In-Depth: Patek Philippe Ref. 1518 in Stainless Steel | SJX Watches
The Patek Philippe Ref. 1518 in stainless steel is set to be a highlight at Phillips’ upcoming auction, boasting extreme rarity with only four known examples. As the first serially-produced perpetual calendar-chronograph wristwatch, it combines historical significance with a compact and understated design, measuring just 35 mm in diameter. Despite its inconspicuous appearance, the watch holds immense value, having once sold for almost $11 million. The appeal of the steel version lies not only in its craftsmanship and lineage but also in its paradoxical nature of being both ordinary and extraordinarily desirable. Each of the four known steel Ref. 1518s differs subtly in case design, with the auction example being the first of its series, made by Georges Croisier. The movement and dial maintain a high standard of craftsmanship typical of Patek Philippe, showcasing intricate details such as champlevé enamel markings and beautifully finished hands. Originally priced lower than its gold counterpart, the steel version is now estimated to exceed CHF 8 million, reflecting its status as a trophy watch in the world of horology. The upcoming auction on November 8, 2025, in Geneva is poised to see significant interest as collectors vie for this extraordinary timepiece.
