Abstract: A method of fabrication of a wristband of a watch or piece of jewelry, including: providing a first synthetic material; providing an extrusion line with a die plate for making an extrudate from the first material; providing one or more additional materials distinguished in their properties from the first material; providing a die plate including a first zone defining a profile allowing for fabrication of an extrudate having a hollow tubular profile at least at one of its ends in which the extrudate has a width corresponding to the length of one or two strands of the wristband; the die plate further includes a second zone allowing defining of particular profiles selected from among a flat profile, a curved profile, or a profile with projecting zones.
