Awards season is prime time for brands to reveal showstopping creations, and the British Academy Film Awards last month certainly provided a stage for the new Cartier Libre Polymorph collection, jeweled timepieces and accessories themed around movement and transformability.

Paul Mescal, a supporting actor nominee for “All of Us Strangers,” accented his look with a black-and-white lapel gem in white gold, garnets, onyx and diamonds, paired with matching cuff links.

And Emma Corrin, one of the evening’s presenters, also embraced the graphic black-and-white scheme — a Cartier signature since 1910 — wearing a ring crafted from four rotating discs of white gold, diamonds and onyx that were engineered to fully stretch or fold. The piece was complemented with a matching ear cuff set.

Cartier Libre Polymorph “is a collection where we constantly push innovation and elevate the outstanding Cartier savoir-faire,” Marie-Laure Cérède, the house’s creative director of jewelry and watchmaking, wrote in an email.

Fans of the brand will be familiar with Cartier Libre, a line that in recent years has been a canvas for Cartier to experiment with its popular watch models and to explore signature design codes. The oval Baignoire watch case, for example, was elongated or rotated onto its side; a Baignoire Turtle watch evoked a tortoise shell with geometric-shape diamonds and sapphires; and a Crash Radieuse timepiece featured concentric, wavelike lines that followed the distinct shape of the Crash, one of Cartier’s most emblematic watches.
