  • the component 1 is produced with at least one such surface of appearance 2 bordered by a projecting edge 9, and during the diamonding, this protruding edge 9 which delimits the surface of the surface is produced. aspect 2.
  • all the appearance surfaces 2 intended to remain visible are diamond-coated, removing at least part of the excess thickness 5 that the thick layer 4 second material, and when the component 1 has it, diamante all the protruding edges 9 which define these surfaces of aspect 2.
  • At least one surface of appearance 2 is dotted so as to remain visible, by removing part of the thick layer 4 from the second material, with a state of area between 2 nm Ra and 100 nm Ra.
  • a residual thickness ER greater than or equal to 5 micrometers, of the thick layer 4 of the second material, is maintained at each aspect surface 2 .
  • a galvanic or PVD or CVD or ALD coloring operation is carried out with a thickness of less than 5 micrometers, at least two aspect surfaces intended to remain visible, after the operation of FIG. diamantage.
  • the first material is selected from alloys of copper and / or aluminum and / or zinc.
  • a brass is chosen for the first material.
  • the first material is chosen from an aluminum alloy.
  • a zinc alloy is chosen for the first material.

  • nickel-phosphorus is chosen for the second material.
  • the blank 3 is covered with the thick layer 4 of the second material by chemical deposition in bulk.
  • the blank 3 is covered with the thick layer 4 of the second material by galvanic deposition.
  • the billet 3 is produced by deformation or stamping or stamping.
  • the hollow billet 3 is produced and / or comprising at least one attachment foot 10.
  • a hollow component 1, with a cavity 70 is advantageous in terms of mass and economy of materials, in particular when the component 1 is a needle 11, represented here with a barrel 110, the unbalance thus being minimized .
  • the display or switching component 1 is produced in the form of a needle 11 or a wall 12 or a numeral 13 or a symbol 14 or a monogram 15 or an indicator 16 or an index 17 or an entourage of a window 18.
  • One embodiment using the invention relates to a watch 100 comprising at least one component 1 display or switching made by this method.
  • the diamond finish state of such a component is distinguished by the perfect quality of the surface condition (mirror) and the intersection of the faces that define sharp edges, that no other method of manufacture can provide.
