1. A timepiece mechanism (100) comprising:
an ambient physical variable measuring device (5) comprising an element configured to mechanically deform under the effect of a variation of said physical variable;
a physical variable measured value indication train (10) kinematically linked to the physical variable measuring device, in such a way as to be rotated under the effect of a variation of the ambient value of the physical variable;
a physical variable maximum value indication mechanism (20) comprising a physical variable maximum value display train (24) comprising a physical variable maximum value display wheel (21), said physical variable maximum value indication mechanism (20) comprising a physical variable maximum value indicator organ (23) integral with the physical variable maximum value display wheel (21);
a drive mechanism (30) configured to gradually drive the physical variable maximum value display train (24) during an increase of the ambient physical variable;
an indexing mechanism (40) to index the position of the physical variable maximum value display train (24) at each advance, the indexing mechanism (40) comprising a blocking organ (41) contacting and cooperating with an indexing wheel assembly (43);
wherein the indexing wheel assembly (43) is kinematically connected to the physical variable maximum value display wheel (21) by a gear train and in that the gear ratio of the gear train between the physical variable maximum value display wheel (21) and the indexing wheel assembly (43) is a multiplication ratio.
