In the movie Cosmopolis, the main character Eric Packer, played by Robert Pattinson, wears a Chanel J12 Chromatic Classic Automatic 41mm H2934 watch.
Throughout the film, Robert Pattinson wears only one outfit: a black two-button notch-lapel Signoria suit by Gucci, a Gucci fitted white cotton shirt, a slim black silk tie, a leather belt with silver buckle detail and black leather lace-up dress shoes, all from Gucci. The Chanel watch is a nice addition to this stylish outfit.
The Chanel J12 Chromatic Classic is made from titanium ceramic, a new material that is highly scratch-resistant and has a hardness close to that of sapphire. Its unique color and sparkle are obtained by adding titanium to ceramic and then polishing with diamond powder. The watch comes in three sizes, 33mm (ref nr H2978), 38mm (ref nr H2979) and the 41mm (ref nr H2934) which is seen in the film.
