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-
button.

Setting when crossing time zones:
– When crossing time zones in an easterly direction, you should simply set the time
forwards to the new local time.
– When crossing time zones in a westerly direction, you can set the hands of your
watch back to the actual time of day. When doing this, however, you must not
move back into the calendar's automatic switching phase, i.e. beyond 2 a.m. If this
situation occurs when you are travelling west, you should set the local time of your
destination before 8 p.m. You must not turn the hands back between 8 p.m. and
2 a.m. This is because the calendar does not move backwards by one day when
