Josh Brolin wore a Hamilton Ventura in Men in Black III, playing the younger version of Agent K.

Brand: Hamilton
Hamilton's alliance with the Men in Black movies was a very clever one. In Men in Black III, the original Hamilton Ventura is highlighted on the wrist of Will Smith as Agent J. Still part of Hamilton's current collection, this model originally rose to fame thanks to Elvis Presley wearing one in Blue Hawaii. Not only did these watches make sense for the characters in the movies, their modest price tags made them accessible to a larger group of consumers, making the commercial impact for the brand all the higher.

Agent O, head of the Men in Black organization, wears the Hamilton Ventura Quartz in a smaller 24mm x 36mm size. The watch features the iconic shield-shaped design with black dial that made watchmaking history in 1957 as the world's first electrical, battery-powered watch. This faithful tribute to the original mirrors the pioneering shield-shaped celebration of Mid-Century Modern design. With its daring and distinctive styling on a black leather strap with butterfly clasp, the Ventura remains an icon more than 60 years after launch—appropriate for the formidable leader of the agency protecting Earth from alien threats.
