Abstract

The gold calibre (5) includes the annular wall (8) which surrounds the movement (1) and two diametrically opposite radial arms (10) which end in pintles (11). The back (6) is fixed by a catch to the lower edge of the wall (8) by the peripheral rim (13) whose upper surface (20) forms a shoulder which extends beyond the wall (8). A sapphire auxiliary element (7) which has notches (16) for the passage of the arms (10) and whose upper face is faceted is held in place between the upper peripheral rim of the calibre (5) which extends flush with the lower surface of the arms (10) and the shoulder (20). <IMAGE>
