Abstract
The bezel of the watchcase is made up of an annular zone supporting the glass and of four pillars extending radially outward at 45.degree. angles relative to the 3 o'clock-9 o'clock and 6 o'clock-12 o'clock axes. At the same positions the caseband has four indentations into which the pillars are fitted so as to come in contact with the inside face of the back. Screws fix the back to the bezel, thereby compressing two gaskets and securing the caseband between those two parts. At the location of 3 o'clock, the caseband is pierced by a radial passage provided for a control stem.
