Floyd "Money" Mayweather has nothing but time (and money) on his hands following his most recent payday - a reported $9 million purse for an exhibition boxing match against Tenshin Nasukawa, which lasted all of 139 seconds. 

In anticipation of his next "pay-cation" the undefeated boxing legend took to instagram to show off his collection of luxury watches that accompany him on any trip he makes.

According to Floyd, he brings a watch for each day when he travels and if he really feels like stunting he'll pull out the "one and only" $18 million timepiece. 18 million American dollars.

In total, Mayweather recently showed off 41 luxury watches, all of which are tightly secured in briefcases. 

Check out the footage in the video embedded below.

According to TMZ, the $18 million watch is actually called "The Billionaire Watch" and was made by Jacob & Co. back in 2015. It features 239 emerald-cut baguette diamond stones, each weighing up to 3 carats.

Per TMZ:

"Floyd says he bought the watch last summer from a Japanese jeweler named Tadashi Fukushima -- and claimed he'd never buy any jewelry from anyone else ever again."
