The present invention relates to a mechanical or electromechanical timepiece. The mechanical or electromechanical timepiece comprises a watch case (2) delimiting an internal volume (4). The watch case(2) includes: a back (6) delimiting the watch case at the bottom; a crystal (8) closing the watch case at the top, the crystal (8) defining a useful display aperture (12); a middle part (10) connecting the back (6) and the crystal (8) to one another; a horological movement (22) housed in the internal volume (4) of the watch case; at least one hand (18) for displaying information visible via a useful display aperture (12) and rotated with respect to the watch case by the horological movement (22) with at least one driving belt (30) extending at least partially in the useful display aperture (12), the timepiece includes the internal volume of the watch case filled with a fluid (34) wherein at least one driving belt (30) is submerged, the driving belt (30) is made of a material, and the optical refractive index is e
