A chronograph system comprising a display system , the display system allowing the display of a measured time, the system comprising: - a limb comprising at least one modifiable graphic element (20a-f) forming a reference measured time, - a measured time indication member in cooperation with the limb, - a device for modifying the graphic element, and - a device for resetting, by action of a user, to a predetermined configuration the measured time displayed by cooperation of the indication member and of the limb, the at least one modifiable graphic element being arranged such that, in several configurations of the at least one modifiable graphic element, the at least one modifiable graphic element defines or help to define several complementary ranges of a value scale of measured time, the display system comprising a display of the jumping type of the at least one graphic element (20a-f) forming the reference measured time, the display system being configurable in a first configuration (C1) and in a second configuration (C2), the chronograph system being arranged such that: - a switch from the first configuration (C1) to the second configuration (C2) of the display system occurs after the indication member has traveled over the entire length of the limb , - a switch from the second configuration (C2) back to the first configuration (C1) of the display system occurs after the indication member has once again traveled over the entire length of the limb, the device for modifying the graphic element comprising an energy accumulator and a mechanism for transmitting energy to the accumulator kinematically connected to the indication member . - a limb comprising at least one modifiable graphic element (20a-f) forming a reference measured time, - a measured time indication member in cooperation with the limb, - a device for modifying the graphic element, and - a device for resetting, by action of a user, to a predetermined configuration the measured time displayed by cooperation of the indication member and of the limb, the at least one modifiable graphic element being arranged such that, in several configurations of the at least one modifiable graphic element, the at least one modifiable graphic element defines or help to define several complementary ranges of a value scale of measured time, the display system comprising a display of the jumping type of the at least one graphic element (20a-f) forming the reference measured time, the display system being configurable in a first configuration (C1) and in a second configuration (C2), the chronograph system being arranged such that: - a switch from the first configuration (C1) to the second configuration (C2) of the display system occurs after the indication member has traveled over the entire length of the limb , - a switch from the second configuration (C2) back to the first configuration (C1) of the display system occurs after the indication member has once again traveled over the entire length of the limb, - a switch from the first configuration (C1) to the second configuration (C2) of the display system occurs after the indication member has traveled over the entire length of the limb , - a switch from the second configuration (C2) back to the first configuration (C1) of the display system occurs after the indication member has once again traveled over the entire length of the limb, the device for modifying the graphic element comprising an energy accumulator and a mechanism for transmitting energy to the accumulator kinematically connected to the indication member . <EOS>
