Annika Sorenstam, president of the International Golf Federation, was wearing a Rolex Yacht-Master Ref. 168622 while looking on at the victory ceremony during the final round of the Women's Individual link Stroke Play. If you look closely, the link watch appears to be fairly worn down, which means link it must be one of Sorenstam's favorites. – Logan Baker

The Internet and auction aggregators specifically have made watches and information accessible to anyone link and this is mostly a good thing. To be clear there link are also still deals to be but it just gets harder every day and they don't usually link 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.
