The first indicator member is pierced with second openings, said second openings being arranged to stop directly underneath one of said first openings during the step-by-step rotation of the first indicator member. The display mechanism includes a second indicator member at least partially superposed on the first indicator member in the display area. The second indicator member bears a pattern comprising segments. ## Claims ### Claim 1 A character display mechanism for a timepiece including a first indicator member disposed underneath a mask and arranged to rotate in steps about an axis, the first indicator member bearing a series of intertwined figures distributed over a circular track, the mask including a display area having a plurality of first openings, the figures being intended to appear successively through the first openings during the rotation of the first indicator member, and the first openings being disposed such that only one figure at a time appears in the display area; wherein the first indicator member is pierced with second openings, said second openings being arranged to stop directly underneath one of said first openings during the step-by-step rotation of the first indicator member, wherein the display mechanism includes a second indicator member disposed underneath the mask and arranged to rotate in steps about an axis parallel to the axis of rotation of the first indicator member, the first indicator member and the second indicator member being at least partially superposed and the first indicator member extending between the mask and the second indicator member in the display area; wherein the second indicator member bears a pattern including segments, one of said segments and one of said second openings being arranged to stop together directly underneath one of said first openings, so that said segment appears in the display area in combination with the figure visible at that moment, so as to form a character to be displayed. ### Claim 2 (depends on 1) The character display mechanism according to claim 1, wherein the mechanism is arranged to display different indications using same set of segments, the superposition of a set of indications to be displayed corresponding to the display of the complete set of segments. ### Claim 3 (depends on 2) The character display mechanism according to claim 2, wherein all the segments are line segments. ### Claim 4 (depends on 3) The character display mechanism according to claim 3, wherein the segments borne by the second indicator member are intertwined, and wherein one of the second openings has the shape of a segment. ### Claim 5 (depends on 3) The character display mechanism according to claim 3, wherein the mechanism is arranged to display the various indications using a standard set of seven segments or with a set of nine segments formed by a set of seven segments, for displaying a units number using the set of seven segments, in combination with two additional segments for displaying the numeral 1 before the units number. ### Claim 6 (depends on 5) The character display mechanism according to claim 5, wherein the various segments of the standard set of seven segments or of the set of nine segments are each oriented in one of two orientations (respectively horizontal and vertical) which are perpendicular to each other. ### Claim 7 (depends on 6) The character display mechanism according to claim 6, wherein the first indicator member is arranged to make eight steps per revolution about its axis, and wherein the series of intertwined figures borne by the first indicator member is formed of eight figures. ### Claim 8 (depends on 7) The character display mechanism according to claim 7, wherein the horizontally oriented segments and the vertically oriented segments have the same length, and wherein the intertwined figures intersect each other at the ends of the segments. ### Claim 9 (depends on 1) The character display mechanism according to claim 1, wherein the figures borne by the first indicator are presented in a first colour on a background of a second colour, with the colour of the mask being the second colour.
