Yohan Blake's $500k watch

That would be about 75million in Naira. The second fastest man in the world in a watch designed specifically for him to wear at the Olympic Games by designer Richard Mille. The watch is a diamond encrusted customized sports watch in the green and yellow colours of the Jamaican flag.

But Blake might face some kind of sanction from the International Olympic committee (IOC) for wearing the watch because Richard Mille is not an official Olympic sponsor. Omega is the official watchmaker of the Olympic Games. Athletes are supposed to only wear clothes from sponsors
