The method for manufacturing the one-piece mechanical timepiece part by laser light includes the steps of providing a one-piece material part, oscillating and/or rotating the rotary element and forming the one-piece mechanical timepiece part by power and time modulation of the laser light.

Packaging (1) for clock hands (2) with a pipe (4) and a body (5), including a pallet (10) for receiving, holding, storing and carrying hands (2) having the same height, including bores (11) for receiving the pipes (4) according to a constant pitch, adjacent to recesses (12) for housing the hand bodies (5) resting on an upper surface (13), each pallet (10) including a position index device (20), and a spacer (15) for cooperating such that it bears against a lower surface (14) of another pallet (10) and extending, from the upper surface (13), over a height which exceeds that of the hand bodies (5), each pallet (10) having a transverse bearing surface (130) for receiving the bearing surfaces (3) of the hands (2), and, parallel thereto, oblong pieces (131), the width whereof is adapted for the insertion of robotic grippers or tweezers for loading/unloading hands.

A watch component is formed of a metal member formed into a component shape. A surface of the metal member includes a coated region being coated with a coating material having a color different from a material color of the metal member and an exposed region from which the material color of the metal member is exposed. A boundary part between the coated region and the exposed region forms a blade-pattern-like design.
