Simon Pegg wears a Casio G-Shock Gravitymaster

Halfway through Mission: Impossible Rogue Nation, the BMW carrying Ethan Hunt and Benji Dunn flips and comes down on its roof. Simon Pegg plays Benji, the IMF technician who keeps getting dragged out from behind his monitors into the field he would rather avoid. He is the voice in Hunt's ear for the opera-house job and the underwater break-in, and he is in the passenger seat when the car goes over.

By one watch-spotter's account, the watch on Benji's wrist through that chase is a Casio G-Shock Gravitymaster, reference GW-A1100-1A3. It is a Japanese-made aviation watch and a costly one for a G-Shock: 650 dollars when Casio shipped it internationally in 2013, and the first G-Shock outside the MR-G line to get a sapphire crystal. It runs on light through Tough Solar, resets itself off radio signals with Multi-Band 6, carries a compass and a flyback chronograph, and is built around Triple G Resist, Casio's guard against shock, vibration, and centrifugal gravitational force.

That last defense is the one the film never hands a pilot. Triple G Resist exists for the cockpit, for the gravity pulled in a hard turn, and the only flying in the movie belongs to Hunt, hanging off a military transport as it climbs off the runway. Benji stays on the ground at his keyboard. The one time his g-force watch is asked to earn its name, it is strapped to a passenger in a car rolling onto its roof. In its last years Casio kept it on sale only in Japan, and it now looks all but discontinued.
