A method for providing illumination to a timepiece includes providing an array of LEDs arranged around a periphery of a substantially planar surface such that each LED in the array of LEDs emits light toward a center of the periphery. The substantially planar surface overlays a timepiece movement having a watch hand pinion that extends through a hole in the substantially planar surface. The substantially planar surface is bounded by a casing of the timepiece. The method also includes situating each of the LEDs in a diffuser layer extending across the substantially planar surface to scatter light emitted by each LED. The method also includes applying power to the array of LEDs such that each LED is driven at a current lower than a specified current for normal operation of the LED.

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.

A watch including a watch case provided with a case middle, the case middle carrying an element provided with at least one index and defining an inner cavity. The watch further includes at least one pair of electrodes and at least one light source device connected to the electrode pair and arranged opposite the index, the electrodes of the electrode pair being fixed inside the inner cavity, the element being water permeable such that, when the watch is immersed in seawater, the seawater can penetrate the inner cavity so that the electrode pair and the seawater form an electrochemical cell, for powering the light source device.

A decorative item including an element made at least partly of a metallic, polymeric or ceramic based material and including a face visible to an observer, at least one light source external or internal to the element, the decorative item further includes at least one optical fibre embedded in the material of the element, the optical fibre serving as a guide for the light from the light source in order to produce, during use, a light effect on the visible face of the element. A method for manufacturing the decorative item is also disclosed.

A display panel includes a plate-shaped decoration member including a shading part and a light transmission part formed within the shading part, as well as a plate-shaped reflection member disposed on a back side of the decoration member. The shading part and the light transmission part create a fine pattern in a plan view. The reflection member is configured to reflect light. The decoration member is disposed on a front surface of the reflection member.
