Mechanical digital display including at least one digit consisting of at least seven segments (1) for the display of alphanumeric characters. Each segment (1) is a body in the form of a bar (1) which can pivot about its longitudinal shaft (3), the said bars (1) having at least two areas resembling a first and a second strip (1′, 1″). These have different appearances, and are arranged along the length of the bar (1) in such a way that the orientation of the bar (1) by rotation about its longitudinal shaft (3) enables either the first or the second strip (1′, 1″) to be made visible. The display of an alphanumeric character is achieved as a result of the dissimilarity of the appearance between the first and second strip (1′, 1″) of the set of bars (1). The pivoting of one or more bars (1) to replace the first strip (1′) with the second strip (1″) or vice versa generates the display of different alphanumeric characters. At least one pinion (2), fixed to the bar (1), is positioned around each longitudinal shaft (3) adjacent to at least one of the ends of said bar (1). The bars (1) are pivoted by means of cams (4) interacting directly or indirectly with each pinion (2).
