Device enabling a timepiece movement to display the time in a predefined time zone

A timepiece movement comprising a display device including an hour display wheel intended to carry an hour display organ for a predefined time zone, and to be specifically driven by a drive wheel of the timepiece movement,

• a chassis intended to be rotated about a first main axis and to cooperate with indications that are static in relation to a frame of the timepiece movement in order to display information,
• a moveable organ mounted rotatably on said chassis about a second rotation axis distinct from said first main axis,
• a correction mechanism arranged so as to be able to drive said moveable organ to a predefined angular position in relation to the frame of the timepiece movement, regardless of the angular position of said chassis about said first main axis,
• wherein the respective angular positions of said chassis and of said hour display wheel are indexed in relation to each other in such a way that the angular position of said chassis about said first main axis is intended to be associated with the display of static information relating to said predefined time zone, and
• the display device further comprising a selection mechanism arranged:
• —to rotate said hour display wheel, in response to a predefined action by a user, such that said hour display wheel moves from a first position associated with the hour display in a first time zone to a second position associated with the hour display in a second time zone, and
• to simultaneously rotate said chassis in steps so that said chassis moves from a first position, associated with the display of information relating to said first time zone, to a second position, associated with the display of information relating to said second time zone.
