Bidirectional: A bezel that rotates both clockwise and counterclockwise. It may have printed or engraved markers, numbers, or directional markers.

Interchangable: A bezel that can be removed and replaced by another bezel. In most cases, a watch with an interchangeable bezel comes as a set.

Slide-Rule: A rotating bezel that is printed or engraved with a logarithmic scale, metric scale, or other scales. It is used with fixed mathematical rules, allowing the wearer to perform directional/navigational or mathematical calculations.

Stationary: A bezel that does not rotate.

Tachymeter (or Tachometer): A bezel that allows the wearer to calculate speed based on travel time over a fixed distance traveled. For this reason, most tachymeter bezels will have markings or scales printed or engraved on the surface.

Unidirectional: A bezel that rotates one way. Most unidirectional bezels rotate counterclockwise. In many dive watches, it is used to measure elapsed time spent underwater.
