I don't understand why a watch would have this shape. My friend thinks that it might be a bookmark, but the tails are a little too thick for that. What is this kind of watch called?

Hello WUS,

This is my authentic Rolex Glidelock clasp, as was originally fitted to my 114060 Submariner. I owned and sold the Sub three times, the most recent in 2021 with the bracelet, but without clasp. This is from that watch. It also includes a genuine Rolex half-link as shown in photos.

I wore this clasp briefly on each of my since departed 14060 Submariner, 214270 Explorer, and 124300 OP41. It fits many models.

I’ve been saving this one, but decided to give someone else a change…
