The return of the first stainless-steel Patek Philippe Perpetual Calendar Chronograph Ref. 1518 is reason enough to mark Phillips’ Decade One (2015–2025) thematic auction on your calendar – November 8 & 9. But this watch is not alone. Phillips will present it as part of an extraordinary “1518 Triptych” – three variants of the reference appearing together in the same auction: stainless steel, pink-on-pink, and yellow gold.
In this video, Aurel Bacs takes you through these three exceptional watches. It is the first time such a lineup has appeared at auction, and likely the last for a generation.
