Valérie Lemercier wears a Cartier Tank Américaine

Welcome Aboard, Eric Lavaine's 2011 French comedy, follows Isabelle, the head of HR at a cruise line who is dumped and fired by her boss and sets out to wreck the company's flagship maiden voyage in revenge. Valérie Lemercier plays her, and her instrument of chaos is a charming screw-up named Rémy, played by Franck Dubosc. On Isabelle's wrist is a Cartier Tank Américaine in yellow gold.

The Tank Américaine is the long, curved version of Cartier's Tank, its rectangular case drawn out to follow the wrist. The French watch site that flagged it here, Montres de Luxe, noted the same model on the film's other lead: Elisa Servier also wears a yellow-gold Tank Américaine. As with Servier, the identification is thin. It rests on that single writeup, the film offers no clear look at the watch, and there is no second source. The brand and model are likely rather than confirmed.
