When Taylor Swift and Travis Kelce announced their engagement this summer over social media, it wasn't just Swift's ring finger that fans zoomed in on. The online watch marketplace Chrono24 told WatchPro magazine that searches for her timepiece-a diamond-studded yellow-gold number that turned out to be a Cartier "Santos Demoiselle"-surged by 2,000 percent over the next two days.
As of 2025, the Panthère has been prowling around Cartier jewellery for a rather satisfying 111 years. Its distinct markings - generally executed in white diamonds and onyx, although sometimes in yellow gold too - were first recreated on a watch. The actual form of the big cat, meanwhile, debuted on a cigarette case made in 1917 and given by the family scion Louis Cartier to formidable jewellery designer Jeanne Toussaint, who was also his lover.
A new exhibition at Paris' Musée des Arts Décoratifs celebrates the movement's centenary, while showcasing its continued relevance today. Spread across three floors, the more than 1,000 pieces on show span from the elaborate - think embroidered silk evening dresses by Madeleine Vionnet and Frantz Jouradin and glass and silver creations by René Lalique - to the everyday, such as cups and saucers, coffee pots, and even a toaster, a result of departments stores putting the Art Deco style into mass production.
Cartier's share of the total purchases by Gen Z on Chrono24 rose from 1.7% to 6.8% over a seven-year period as of the first half of 2025, according to the report. That share outpaces the brand's overall growth on the site during the same period. Three models are driving the interest from Gen Z: the entry-level Tank, the sportier Santos, and the dressy Panthère.
