Abstract
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.
