Look at the clasp before you look at the dial. On a used bracelet the fold can sit proud, the blade can show a pale line, and the end links can click when you twist them. That click is play between the link and the case, and it grows as the pins loosen. Count the gaps you can see from the side. One hairline gap is ordinary wear. A gap you can rock means the end link has been asked to bend in a way it was not shaped for. None of this tells you who first sold the watch. It tells you whether the parts that touch the wrist are still doing their job. Keep the notes next to the model name so the next reader can repeat the same check.

A library page is written by {Site}. A photo post is one person’s notes. Neither authenticates a watch, offers it for sale, or speaks for the name on the dial. These notes are not authentication and not a shop.
