Chatunga Bellarmine Mugabe splashed the alcohol on the timepiece while partying in a nightclub in Sandton, South Africa, with his brother Robert Jr.
The video apparently showed him pouring Armand de Brignac Ace Of Spades gold champagne, which reportedly costs £200, on his watch.
It is believed Chatunga had claimed earlier on Snapchat he was able to afford the timepiece because his ‘daddy run the whole country’, News 24 reported.
Almost 75% of people in Zimbabwe are living below the poverty line so the incident did not go down well with people who saw the video online.
A Twitter user called Mugabe’s sons ‘spoiled and rotten brats’.
Another person added: ‘Mugabe’s son bragging about wearing $60 000 jewellery yet majority suffering?’
