Coussin de Cartier is the embodiment of dreams. The standout feature of the Cartier 2025 high jewelry watch model WCJS0003 is undoubtedly its latest case design-the Coussin de Cartier cushion shape. In the realm of high jewelry watches, the cushion shape traditionally refers to a square design with rounded corners. However, Cartier has cleverly transformed the four corners into swirling lines adorned with gemstones. Upon closer inspection, this design not only confuses conventional geometry with its whirlpool effect but also, combined with the swirling lines of the case, creates a sensation of being immersed in a dreamlike world reminiscent of Inception, where reality seems turned upside down. It's a mesmerizing experience; the square is no longer merely square, and within its shape lies an enchanting roundness.The Coussin de Cartier cushion-shaped watch also features various styles with different sizes of gemstone settings. This new case design, resembling a whirlwind, showcases a beautiful interplay of creative geometry and imagination, marking another exquisite achievement by Cartier in the realm of design.
