Mireille Darc wears a Cartier Tank

Mireille Darc plays Peggy Lister, the woman at the center of Georges Lautner's Icy Breasts (Les Seins de glace, 1974). Claude Brasseur's novelist, François Rollin, falls for her on the Riviera, while Alain Delon's Marc Rilson, her lawyer, controls her closely and tells Rollin she is mad and killed her husband. Adapted from Richard Matheson's Someone Is Bleeding, the film leaves how much of that is true unresolved.

A French watch site identifies her watch as a yellow gold Cartier Tank. Louis Cartier designed the Tank in 1917, its case said to echo a Renault tank seen from above, the upright bars on each side standing in for the treads. By the 1970s it was a settled classic, worn as a dress watch rather than a statement. The identification comes from that single source, and the Tank is not visible in the surviving stills.
