Simon Pegg wears a Tissot T-Touch Expert Solar

The camera in Rogue Nation pushes in tight on Benji Dunn's wrist, close enough to read the dial: TISSOT 1853, ringed by a crystal that labels its own functions, METEO, ALTIMETER, COMPASS, ALARM, TIMER. In the digital window below the hands, a timer reads three minutes. Simon Pegg plays Benji, the IMF's technician and Ethan Hunt's man at the keyboard.

It is a Tissot T-Touch Expert Solar, from the line Tissot built around a touch-sensitive crystal. Press the glass over one of those labels and the watch becomes that instrument: an altimeter, a compass, a barometer that reads the weather, a chronograph, a countdown timer. It runs on light rather than a battery, and the case and bracelet are titanium. The reference most often cited for the on-screen watch is T091.420.44.051.00.

Tissot sits in the affordable middle of the Swatch Group, a tier or two below the group's Omega, and the T-Touch is a tool rather than a status watch. The contrast is there in the same film: Jeremy Renner's character wears a Rolex Submariner, and Benji, the man who builds and breaks the gadgets, wears the watch that is itself a gadget.
