The Calibre de Cartier made its debut in 2010, marking the first time Cartier used its own movement in a mass-produced watch. This was a big deal, as previously only a select few high-end Cartier timepieces had this feature. The round case has a modern and bold design, while the classic sword-shaped hands and Roman numerals give it that signature Cartier charm. In 2011, a bracelet option was added to the collection, followed by a chronograph in 2012. A smaller 38mm version joined the family in 2015. The W7100040 model boasts a pink gold case, brown dial, and a 3-link pink gold bracelet.
