Paul Reiser wears a Seiko Ana-Digi

In a bright corridor somewhere above Earth, a man in a grey business suit reaches for a door panel. Everyone near him is in uniform. A uniformed attendant in a peaked cap stands at his shoulder. Carter Burke keys the door, his cuff slips back, and on his wrist there is a Seiko that looks, for a second, like the ones the soldiers wear.

It isn't.

James Cameron's costume department fitted the cast of Aliens (1986) with a coordinated set of Seikos, chosen for the same realistic-future-tech logic that produced the Power Loader and the pulse rifle. Ripley wears the Giugiaro-designed 7A28-7000, a quartz chronograph Seiko built specifically for the film. Bishop, the android, wears its sibling, the 7A28-6000. The Colonial Marines, Hicks among them, wear the Seiko Pulsemeter S234, a digital tool watch that came with a chest strap that could actually read your heart rate, and the prop department issued it in two variants. That makes five distinct Seikos across the film. The marines get a medical instrument. Ripley and Bishop get the chronographs built for the movie. Burke gets the dress watch.

His is the Seiko H556-5050, an analog-digital hybrid from around 1983, a slim band of LCD across the top of the dial with analog hands turning below it. It does almost everything: day and date, a second time zone, an alarm and hourly chime, a hundredth-of-a-second chronograph, an incandescent backlight. It is a relative of the famous 'Arnie', the H558 diver Schwarzenegger wore in Commando and Predator, and the resemblance is close enough to fool you. The two are not the same watch. The H558 is a diver, built for the water. The H556 is the dressier relation, a civilian's idea of a high-tech watch, and that difference is exactly why it sits on Burke and not on a marine.

Look closely and the watch is full of quiet oddities. Its chronograph is worked from the left side of the case, which almost nothing else does. Small studs sit at the four corners of the bezel, like rivets. A 24-hour ring runs inside the dial and a tachymeter runs around the outside. Seiko never reissued it the way it reissued the 7A28 chronographs, so genuine examples are scarce, and anyone who wants this particular piece of Aliens has to go hunting for it.

Reiser plays Burke as everyone's friend for the better part of an hour, which is how the trap closes. He is the Weyland-Yutani man, the one quietly weighing human lives against the price of a live specimen, and the only person in the room wearing a suit. The watch fits him the way the suit does. Tech-forward enough to read as competent, polished enough to read as corporate, and sitting on the wrong side of the room from the people holding the guns.
