The former five-weight world champion is currently enjoying the fruits of his labour in the UAE – making the most of the high-end designer shops and sports cars on offer.
And the watch junkie has been flaunting his diamond encrusted Rainbow Tourbillion Audemars Piguet timepiece during the trip.
Mayweather showed off the jaw-dropping watch while posing for an Instagram snap, in which he donned an expensive-looking Louis Vuitton jacket.
The 44-year-old wrote: “The swag is different because the bag is different.
“It’s just a 1 of 1 ALL FACTORY rainbow Tourbillon A light $2,000,000.”
Mayweather’s followers were quick to comment on his insane watch, with one saying: “Sheesh.”
Another said: “You hurtin’ ’em, Champ.”
And another said: “Bruh clean.”
One remarked: “Something light for today.”
Mayweather’s third exhibition will be held on the Burj Al Arab Jumeirah’s Helipad four days before his birthday.
He wrote on Instagram: “February 20th, we haven’t chosen an opponent yet but I look forward to it and hopefully we give you guys something to see.”
