Rick Ross has got to be the best boss ever ... because when his album hit number one on the charts ... he bought each of his closest boys a sick, insanely expensive watch to celebrate.
According to our sources, Ross hit up jeweler Rafaello & Co in NYC last week and dropped a cool $250k total on six watches for a few of the artists who appeared on his album "Mastermind."
Among the lucky recipients of an Audemars Piguet watch: DJ Khaled, Meek Mill and Wale.
We're told Ross picked out the watches himself and had the cash wired to the store.
Rick Ross ... a good friend to have.
