Actor Gwendoline Christie spotted wearing a Cartier

On the set of Netflix's Wednesday, costume designers made a pointed choice strapping a Cartier Tank Louis Large to the wrist of Gwendoline Christie's Principal Larissa Weems — a character whose wardrobe is constructed around controlled power and institutional elegance. The watch is barely glimpsed, but the rectangular silhouette, dark leather strap, and slim profile are unmistakable against Christie's tailored green tweed sleeve.

The Cartier Tank Louis Large in 18-karat rose gold, reference WGTA0011, measures 33.7 × 25.5 mm — generous for its era of design, modest by contemporary standards. It houses the manual-winding Cartier Calibre 430 MC, a movement built entirely in-house after Cartier's significant investment in manufacture capability during the 2000s. The silvered dial carries Roman numeral indices printed beyond the inner guilloche-engraved chapter ring, blue-treated steel sword hands, and the sapphire cabochon crown that has defined Tank aesthetics for over a century. The case is mounted on a hand-stitched dark grey alligator strap with rose gold ardillon buckle.

Collectors regard the Tank Louis as the purest expression of the original 1917 design Louis Cartier derived from the top-down silhouette of a Renault FT tank. Unlike the Tank Américaine's curved case or the Tank Française's integrated bracelet, the Louis retains the flat, uninterrupted rectangular form with protruding brancards — the side rails that visually anchor the lugs. Rose gold examples have gained particular traction in the secondary market due to their warmth against the silvered dial and relative scarcity compared to yellow gold references.

Gwendoline Christie, best known as Brienne of Tarth in Game of Thrones, brings considerable screen presence to Wednesday, and the prop department clearly understood that a character like Weems would wear something historically weighted, not fashionably loud. A Tank Louis says establishment, not aspiration — precisely the psychological note the role required.

At retail, the Cartier Tank Louis Large WGTA0011 in rose gold lists at approximately $8,900 USD. On the grey market, demand for rose gold Tank Louis references has kept secondary pricing close to or marginally above retail, a sign of steady collector appetite rather than speculative heat — which, much like the watch itself, speaks to quiet, enduring confidence.
