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 push-button.
Flyback: You can start recording a new time immediately, even when the chronograph
is running. Simply depress the reset/flyback push-button fully as far as it will go. All
three chronograph hands are reset to zero, and a new measurement is started as soon
as the push-button is released.
Stop: To stop the running chronograph, press the start/stop push-button.
Reset: Depress the reset/flyback push-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
push-button again after the first measurement instead of the reset/flyback push-but-
ton.
