A chronograph watch with an analog display (point-
er-type indication of the hours, minutes and seconds) is
an instrument capable of measuring time.
The Flyback function serves to stop, reset and restart the
chronograph in a single operation (instead of three as on
a classic chronograph).
Retrograde displays are distinguished by a hand
describing the arc of a circle (instead of spinning around
an axis) and which returns to its initial position once it
reaches the end of its trajectory.
The annual calendar is a complication that serves to
display the exact date during every 30- and 31-day month.
A single annual correction is required, in February.
The power reserve enables one to visualise the
remaining time during which a mechanical movement
will continue to run.
