Abstract (en)
[origin: WO2019111195A1] The micro-mechanical horology component comprises contact surfaces designed to slide against corresponding contact zones of another micro-mechanical component in a timepiece; – the micro-mechanical component being manufactured from a fragile material; – the said contact surfaces of the micro-mechanical component being grooved, the grooves being rectilinear and parallel to the direction of sliding; – the said grooves being separated by solid lands of a width of between 0.5 and 50 microns; and – the surface area occupied by the solid lands, referred to as the effective contact area, being comprised between 2 and 70% of the total area of the contact surface.
