to the previous one.
 Press button A: the chronograph starts.

Repeat these two steps as many times as desired. At the
end of the last measurement, the chronograph displays
the total of all the times measured. Press button B to
reset to zero.
Split-time function (intermediate times)
This function allows the display and reading of mul-
tiple successive times measured from the same start-

caught up on without disturbing the measurement of
total elapsed time.
 Press button A: the chronograph starts.
. Press button B to read the rst intermediate time.
 Press button B again. The chronograph hands catch
up with the time elapsed since the beginning of the

mediate time, and once again to cause the hands to
catch up.
 At the end of the whole measurement, press button
A to read the total time.
 Press button B to reset to zero.
NB: The maximum catch-up time is  minutes.
