Joey Ansah wears a Hamilton Khaki Field

Joey Ansah plays Keane, a pharmaceutical executive who discovers that immortal warriors exist and decides to capture one for lab research. It is the kind of villain motivation that only works if the character believes he is doing something rational. In Gina Prince-Bythewood's The Old Guard, Keane wears a Hamilton Khaki Field Titanium Auto, reference H70575733 -- a 42mm automatic in black PVD-coated titanium with a rubber strap.

The Khaki Field is a military lineage watch, descended from Hamilton's World War II field pieces issued to American troops. Putting it on a corporate villain is an ironic touch. Keane is not a soldier; he is a CEO who hires private military contractors while wearing their aesthetic. The titanium case and PVD coating give it a tactical look that suits a man who wants to project power without getting his hands dirty.

Hamilton confirmed this placement on their website. Charlize Theron's Andy wears no identifiable watch in the same film, which means the villain is the one who cares about time. For an immortal, time is irrelevant. For the man trying to harvest immortality, every second counts.
