Abstract (en)
[origin: EP1024416A2] The device includes blocking elements isolating and locking the display during reading of detailed timings. The chronograph comprises a secondary display (16,17) which shows fractions of a section. This co-operates with an operating mechanism (20) comprising a 'snail' gear (21) driven by a chronograph mechanism (4). A push rod (19) acts on the activating elements (40,46) to release a main pivoting element (30) which changes fraction of a second measuring on the snail gear, by means of a drive train (33). A first blocking device (58) allows the isolation of the striker (54) of the chronograph to prevent a return to zero during the reading of a fraction of a second. A second blocking device (59) inhibits a re-start of the chronograph during this reading, and prevents a re-starting of the activating mechanism (20) during the operation of the chronograph. A third element (66) blocks the snail gear during the reading of the fraction of a second.
