Using the telemetric scale
Example: calculate the distance between
your position and an event producing
light and sound simultaneously (e.g.
a storm).
The chronograph is set off by the detec-
tion of light, for example a lightning
strike. Then it stops on detection of the
sound, the clap of thunder. Here, the
storm is 9.9 km away.

Reading the chronograph minute counter
(Seamaster Diver 300M, ETNZ 2015)
Example: counting down the time before
the start of a regatta.
3H counter:
The inside timer displays the minutes of
the chronograph using the white part
of the Regatta needle.
The outside timer displays the 5-minute
countdown before the start of the regatta.
The chronograph is started at the first
horn blast, 5 minutes before the start of
the regatta, to allow the yachtsman to
position his boat closer to the starting
line.

Reading the chronograph minute counter
(Seamaster Diver 300M, 36th America's Cup)
Example: counting down the time before
the start of a regatta.
3H counter:
The counter has a minute hand and
an hour window. The white part of the
indicator represents the 10-minute
countdown to the start of the regatta.
The pre-regatta phase is divided into 2
parts, the first 5 minutes are allocated
to preparing the boat and crew and the
other 5 minutes to the positioning of the
boat.
The chronograph is started at the first
signal, 10 minutes before the start of
the regatta.
