4.3 “Regatta” function with flyback
4.3.1 First warning signal
Eleven minutes before the official crossing of the start / finish
line, start the chronograph using the pushpiece at 2 o’clock (C).
Simultaneously, chronograph hand 4, the red “regatta” hand 5
and counters (7 and 8) will start.
4.3.2 Second warning signal (flyback function)
Ten minutes before the official crossing of the start / finish line,
press the pushpiece at 4 o’clock (D) and activate the flyback
function. This immediately zeroes all chronograph functions
and the chronograph instantly starts again. This is the signal that
tells crews they only have ten minutes until the start of the race,
to stow the sail and other equipment. The final details about the
weather conditions can also be discussed with the base.
