Mayweather makes it no secret of his lavish retirement after buying mansions, private jets and even running a strip club.

And he continues to open the cheque book this time landing a new timepiece aptly named "The Billionaire Watch."

Showing off the piece of jewellery he said: "This is my new timepiece, it's called 'The Billionaire Watch'.

"If you don't know about it, google Billionaire Watch. That's $18m (£13.75m) on the price-tag.

“I bought this watch from the best jeweler in the world, hands down @tadashi1980.

 It's called "The Billionaire's Watch" and is just the latest in his lucrative collection

"He has better prices than any other jeweller that I’ve ever done business with ever and trust me, I’ve bought jewellery from every jeweller in NYC, Vegas, LA, Detroit, Houston and Miami."

Mayweather continues to hold the reign of the wealthiest sportsman as released by Forbes.

The 41-year-old took home £212m in 2017 over double more than second best Lionel Messi.

And it appears he just can't help himself when it comes to spending his fortune.

Boxing legend Floyd Mayweather shows off huge wads of cash after private fashion store shop

This month he uploaded two Instagram videos showing just how much cash he has lying around.

In one the American shows a clip with stacks of notes piled on a bed, barely leaving room for anything else.

Each wad is a pile of 100 dollar bills and it is impossible to work out the exact amount but it remains well into the thousands.
