Clé de Cartier
Cartier’s 2015 contemporary dress line — a soft-round case with a crown set into the case-band rather than the side (the "clé", or "key", that names the line). 40mm steel and precious-metal references with the in-house cal. 1847 MC. Discontinued in 2019; the line sits in the catalog as a closed reference an estate-market buyer still encounters.
