IMPORTANT! The time, or any other display, should not be adjusted
while the chronograph function is being used.
Important notes
a) It is possible to combine the various Chrono functions (SIMPLE,
ADD and SPLIT) in the same timing operation.
b) Unless the chronograph is stopped (STOP pressed), the chro-
nograph hands will not stop moving. Continuous running of the
chronograph
will greatly reduce the autonomy of the movement.
Battery end-of-life mode (E.O.L)
If the battery voltage decreases and the risk of function loss arises,
E.O.L mode is activated. If the voltage is below the E.O.L level,
the chronograph functions are locked, and the small seconds at
6o'clock is stopped.
E.O.L mode is activated if the battery voltage is below the E.O.L level
for more than one hour. If the battery voltage climbs above the E.O.L
level for more than 15 minutes, E.O.L mode is deactivated. This
scenario may occur in particular if the watch has been temporarily
exposed to low temperatures.
In this mode:
The small seconds hand moves jerkily. The hand moves 4 steps
quickly, and then remains immobile for 4 seconds.
The chronograph can no longer be activated (START) for approxi-
mately one hour after E.O.L mode has been activated.
If the chronograph was active at this time, it will continue to run,
though there could be step loss.
