Messages spreading on social media and messaging apps claimed that Clint Lim Way Chau was seen wearing a watch from designer brand Richard Mille, which costs US$89,995 (RM349,000).
The 25-year-old Royal Melbourne Institute of Technology accounting graduate showed his watch to The Star on Tuesday (March 27), which turned out to be a "T-Race" model from Swiss manufacturers Tissot.
A check showed that the watch can be purchased online in Malaysia at a discounted price of RM1,880.
The design and faces of both watches were completely different, with the only similarity being a red wrist strap.
"That is not my watch. How I wish I can have that kind of watch," he said when met outside the Penang High Court on Tuesday for his father's corruption trial.
Clad in a green shirt and wearing sunglasses, Clint arrived in the morning and left the courthouse during proceedings to have a drink at a nearby cafe.
