When it comes to fusing their distinct designs. The Maison is the expert, their subtle inclusion of various elements is explained through the Ronde Solo.The WSRN0021 borrows its dial layout from the Tank with its silver opaline dial as a clean canvas for the signature black Roman numerals and blued-steel sword hands.

Its bezel style is flattened and polish, a characteristic of the Solo model variants. its crown is a circular-grained, set with a synthetic spinel cabochon. The automatic calibre housed within the versatile 36mm steel is the well trusted Calibre 049


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.
