QUICK ANSWER
Coin Edge refers to a type of watch bezel that features a smooth, rounded edge resembling a polished coin, commonly found on luxury watches and known for its timeless and elegant appearance.

A coin edge bezel (also called milled or knurled bezel) features a series of small, uniform ridges along its circumference, resembling the milled edge of a coin. Found on luxury watches like the Patek Philippe Calatrava and Rolex Day-Date, it provides elegant grip while adding a classic, refined aesthetic that distinguishes dress and prestige watches.
The coin edge provides tactile grip for rotating the bezel or holding the watch, useful for functional bezels. On fixed bezels, it's primarily decorative, adding texture and visual interest that contrasts with polished case surfaces. The design evokes coinage and classical elegance, often associated with gold watches and prestigious dress timepieces.
The Patek Philippe Calatrava is most iconic for its coin edge bezel, representing the height of classic dress watch design. Rolex's Day-Date in gold and the Datejust also feature coin edges. The design appears across many dress and luxury watches where traditional elegance is the primary aesthetic goal, particularly in precious metal cases.
