Leonardo DiCaprio is not known as a watch investor. Years ago he was seen with a Rolex Daytona and a Tag Heuer Aquaracer before that. Recently he was spotted with a Patek Philippe Nautilus with a Tiffany-blue dial.This is undeniably the hottest watch to come out in quite some time, attracting major celebrity Watch Guys like Tiffany ambassador Jay-Z, who was the first to show the watch off in public, and LeBron James, who got something nice under the tree on Christmas Day.
