    摘要: A system including two components intended to be in friction contact with each other in a given direction, wherein the friction occurs in a functional area, wherein the system is at least one of the two components including, on a surface in the functional area, a texture formed of a series of troughs of rounded shape separated by peaks or a series of bumps of rounded shape separated by troughs, the troughs extending parallel in the given direction and allowing for the evacuation of debris produced by friction and serving as a reservoir for a lubricant. A method for manufacturing at least one component or a mold by the DRIE (deep reactive ion etching) process, wherein surface defects on the sidewalls machined by the DRIE process are used to form the troughs.

    摘要: A mechanical or electromechanical timepiece including a watch case delimiting an internal volume, the watch case including a back delimiting the watch case at the bottom; a crystal closing the watch case at the top, the crystal defining a useful display aperture; a middle part connecting the back and the crystal to one another; a horological movement housed in the internal volume of the watch case; at least one hand for displaying information visible via a useful display aperture and rotated with respect to the watch case by the horological movement with at least one driving belt extending at least partially in the useful display aperture, the timepiece includes the internal volume of the watch case filled with a fluid wherein at least one driving belt is submerged, and wherein the driving belt is made of a material wherein the optical refractive index is equal or substantially equal to that of the fluid.
