In the movie Blood Diamond, Leonardo DiCarpio wears a Breitling Chrono Avenger watch, black dial and solid titanium 44mm case on a brown calf leather strap.

Sometimes the dial looks blue, but this blue reflection from the sapphire crystal is the anti-reflective coating of the crystal, which produces a bluish hue when viewed at certain angles, as the the image on the left of a Chrono Avenger illustrates perfectly.
