Meet Cartier Calibre de Cartier (ref. W7100056), 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. 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. Introduced 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.
