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 Tank 39 mm Slate Platinum sits within Cartier's Tank line, introduced in 2009. It carries the house codes established since 1847 — platinum 950 case, slate grey dial and in-house automatic, superlative chronometer — and is one of the references collectors use to date the evolution of the collection.

Interesting facts

  • The movement's bridges are decorated even where they will never be seen once the watch is cased.
  • The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
  • Early production dials show a slightly different minute track, and collectors pay a premium for them.

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.
