NORMAL POSITION

With the crown in the normal position
(0), you can also wind the automatic
movement by hand. A few revolu­
tions of the crown are enough to start
the movement. However, it is recom­
mended to wind the watch by turn­
ing the crown through approximately
20 revolutions, as this will ensure opti­
mal precision. The crown must always
be in position 0 when you are wearing

your watch.
