10. Zero Positioning of Chronograph
Second Hand
When resetting the chronograph, if the chronograph second hand does not
return to the 0 seconds position or if the chronograph second had has shifted
out of position due to strong impact, perform zero positioning of the
chronograph second hand according to the procedure described below.
• In the case the crown is of the screw-lock type, loosen the screw before
operating the crown.
• The zero positioning procedure cannot be performed while the insufficient
charging warning feature is activated (while the second hand is moving at 2-
second interval movement due to the watch being insufficiently charged).
Sufficiently charge the watch and check that the second hand is moving at 1-
second interval movement before performing the zero positioning procedure.
