Worn by: Leonardo DiCaprio as Danny Archer
Reference: Breitling Avenger
Brand: Breitling
Leonardo DiCaprio stars as Danny Archer, a Rhodesian smuggler and mercenary who makes a career out of smuggling diamonds. While the film is fictional, it takes place during the Sierra Leone Civil War and portrays the horrors of the diamond trade. In the film, DiCaprio wears a Breitling Chrono Avenger. This piece fits the mold for the film as it has a utilitarian titanium case—a rugged tool watch appropriate for the character's dangerous work in conflict zones.
