Serena Williams set a milestone as she won 2017 Australain open.
She won by defeating her sister Venus and making her 23rd Open title.
Williams took the win while wearing a pretty stunning Audemars Piguet Millenary diamond watch on her wrist.
A long-time brand ambassador for Audemars Piguet, Williams is often seen sporting an Audemars Piguet on her wrist.
During this Open, however, she even wore the watch during play. The solid 18-karat gold watch with diamonds on it may have been the good luck piece.
