Abstract (en)

[origin: EP2508953A2] The mechanism has a chronograph gear train comprising a seconds-counter mobile (1) and a mobile (3) with first precision corresponding to first fraction e.g. tenth, of a second. The gear train has an additional mobile (5) with second precision corresponding to second fraction e.g. hundredth, of second, where the additional mobile is driven by the mobile for the first fraction of second via a backlash compensating mobile (4). An indicator, actuated by the additional mobile, indicates the second fraction of second of measured duration, smaller than the first fraction of second.
