Abstract (en)
[origin: EP1666992A1] The timepiece has an optical device with a set of optical extractors provided in one of extended sides of an optical guide. Each extractor has preset geometric characteristics and a reflection surface (20). Light sources (8) are disposed with respect to a lateral surface (12) of the guide in a predefined direction for transmitting light inside the guide and cooperate with the surfaces to form a figurative image. The figurative image is defined directly with respect to the geometrical characteristics, by reflection of light in the reflection surfaces.
