Introducing Cartier Calibre de Cartier (ref. W7100042), an elegant watch engineered for daily versatility and long-term reliability. From profile to crystal, the architecture convinces: measuring 42 mm in diameter, with a thickness of 10 mm, defined by a round silhouette, paired with a rotating, 0-60 (dive) bezel. The caseback is open, and the crystal is sapphire, delivering water resistance to 10000 meters. Up close, the dial rewards inspection: a silver tone with guilloche finish, framed by mixed hour markers, and sword hands. Inside, precision takes center stage: the 1904-CH MC caliber. Initial production year: 2012. Designed for real-world wear, the watch transitions smoothly from tailored looks to casual settings. Manufacturing tolerances and surface treatment highlight consistent quality control. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
