What does it mean

[sgucla]

A long time ago when my hubby and I were much younger and very very inexperienced we decided to buy him a diamond dial DJ. After searching the Internet we found a dealer who seemed reputable. We met him in a brick and mortar store in Laguna and handed over our cash for the watch. When we examined be warranty later....yes I know later being the operative word....it turns out this watch's warranty said it came with a blAck diamond dial....ours was the copper diamond dial which is what we wanted. The watch has been authenticated and services at a local AD by their own watch guy. I'm
Not worried about authenticity but I'm curious as to what happened? Did he buy an after market dial and swap it out? Also curious what happens if I ever want to sell it or if I should want to send it in to rolex?
