The International Olympic Committee is reportedly investigating whether Jamaican sprinter Yohan Blake broke any Olympic rules by appearing to wear a custom-made $500,000 watch on the track.

The timepiece in question is by Richard Mille, a high-end French watchmaker, and comes in the Jamaican flag colors of yellow, black and green. Blake was seen wearing the watch in the 100-meter final and 200-meter qualifying.

The IOC's absurd and excessive branding rules stipulate that athletes can only wear brands that are official sponsors. Omega is the official timepiece of the Games. And Richard Mille is obviously not Omega.

Blake took silver in the 100 meters Sunday behind countryman Usain Bolt. He's the defending world champion in the event, but before the Games he was better known as the guy who stunningly beat Bolt twice in the Jamaican Olympic trials. Blake is reportedly set to be a Mille spokesman through 2013.

Other athletes who have been busted for branding violations have received the equivalent of a cease-and-desist order when it came to wearing or using social media to promote unsanctioned gear. So, if punished, Blake will probably face no more than a slap on the wrist. Pun fully intended.

The watch itself is pretty elaborate:

You might be better off using a sundial to figure out the time.
