Jamaican Olympic teammates and training partners, Usain Bolt and Yohan Blake, will compete in the 100 meter dash Olympic final tonight, to see who is the best in the world. (They will also be competing against 6 others, but are considered the favorites). Needless to say, they are used to competing against each other. In fact, Blake beat out his fellow teammate in the 100 meters at last year’s world championships after Bolt was disqualified for a false start.

Both Olympic sprinters are watch ambassadors: Bolt represents Hublot and Blake represents Richard Mille. Moreover, as is the case with all of Richard Mille’s ambassadors: Bubba Watson, Rafael Nadal, Felipe Massa – Blake will be wearing an ultra-light RM timepiece during the race (see picture above, right).
