An essential feature of all Alpina diving watches is the
unidirectional, anti-clockwise, rotating bezel, used
to control immersion time. The bezel is fitted with a
graduated scale divided into minutes. The bezel’s
working principle is both simple and reliable. At the
beginning of each immersion, the zero on the bezel
must be aligned with the minute hand. A simple
glance at the position of the minute hand with respect
to the bezel will show the diver at any moment how
much time has elapsed since the start of the dive (in
minutes). The unidirectional anti-clockwise rotation
of the bezel is a safety feature that ensures that any
accidental movement of the ring will always cause the
remaining diving time to reduce with respect to the
effective remaining diving time. An essential feature of all Alpina diving watches
is the bidirectional rotating bezel, used to control
immersion time. The bezel is fitted with a graduated
scale divided into minutes. The bezel’s working
principle is both simple and reliable. At the beginning
of each immersion, the zero on the bezel must be
aligned with the minute hand. A simple glance at the
position of the minute hand with respect to the bezel
will show the diver at any moment how much time
has elapsed since the start of the dive (in minutes).
Our watch is equipped with a screw-down crown so
the bidirectional internal bezel cannot move unless the
crown is unscrewed. This is a safety feature to avoid
any accidental movement of the bidirectional internal
bezel that could make the diving time incorrect.

TACHYMETER SCALE USE
Example 1: calculating the speed of a car.
Measure the time it takes the car to cover a distance of
1 km. Read off the speed indicated by the central chro-
nograph seconds hand on the tachymetric scale. In our
example, the car is travelling at 90 km/h.
Measurement scales are scales that establish a relation
between elapsed time and another variable. The
desired information in terms of speed (tachymeter),
distance (telemeter) or units (pulsometer, productivity
meters) is read off between the central seconds hand
of the chronograph and the corresponding scale, over
a maximum duration of 60 seconds. For the telemeter,
it is possible to make use of the minutes counter by
adding 20 km to the distance indicated by the central
seconds hand for each minute elapsed.
