Designer
Louis Cartier
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
Cartier Santos 36 mm Silvered 18k sits within Cartier's Santos line, introduced in 1986. It carries the house codes established since 1847 — 18k white gold case, silvered opaline dial and in-house automatic chronograph — 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
Cartier has spent more than 179 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Santos, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Louis-François Cartier established Cartier in 1847, working from France at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Cartier calibre produced today.
