Published: 25 Aug 2025
The elusive, esteemed Patek ref. 1518, a perpetual calendar chronograph in a stainless steel case is making its triumphant return to the auction world, edging enthusiasts with anticipation.

For watch collectors, there are timepieces, and then there are grails. The Patek Philippe ref. 1518, a perpetual calendar chronograph clothed in a stainless steel case, is undeniably the latter. This revered artifact of horology, nearly a decade on from its previous record-breaking CHF 11 million sale, is tantalizingly ready for another auction block appearance. Known and appreciated as the first of its kind, the stainless steel-cased Patek ref. 1518 is one of just four known examples of such exquisiteness, a rarity that fans the flames of its desirability. This incredible wristwatch, first produced during the apex of the Second World War in 1943, is set to go under the hammer with an estimated price bracket of CHF 8 million to CHF 16 million. If reached, this staggering figure could represent the highest price paid at auction for any vintage wristwatch in recent memory, offering a new standard for ultra-rare and highly coveted collector timepieces. The Patek ref. 1518, in its sublime stainless steel incarnation, is nothing short of a paragon among horological circles. Initially produced in series from 1941, most of the total 281 known examples were made in yellow gold, with its rose gold counterparts deemed incredibly rare and valuable. The 1518’s unique stainless steel siblings, a mere four in existence, bring a sense of casual elegance that is anachronistic in its appeal, offering a tantalizing fusion of elite aesthetics and robust durability. In 2014, the steel 1518, was fondly christened as ’the holy grail’ by Ben Clymer, founder of Hodinkee, in the celebrated ‘Reference Points’ series. With its upcoming reappearance at auction, the timepiece’s profound allure continues to underscore its status as an end-game acquisition for many a collector. With every tick it makes, the Patek ref. 1518 reminds us of the enduring power and fascination of premium, classically adorned and crafted wristwatches.
