Watch comprising an analogue display lighting device

A watch (2, 42, 82) comprising a case (6) fitted with a glass (78), a movement, an analogue display device, a flange (14, 50), the inner lateral surface (28, 52) of which laterally defines a display space (70) for the analogue display device, and a lighting device (20) arranged to be able to provide light in the display space through said inner lateral surface, the lighting device comprising at least one light source (10, 64) powered by a source of electricity on the watch;

• wherein the lighting device comprises an at least semi-transparent element (12, 12a) forming the flange or surrounding the flange, which in the latter case is at least semi-transparent in the direction of the display space for light supplied by the at least one light source and incident on an outer lateral surface of this flange;
• and
• wherein the at least semi-transparent element is arranged above said at least one light source and has:
• a lower injection surface (22) which is configured to enable injection into the at least semi-transparent element of a major part of the light (30) provided by said at least one light source,
• a lateral exit surface (26) through which at least a major part of the light injected into the at least semi-transparent element can exit this element to penetrate into the display space directly or respectively through the at least semi-transparent flange, and
• an intermediate surface (24) configured to receive, with no prior reflection, at least a major part of said injected light, and to substantially reflect said at least a major part of said injected light towards the lateral exit surface.
