Blake Lively wears a Hamilton Jazzmaster

Carol Ferris runs Ferris Aircraft, her father's aerospace company, and flies its test jets. Blake Lively plays her in Martin Campbell's Green Lantern (2011), opposite Ryan Reynolds's Hal Jordan. The film was an expensive box-office failure that ended Warner Bros.' first attempt at a DC movie universe.

The watch on her wrist is a large steel Hamilton Jazzmaster chronograph: a dark dial with twin subdials, on a steel bracelet, worn loose over her cuff. It is a men's-sized chronograph rather than a dress watch. The brand is not legible in the available stills and the only catalog listing comes from an aggregator, so the exact Jazzmaster chronograph reference is not pinned down, but the case, the twin subdials, and the steel bracelet place it in Hamilton's Jazzmaster line.
