alternative forms: click-stop bezel, detented bezel

What this means is a bezel that can be moved to several distinct positions and is held in each position by a detent (click-stop) mechanism. This is desirable for a time zone bezel, since it should be adjusted in units of hours (or 30 minutes if the designers thought to accommodate India and Newfoundland).
