Abstract
A cylindrical bearing segment of a preferably metal sleeve is positioned within a hole in a watch-movement plate. A portion of the sleeve intended to project inwardly beyond the plate is divided by a lengthwise slot into two claws which yield so that the sleeve can be inserted in the hole by simple axial pressure. When the dial is to be fitted in place, a dial-foot is inserted in the sleeve, pushing the claws apart by pressing against inner bulges at the ends of the claws, these bulges then pressing laterally against the dial-foot and locking it firmly in place.
