The invention proposes an analogue display member (10) fitted to a timepiece, of the type including a main body in which an arbor hole is arranged, characterized in that the main body is made of silicon based crystalline material. The invention also proposes a timepiece provided with such a display member (10). The invention also proposes a method of fabricating analogue display members (10) to be fitted to timepieces, each analogue display member (10) including a main body, characterized in that it includes at least one step of micro-machining a wafer of silicon based crystalline material to form at least one main body in said material.
A method of fabricating analogue display members to be fitted to timepieces, each analogue display member including a main body in which an arbor hole is arranged, the arbor hole being fitted to a drive arbor, wherein said method includes at least one step of micro-machining a wafer of silicon based crystalline material to make at least one main body in said crystalline material with said arbor hole and wherein, during the wafer micro-machining step, flexible elements are formed on the main body to allow assembly of the analogue display member on the drive arbor via the resilient deformation of the flexible elements.
An analogue display member fitted to a timepiece, including a main body in which an arbor hole is made, said arbor hole being fitted to a drive arbor, wherein the main body is made of a silicon based crystalline material and wherein said arbor hole is provided with flexible elements that are made in a single piece with the main body in order to exert a gripping force on said drive arbor.
