 HOW TO USE THE INTERNAL ROTATING INDICATOR RING
Please notice that some models come with an internal rotating indicator ring,
which should be used properly.
Turn the crown for the internal rotating indicator ring to set the - mark to
the position of the minute hand.
The position of the internal rotating indicator ring to which the minute hand is
pointing after some time has elapsed indicates the elapsed time.
Setting the mark to the desired time also allows you to know the remaining
time.
