Cartier Caliber 1917 MC

The Cartier caliber 1917 MC is a small and slim tonneau shaped manual-wind mechanical watch movement. The caliber number is named after Cartier’s founding year: 1917. This movement helped the brand solve the problem of being able to fit a round movement in Cartier’s rectangular Tank style watches. The elongated design means it can be used in such cases.

Anti-magnetic?

While the movement itself is not anti-magnetic, Cartier states that they use a paramagnetic alloy shield between the movement and case to protect it from magnetism.
