Mayweather finished his boxing career with a flawless record of 50 wins from 50 fights. He retired undefeated, as the king of the pay-per-view format, and with over a billion dollars in career earnings.
Mayweather's motto in the gym has always been "hard work, dedication", and it looks like he is just as dedicated to spending and shopping as the 41-year-old showed off two shiny, diamond-encrusted custom watches on his Instagram account.
The first is a diamond and gold watch, which also appears to double-up as a serpentine bracelet that wraps around his forearm.
The second watch, from luxury Swiss manufacturer Audemars Piguet, has also been customised with countless diamonds.
Mayweather invited his Instagram followers to guess how big the accompanying ring was. He said: "The timepiece is 41mm, so how many carats is the ring?"
Just two months ago Mayweather published photographs of an $18 million (R260 million) watch, dubbed "The Billionare" by jeweller Jacob&Co, made of 18k white gold and finished with 260 carats of diamonds.
Though Mayweather is retired, he still has a number of income streams thanks to his strip club business, Girl Collection. He also has an emerging real estate empire and claimed he was working on One Vanderbilt— a skyscraper currently under construction in New York City.
