Abstract
In order to prevent the face of a watch with light-emitting diode display from appearing, in the non-excited state, in the form of an unaesthetic broad dark red spot, the glass comprises two zones of different nature: a first (7) having optical filter properties, the second (6) devoid of such properties. For this purpose, a first part (5a) making up the glass, of a transparent material, has, in its lower face, an excavation filled in with another part (5b) having the nature of an optical filter. The thickness of the glass is approximately the same in both zones. <IMAGE>
