The Cartier 1847 MC movement represents a significant step in Cartier’s evolution as a serious watchmaker. Introduced as an in-house automatic movement, it was designed to give Cartier more control over its watchmaking processes and reduce reliance on external movement suppliers.If you're wondering when Cartier started using the 1847 MC movement in the Ballon Bleu, the answer lies in 2018, when Cartier transitioned some of its Ballon Bleu models from ETA-based movements to its own in-house caliber.
