Beschreibung
Zusammenfassung:	A timepiece hand and method for manufacturing same, including: obtaining a single-piece part, the part extending along a longitudinal axis; rotating the single-piece part; emitting a first modulation of the laser light; exposing a first portion of the single-piece part to the first modulation of the laser light to form a first volume with a circular cross-section with a length L1 and with a mean diameter D1, the ratioL1D1being less than or equal to 20 or 10; emitting a second modulation of the laser light; and exposing a second portion of the single-piece part to the second modulation of the laser light, to form a second volume with a circular cross-section with a length L2 and with a mean diameter D2, the ratioL2D2being less than or equal to 10.
