  • the index item can be hunted on the index body.
  • the first pull tab position corresponds to a position of the first stem in which the stem is the most depressed in the movement.
  • the second pull-tab position corresponds to the first indexed and stable position of the first rod that is encountered when a pulling action is exerted on the first rod when it is in the first position.
  • the third pull-tab position corresponds to the first indexed and stable position of the first rod that is encountered when a pulling action is exerted on the first rod when it is in the second position.
  • the invention also relates to a method for mounting a pull tab indexing device 100, 100' as described previously or to a method for mounting a mechanism 600 as described previously or to a method for mounting a movement 700 as described above or on a method of assembling a timepiece as described above.
  • the indexing element can alternatively be mounted on the indexing body in a third position.
  • a pull tab indexing element can be chosen and configured upstream of the assembly of the timepiece movement, so that the pull-cord device can position the stem of the mechanism in which it takes part according in particular to two or three positions. Thanks to these solutions, in which a pull-bar indexing element can be chosen and configured upstream of the assembly of the timepiece movement, the risk that a watchmaker may make an assembly error when assembly of the movement in which the mechanism takes part, or during a repair operation, is cancelled.
  • the solutions described make it possible to produce a configurable pull-cord device, which in particular makes it possible to implement a mechanism with two or three positions depending on the number of functions to be corrected. These solutions make it possible to maximize the number of components and assemblies common to the movements of the same family.
  • indexing body preferably means a body supporting an indexing element, in particular a body supporting an indexing cam.
