A coin-edge bezel is a watch bezel with fine, evenly spaced grooves cut by machine around its rim. The grooves give the fingers something to grip when turning the bezel or holding the watch. On a fixed bezel, the texture is mostly decorative and stands out against the polished parts of the case.
What does a coin-edge bezel do?
The bezel is the ring that frames the dial. It normally sits just outside the crystal. Cutting grooves into its rim changes how it feels and how it looks. On a bezel that actually rotates, the ridges do a practical job. They stop fingers slipping as the ring is turned. On a bezel that does not turn, their role is mainly visual. The ridged band contrasts with the smooth, polished surfaces around it. Either way, the texture adds interest to the case and suggests traditional craftsmanship.
Where it comes from
The name comes from coins. Their rims are often reeded, which means they carry a ring of fine ridges. A watch bezel cut in the same way looks much the same, so it took the same name. The style is far from new. In 1935, Heuer listed coin, or coin-edge, as one of four bezel styles. The other three were bevelled, curved (concave) and stepped. Today the ridges appear on Rolex’s Perpetual 1908 dress watch line, where the bezel carries a fine coin edge.
Not to be confused with
Rolex Oyster cases have a milled edge that looks very like a coin edge. It sits on the caseback, though, not on the bezel. A grooved caseback does not mean the watch has a coin-edge bezel. The same grooved texture can also be cut around the rim of the case itself rather than the bezel. In that case the case has a coin edge, but the watch does not have a coin-edge bezel.
