The Patek Philippe 1518 auction this fall is poised to become one of the most talked-about events in the luxury watch world. Known as one of the rarest and most coveted wristwatches ever produced, the stainless steel reference 1518 represents the pinnacle of watch collecting. With only four stainless steel versions ever made, this timepiece is a true unicorn in the horology world.

Why the Patek Philippe 1518 Auction Is Historic
Phillips, in collaboration with Bacs & Russo, is bringing this legendary watch back to the auction block. Previously sold in 2016 for around $13.6 million, the watch holds the record as the most expensive vintage Patek Philippe ever sold at auction.
The stainless steel reference 1518 is particularly significant because it combines technical innovation with historical importance:
- Perpetual Calendar & Chronograph: Among the first watches to feature both complications in a wristwatch.
- 1943 Introduction: Launched during World War II, highlighting the resilience of Patek Philippe’s craftsmanship.
- Exclusivity: Only 281 total 1518 watches exist, with just four in stainless steel.
As Aurel Bacs, senior consultant at Phillips, puts it, “Its return to auction marks a moment of rare opportunity for seasoned collectors and newcomers alike.”
