ABSTRACT:
A wristwatch, altimeter and compass are mounted in two side-by-side, releasably attached frames at least one of which has an arm band for carrying them on a wrist. One of the frames has two subframes for mounting the wristwatch and the compass. Flat, straight-edged flanges project from opposing peripheries of the frames and include a tongue and groove connection so that the frames, and therewith the watch and instrument contained therein, can be separated from or secured to each other by slidably moving the groove and tongue connection of the flanges into and out of engagement. A spring-biased locking member is pivotally mounted on the flange forming the groove for movement between an open and a closed position. In the closed position, the locking member prevents detachment of the groove and tongue connection. The locking member includes a plug which extends into the groove when the member is in its locking position so that the member must first be axially moved before it can be pivoted into its unlocked position to prevent an unintended opening of the lock.
