Abstract

The case tube (3), through which passes the stem (4) of a mechanism for operating the movement, is screwed into a tapped hole (2) in the case body (1). This tube has an outer shoulder itself having a frustoconical land (10) bearing on an annular edge (11) of the case body (1). The tightening of the tube slightly caulks this edge, thus leading to very high pressures of the tube on the case body which preclude any inadvertent loosening of the tube. <IMAGE>
