The Internet, and auction aggregators specifically, have made watches and information accessible to anyone, and this is mostly a good thing. To be clear, there are also still deals to be, but it just gets harder every day, and link they don't usually say "Patek" or "Rolex" on the dial. But, there's still expertise and an art to inspecting and evaluating these watches, and it often needs to be done in person. It's important to know what you don't know.
