Cartier Calibre de Cartier Steel Silver Dial 42mm Ref. W7100015 embodies Cartier’s transition into modern watchmaking with its first widely released in-house movement, the selfwinding calibre 1904-PS MC. Housed in a robust 42mm stainless steel case with a matching bracelet and deployment clasp, this model highlights a bold round design balanced by signature Roman numerals and sword-shaped blued-steel hands on a silver dial. A scratch-resistant sapphire crystal ensures clear visibility, while the 48-hour power reserve supports uninterrupted performance. With water resistance to 30 meters and a practical date display, this watch blends daily reliability with iconic Cartier aesthetics, marking a significant chapter in the brand’s technical evolution.
