Tommy Lee Jones wears a Hamilton Ventura

In the Men in Black films the Hamilton Ventura is issued like a sidearm. Every agent wears one, in every film since 1997, and Tommy Lee Jones's Agent K has carried the same asymmetric shield-cased watch from the start. Men in Black 3 hands most of its screen time to Josh Brolin as the young K in 1969, but the present-day scenes that bracket the film put Jones back in the black suit with the Ventura on his wrist, the men's quartz reference H24411732, a modern remake of the watch Hamilton launched in 1957 as the world's first electric watch.

The watch is documented down to the individual prop. The Ventura that Jones wore as Agent K was later catalogued and sold by Propstore as his screen-worn piece, a steel triangular case on a black leather strap, its dial crossed by a wavy silver line from nine to three.
