The watch auction market has been rocked by seismic waves once again. Recently, at Phillips’ “Watches: Decade One” auction in Geneva, a rare Patek Philippe Ref. 1518 stainless steel perpetual calendar chronograph sold for a staggering 14.19 million Swiss Francs (approximately 17.8 million USD, or 545.68 million TWD). This astonishing hammer price makes it the most expensive Patek Philippe watch ever sold at a commercial auction, instantly making this event the focus of the year.

The renowned auctioneer Aurel Bacs, as usual, was the soul of the event. When this Ref. 1518, listed as Lot 23, appeared, the atmosphere in the room instantly became tense. Even before the introduction was finished, an Asian collector seated by the aisle shouted an opening bid of 8 million Swiss Francs, immediately igniting a bidding war. As this watch did not accept online bids, only five bidders participated (seemingly few, but each with remarkable financial depth), including three present in the room and two on the phone. Over ten minutes of fierce competition made the atmosphere almost palpable. Ultimately, a mysterious phone bidder secured it for 12 million Swiss Francs (approximately 14.19 million including commission), eliciting applause and gasps from the audience.

Interestingly, rumors had circulated the day before the auction regarding whether the watch had been refurbished. However, the result showed that market confidence was far stronger than the gossip, with collectors proving through their actual bids that the Ref. 1518’s rare value is unshakable.
This Ref. 1518 is already a legend in watchmaking history. Introduced in 1941, it is widely recognized as the world’s first serially produced perpetual calendar chronograph, serving as the technical cornerstone for Patek Philippe’s high-complication watches. The series was mostly crafted in yellow and rose gold, making the stainless steel version almost mythical. Only four examples are known to exist today. The one auctioned (case number 508’473, movement number 863’193) is the earliest of the four. According to brand archives, it was manufactured in 1943 and sold in Budapest on February 22, 1944.

For the market of the 1940s, pairing the most expensive complications with the most everyday material, stainless steel, was a counter-intuitive approach. It is precisely this sense of contradiction that makes the stainless steel Ref. 1518 the holy grail for collectors today. It combines functionality, history, and rarity—a classic dream for watch enthusiasts.
It is worth noting that this sale price once again demonstrates the resilience of the high-end vintage timepiece market. Even amidst current geopolitical tensions and unstable trade policies, these rare timepieces continue to attract top global collectors vying for ownership. Although the stainless steel Ref. 1518 did not break the vintage watch record set by the Rolex Daytona ‘Paul Newman’ Ref. 6239 in 2017 (over 17.7 million CHF), it has firmly reinforced the central position of mid-century stainless steel timepieces on the auction stage.

Since 2016, the price of the stainless steel Ref. 1518 has climbed from 11 million Swiss Francs to today’s 14.19 million. This remarkable increase in less than a decade is not just a continuation of collecting fervor but also symbolizes the market’s enduring desire for “classic and genuine” pieces.

Looking back at historical developments, Patek Philippe’s brilliance in the auction realm has never ceased. From the Henry Graves Jr. Supercomplication pocket watch sold for approximately 24 million USD in 2014, to the record-breaking charity auction of the Grandmaster Chime Ref. 6300A-010, each has become a significant chapter in watchmaking history. Now, the stainless steel Ref. 1518 perpetual calendar chronograph once again proves that when technology, history, and rarity converge perfectly, a watch transcends its function as a timekeeping instrument, becoming a top-tier collectible bearing the mark of its era.
