What is an SEL?
Solid End Links (or SEL) refers to the final link on select modern Rolex bracelets. On these SEL bracelets, the final link is made from a solid piece of metal where the bracelet attaches to the watch’s case (or head). This new design makes for a stronger bracelet and a cleaner look. On older bracelets, they utilized a hollow end piece to attach the bracelet to the watch’s case.
