For timing successive events while ignoring the intervals between them.
Each result accumulates. For example: timing the stages of a car rally:
1) At the start of the first stage, press button A to start the chronograph.
2) At the end of the first stage, press button A again to stop the chrono-
graph.
Repeat the process for each stage. At the end of the final stage the
chronograph will show the total rally time.
Press button B to zero the chronograph.
3. Split- / Intermediate-time function
For timing a single event while registering intermediary times.
1) Press button A to start the chronograph e.g. for a running race.
2) Press button B to register an intermediary time. The chronograph
meanwhile continues to time the race.
3) Press button B again. The chronograph hands catch up with the time
elapsed since the start of the race.
4) Repeat the process, pressing button B to record an intermediate
time and pressing it again to show the elapsed time of the race.
