Abstract
A device includes a case having a case sidewall defining a circular receiver having a receiving opening and a central axis. A device body, which is waterproof in one or more applications, includes a sidewall defining a receiving aperture. A crown stem includes a push button disposed within a duct of a threaded bushing and one or more O-rings disposed about the actuation stem to allow translation of the actuation stem in the duct while preventing liquids from passing through the duct. The crown stem inserts through the aperture in the case so that the threaded bushing can hermetically seal the receiving aperture when the device body is inserted into the circular receiver to prevent the liquids from entering the receiving aperture.
