Retired professional mixed martial artist and boxer, Conor Anthony McGregor, has shown off a very expensive casino wristwatch he got as a gift for his 32nd birthday.

The Astronomia Casino watch made by Jacob & Co. has a price tag of an insane $620,000, which is roughly N240 million.

The expensive piece of jewellery has a globe-shaped ceramic ball and a 1-carat Jacob-cut white diamond which constantly rotates so you can see it twinkle!

Jacob & Co. also says the watch has this feature — “When the pusher at eight o’clock is actuated, the wheel spins just like in Vegas or Macau.”

Conor and his longtime girlfriend, Dee Devlin, are celebrating his special day in their private villa located in French Riviera.

The retired MMA champions new wristwatch has a similar price tag to the new Lamborghini Aventador SVJ that Real Madrid star, Eden Hazard showed off yesterday.
