against a top estimate of CHF 1.6 million.

The pattern raises a question for the houses' next catalogues: whether printed ranges will creep toward the room, or whether the market for the scarcest independent pieces has simply learned to price them faster than any auction house can publish. Session II, on Sunday, was set to offer the first clue.
