ABSTRACT:
A watchcase coupling structure including an outer rim and coupling pins adapted to couple a front cap and a rear cap, wherein the coupling pins may be mounted in the outer rim and the rear cap without relying upon a threading-in method. Each of these coupling pins may take various configurations. Specifically, it may be the one which has an eccentricity by an amount corresponding to a margin required to adjust the force with which the packing interposed between the front cap and the rear cap is clamped or the one which is provided on its head with a slant portion to facilitate the operation of mounting. Furthermore, it may be the one which is provided on the front end with a notch or the like or the one which has a flange to prevent the pin from falling off. To employ the pin having the flange, the outer rim is provided with a keyhole-shaped notch and the circular head of the pin is symmetrically cut away to present a pair of parallel surfaces so that the pin head may be soothly guided along said keyhole-shaped notch.
