Abstract
A process for blanking an applique for a watch dial, comprises a step of blanking with a laser beam a first part of the outline of this applique, defining a pointed zone or/and a thin groove of at least a first hollow or/and the point or/and the drawn-out portion of at least a first projecting part, and a step of blanking by means of a stamp a second part of said outline which is complementary with the first part. This hybrid blanking technology makes it possible to obtain appliques having, at the end of the blanking process according to the invention, an outline which defines at least one hollow having a pointed zone or/and a thin groove or/and which defines at least one projecting part forming a point or/and a drawn-out portion with configurations and particular dimensions that cannot be obtained by blanking merely by stamping.
