Abstract

A moving indicator for an analogue display device, in particular for a timepiece. The indicator includes a multi-layer part including an opaque metal layer and a transparent light guide layer and forming a body and a head of the indicator. The head is centred relative to a rotational axis of the indicator and arranged to receive a luminous flux on the bottom face thereof. A fluorescent material is arranged on the transparent light guide layer at the head of the indicator to absorb at least part of said luminous flux and to re-emit a second luminous fluorescence flux in the transparent light guide layer. Other aspects comprise a set of indicators, a display device and a watch comprising one or more moving indicators.
