#CMT# #/CMT# The timepiece has casing elements constituted of a back cover (2), a middle (1), an opaque dial (3), watchstrap strands, and a bezel (26), where one of the elements is made of transparent/translucent material. The cover, the middle and the bezel define interior volume (4) of a watch case (6) to house a clock movement (M). A light source (10) i.e. LED, is housed in the interior volume, and produces light that passes through a transparent/translucent portion such as middle, of the corresponding casing element. A decorative sheet is arranged above a light guide i.e. optical fiber, of the strands. #CMT# : #/CMT# The transparent or translucent material is chosen from a group comprising plastic material, ceramic material, sapphire and fused silica. The light guide is overmolded in a layer made of silicone or polyurethane. The decorative sheet is made of polymethyl methacrylate. #CMT#USE : #/CMT# Timepiece such as electronic watch e.g. electronic wristwatch. #CMT#ADVANTAGE : #/CMT# The light source produces light that passes through the transparent or translucent portion such as middle, thus providing attractive aesthetic effects to the timepiece in darkness. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a watch case equipped with a light source.
