12. USE OF THE ROTATING BEZEL
Some watches are not equipped with a bezel, depending on the model.
1.
Tachymeter (non-rotating bezel type).
2.
Directional (rotating bezel type).
If your watch is provided with a tachymeter: The
tachymeter is a feature that measures the speed of
an automobile. Measuring how many seconds a car
travels over a distance of 1km enables the tacymeter
scale to show the approximate average speed per
hour during a journey (if this 1km is covered within a
maximum of 60 seconds.) If the chronograph is started
at the beginning of the distance measurement, and
stopped after 1km, the average speed per hour can be
determined by the position of the chronograph second
hand. If 1km is covered in 45 seconds, the average
speed will be about 80km/h.
1.
Tachymeter
If your watch is provided with a compass bezel:
The compass feature on this watch isbased on the
position of the sun. This compass should only be
used as an approximate direction finder. Changes
in latitude and the seasons may also cause
directional misreadings.
One of the feaures of this watch is a directional
rotating bezel for use in the Northern Hemisphere.
By aligning the hour hand with the position of the
sun in the sky, the point halfway between this
position and 12
O’ clock will be South. Align the ‘’S’’ mark on
the rotating bezel with this halfway point to
determine all other points of the compass.
