Flaunting the watches on Instagram, the unbeaten former world boxing champion said he takes a watch for every day of the week when on holiday, including his $18m Jacob & Co 'Billionaire' piece.
It is is hard to say who loves diamond-encrusted watches more: Floyd 'The Money' Mayweather or Beverley Hills jeweler to the stars Peter Marco.
Mayweather bought the watch from Tadashi Fukushima, calling him “the best jeweler in the world.”
The design of the Big Bang Unico TMT is inspired by the black trunks and gold lettering of Mr Mayweather's boxing shorts.
World's richest boxer demonstrates a collector's knowledge for limited edition watches.
