Roman Numerals Signature
A standout feature of Cartier watches is their use of bold, black Roman numerals set against white or silver backgrounds. This design choice enhances legibility and contributes to the watch’s iconic and recognizable aesthetic.
The Signature Blue Cabochon
A hallmark of Cartier’s design is the elegant blue hands, complemented by the signature blue ‘cabochon’—a polished gemstone capping the watch’s winding mechanism.

Case Back Clarity
Upon examining the case back of a Cartier watch, the printing should be crisp and purposeful, fully identifying the watch with clarity and precision.
Serial Number and Case Reference
Authentic Cartier watches typically feature two key numbers: a unique serial number, commonly comprising six numbers and two letters, and a 4-digit case reference that indicates the watch’s model, reflecting its movement, shape, size, and design.
