Visually, it is a stirrup. Officially, it is named after a radiator grille (Calandre). Reference 6603 is a late 1990s re-issue of a design from the 1930s, supposedly modeled on a Bugatti front end. The definition lies in the asymmetry: a single hinged loop at 12 o’clock versus a standard bar at 6 o’clock. Often confused with the Jaeger-LeCoultre Etrier, this model runs on a quartz movement, prioritizing the case architecture over mechanical complexity.
Founded in Paris in 1847, Cartier approaches horology with the perspective of a master jeweler, prioritizing form, proportion, and aesthetic purity. The Maison was a crucial pioneer of the modern wristwatch, creating the purpose-built Santos-Dumont in 1904 for aviator Alberto Santos-Dumont and later the iconic Tank in 1917, whose "brancards" seamlessly integrated the case and lugs into a singular design.
While historically collaborating with ebauche movement suppliers, Cartier has since invested significantly in its own manufacture capabilities in Switzerland, developing a suite of in-house calibres. The brand's enduring significance lies not in technical innovation, but in creating a portfolio of iconic case shapes that are foundational to watchmaking itself.
