Abstract
Official abstract text for this publication.
The chronograph mechanism includes a control device and a chronograph gear train designed to be driven directly or indirectly by a barrel, this chronograph gear train including a second-counter mobile and a mobile with a first precision corresponding to a first fraction of a second. The chronograph mechanism also includes at least one indicator which displays the seconds and first fractions of a second of the duration measured. The chronograph gear train includes an additional mobile ( 5 ) with a second precision corresponding to a second fraction of a second, which is driven by the mobile ( 3 ) for the first fraction of a second by a mobile ( 4 ) compensating the backlash; and the chronograph mechanism also includes an indicator for the second fractions of a second, which are smaller than the first fractions of a second, of the duration measured, which indicator is actuated by the additional train.
First claim
Opening claim text (preview).
The invention claimed is: 1. A chronograph mechanism comprising: a control device; a chronograph gear train configured to be driven directly or indirectly by a barrel and regulated by a regulator unit, the chronograph gear train comprising a second-counter mobile and a mobile with a first precision corresponding to a first fraction of a second, and the regulator unit oscillating at a frequency corresponding to the first precision; and at least one indicator which displays the…
