Reading the chronograph 18 | 19
Chronograph seconds hand: The scale for the central chronograph sec-
onds hand runs around the edge of the dial.
Minute and hour counters: The subdial at 12 has two hands, which run con-
tinuously 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 dis-
play. In other words, one revolution of the minute counter is equal to 60 min-
utes, and one revolution of the hour counter is equal to 12 hours.
Using the chronograph
Start: To start the chronograph, press the start/stop button.
Flyback: You can start recording a new time immediately, even when the
chronograph is running. With the chronograph running, simply depress the
reset/flyback 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 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.
