Store owner wearing a fake

[j10s]

There is a local jewelry store that is an AD for Rolex. I bought a watch from them in 2018, and had been in to browse every now and then. The most recent time I was admiring an exhibition skydweller, and the SA mentioned that the owner has a collection of the full PM skydwellers, and they are awesome. I replied that I noticed the owner had been wearing an AP Royal Oak the last few times. The SA said that the AP was a fake! Seems like the owner was upfront about it to his own staff, but something about a Rolex AD wearing a fake AP doesn’t sit well with me. What do you guys think?
