Check Out Serena Williams' $75,000 Watch With 323 Diamonds (PHOTO)

Serena William's swag just reached new levels -- 'cause the tennis superstar got herself a new luxury watch that comes fully equipped with 323 DIAMONDS!!! It's called an Audemars Piguet Millenary timepiece -- made with 18-carat pink gold, a black mother-of-pearl dial and 323 brilliant-cut diamonds! The watch usually runs around $75K. It certainly is a watch that only rich and affluent sportsmen can afford, Ghana Black Stars captain, Asamoah Gyan and NBA superstar Lebron James were both seen wearing one recently. A rep for Audemars -- popular with celebs like Jay-Z -- says the luxury watchmaker has a relationship with the tennis champ ... but this watch wasn't a freebie from them. "Serena is a friend of the brand but that isn't a piece we gave her," the rep tells TMZ Sports. So, did Serena drop $75k on gift for herself? It's not like she can't afford it.
