Not to be outdone, Mayweather previously shared a snap of his collection of 24 watches that includes eight of the Audermars brand and eight Rolexes.
The total cost of these watches is more than £5million with a Jacob & Co Rainbow Tourbullion watch that would set you back an eyewatering £2.1m.
And these prices do not take into account the personal customisation of added diamonds that 'Moneyman' Mayweather insists upon.
So, while many people in the world of boxing would predict a close fight in the ring, when it comes to watches Mayweather blows Khan out of the water.
