What does the Cartier Modern Signature look like?
Contemporary Cartier pieces carry a standardized 'Cartier' signature, metal purity stamp, serial number, and country of manufacture. Marks are laser-engraved on most production from the 1990s forward, replacing the earlier hand-struck punches. A reference number tied to the model permits archive verification through Cartier's client services.
Where is the mark located?
Usually struck on the inside shank or clasp interior.
About Cartier
Founded in Paris in 1847, Cartier maintains a precise system of maker's marks, serial numbers, and country-of-origin punches. Marks vary by workshop (Paris, London, New York) and by era, and are often paired with French assay marks (eagle head for gold, owl for imported pieces) and a unique serial number.
