Abstract (en)

[origin: WO2023012036A1] Disclosed is a method for manufacturing a timepiece component, the method being characterised in that it includes the following steps: –Ÿ providing (E1) a substrate (20) comprising an upper surface (21); Ÿ–Ÿ applying (E2) an anti-glare treatment to all or part of the upper surface (21) of the substrate (20); –ŸŸ depositing (E31) a layer of photoresist (40) on the upper surface of the substrate (20); –ŸŸ exposing (E32) said photoresist (40) to exposure radiation (45) according to a predetermined pattern; –ŸŸ and developing (E33) the photoresist (40), so as to form a mould delimited at least partially by said photoresist (40) and by a portion of said at least one upper surface (21) of the substrate (20).
