Chronograph seconds hand: The scale for the central chronograph seconds hand
runs around the edge of the dial.
Minute and hour counters: The subdial at 12 o’clock has two hands, which run
continuously and show the elapsed time on a 12-hour and a 60-minute scale. The
hour and minute counters can be read like a standard analogue time display. In other
words, one revolution of the minute counter is equal to 60 minutes, and one revolution
of the hour counter is equal to 12 hours.

Start:
To start the chronograph, press the start/stop button.
Flyback:
You can start recording a new time immediately, even when the chrono-

as far as it will go.
All three chronograph hands are reset to zero, and a new measurement is started as
soon as the button is released.
Stop:
To stop the running chronograph, press the start/stop button.
Reset:
Depress the reset/flyback button fully,
as far as it will go.
This will reset all
the chronograph hands to zero.
Aggregate time recording:
You can add stop times together by pressing the start/
stop button again after the first measurement, instead of the reset/flyback button.
