During his pre-wedding festivities, Anant Ambani, son of Indian billionaire Mukesh Ambani, showed off his expensive Richard Mille watch which caught the eye of none other than Facebook CEO Mark Zuckerberg and his wife Priscilla Chan. A video of the couple admiring the watch has gone viral, with Chan exclaiming "That watch is fantastic, that is so cool." Zuckerberg, who previously stated he was not a fan of watches, said that he might want one after seeing Ambani's timepiece. The watch in question is a beautiful Audemars Piguet Royal Oak Openworked Skeleton worth a whopping INR 14 crore.
