Tommy Lee Jones wears a Hamilton Pulsar P2

For most of Men in Black II, Agent K wears the watch the franchise is built around: the angular Hamilton Ventura. In one close-up, though, the watch on Tommy Lee Jones's wrist is a different Hamilton entirely. It is a Pulsar, the brand's 1970s LED digital watch, its black face glowing with blue numerals above the word HAMILTON. The cushion-shaped steel case and integrated bracelet are pure 1972, the year the Hamilton Pulsar arrived as the first electronic digital watch sold to the public.

Hamilton has supplied the Ventura to every Men in Black film, and for the 2002 sequel it tied in the Pulsar as well, releasing a Men in Black II Pulsar P2 edition alongside the Ventura. So Agent K wears both watches across the film: the triangular Ventura in the agency scenes, and this digital Pulsar in the shot where its display glows blue.
