Designer
In-house design studio
The reference was drawn by the manufacture's internal design office, where case, dial and movement architects work alongside the watchmakers rather than as an outside commission.
Historical significance
Patek Philippe Calatrava 36 mm Green Carbon sits within Patek Philippe's Calatrava line, introduced in 2006. It carries the house codes established since 1839 — carbon tpt case, green sunburst dial and in-house automatic micro-rotor — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
- The movement's bridges are decorated even where they will never be seen once the watch is cased.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.

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.
