Kurt Russell wears a Breitling Chronomat

Roland Emmerich's Stargate (1994) sends Colonel Jack O'Neil (Kurt Russell) and the Egyptologist Daniel Jackson through an ancient ring-shaped portal to a distant desert world. O'Neil is the closed-off military man leading the mission, and on his wrist is a steel chronograph on a black strap.

The watch reads as a Breitling, most likely a Chronomat. It is a chronograph, with pushers set either side of the crown, which rules out the Breitling Sirius some accounts have named, since the Sirius is a time-only watch. The brand never resolves clearly enough on screen to read, and the exact reference is unsettled, so it stays a probable Breitling Chronomat rather than a confirmed one.
