Antonio Brown Cops Insane ‘The Godfather’ Watch W/ 666 Round Diamonds

Antonio Brown‘s decided to treat himself following the success of his new song and dance by copping an insane “The Godfather” watch … that’s filled with 666 diamonds!

TMZ Sports has learned the former NFL wideout hit up Jacob and Co. earlier this week to pick up the timepiece … and the classic mob film-inspired watch came pretty epic.

We’re told it features a miniature Vito Corleone (played by actor Marlon Brando) in the middle of it with his iconic black tux. It also has a hand-painted black piano … and a Swiss music box that plays the first 120 notes of the movie’s theme song!

And, get this … the music box is played by two cylinders that are paved with 666 brilliant round diamonds and 18k of rose gold!

We’re told AB also got a second watch on the shopping spree — a rose gold Bugatti Chiron Tourbillon that has a crankshaft that turns 16 piston pumps up and down … like a real engine.

The Super Bowl champ spent somewhere in the neighborhood of $800k for both watches … and even though AB hasn’t earned any money on an NFL field in a few months, he has collected over $80 million in his 12-year NFL career.
