Historical significance
Patek Philippe Complications 40 mm Slate Ceramic sits within Patek Philippe's Complications line, introduced in 2021. It carries the house codes established since 1839 — ceramic case, slate grey dial and in-house manual-winding, hand-finished — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.

Brand history
Patek Philippe has spent more than 187 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Nautilus, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Antoine Norbert de Patek & Adrien Philippe established Patek Philippe in 1839, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Patek Philippe calibre produced today.
