It looks like Dwayne "The Rock" Johnson is wearing Breitling Transocean Chronograph Unitime watch in Episode 2 of Season 1 of the HBO tv series Ballers. Hopefully in the next few episodes we can see a better shot of the watch to find out if it really is the Breitling.

The Breitling Transocean Chronograph Unitime comes in different colors, but the one worn by The Rock looks like the one with Red Gold case, Polar White dial, and a brown or black leather strap.
