Title: Stem detent arrangement for wristwatch

Abstract: A three position detent arrangement for facilitating axial positioning of the rotatable stem of a wristwatch in order to enable the wearer to locate the proper axial position. Frusto-conical surfaces of selectively different included angles are employed to provide steep and shallow slopes for the detent spring, so that the steeper slopes require relatively higher force to move from the intermediate position to either end position. This enables the operator to locate any of the three positions with assurance.
