Introducing Cartier Calibre de Cartier (ref. WSCA0006), a refined timepiece that blends thoughtful design with reliable performance. A study in proportion and durability: crafted in stainless steel and measuring 42 mm in diameter, with a thickness of 11 mm, defined by a round silhouette, paired with a rotating, 0-60 (dive) bezel, protected by adlc coating. The caseback is closed, and the crystal is sapphire, delivering water resistance to 30000 meters. The dial composition is deliberate and legible: a black tone with matte finish, framed by mixed hour markers, and sword hands. Beneath the caseback lies dependable performance: the 1904-PS MC caliber. First released in 2013. Comfort and balance define the wearing experience, making it an easy daily companion. Subtle transitions between textures elevate the overall impression. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
