Ben Affleck wears a Breguet Tradition

Ben Affleck's Bruce Wayne wears a Breguet Tradition Fusée Tourbillon, reference 7047PT, through most of Zack Snyder's Batman v Superman: Dawn of Justice (2016). It is a platinum tourbillon that ran about 190,000 dollars, and Breguet confirmed it as the watch on Affleck's wrist.

Abraham-Louis Breguet founded the house in 1775. The Tradition line, launched in 2005, lays the movement out on the dial side: balance wheel, barrel, and gear train arranged across an open face. The 7047 adds two old ideas to that display, a tourbillon and a fusée-and-chain that feeds constant force to the escapement, an 18th-century device modern watchmaking mostly engineered away. On Wayne's wrist it is the opposite of discreet, the machinery worn on the outside.
