Instruments of time.
86 saw the dawn of a new era in German watch manu -
facturing, with the visionary and entrepreneur Erhard
Junghans. Today, for the Erhard Junghans brand ”Made in
Germany“ once again stands for timekeeping instruments
of the utmost precision and value-adding functionality
with a classic, design-oriented style.
With pioneering spirit and creative energy Erhard
Junghans breathed new life into traditional values, in the
process leaving a permanent impression on the course of
time.
Today, as was the case in those days, Schramberg has
witnessed the coming together of individuals to produce
the exceptional – just as Erhard Junghans did in his era.
The same intention. A new beginning.

General instructions for use
Win ing the watch
Your Erhard Junghans Aerious is equipped with a screwed-in crown. In
the home setting (crown in position A) the crown is screwed in. By turn-
ing it to the left you get to the position for winding the watch (crown in
position B). If you can feel that the crown will turn freely, you can wind
up the automatic movement by hand. 2-3 turns of the crown suffice to
set the movement in motion. It is better to wind the watch completely,
as this guarantees maximum accuracy and power reserve (including
after removal of the watch). The watch should be worn after winding in
order for the automatic winding mechanism to maintain a fully-wound
state (via the rotor movement).
Setting the ate
Pull the crown to Position C (fast adjustment). The date can be altered by
turning the crown to the right. Rotate the crown until the date of the pre-
vious day is displayed. (The actual date is then adjusted with the setting
of the time).
Important: Date alteration should not be performed between 8 PM and
3 AM, as in this period the date is switched automatically by the move-
ment and damage may be caused to the switching mechanism.
If the month has less than 3 days, the date must be forwarded to the st
of the following month by hand.
Setting the time
Pull the crown to Position D. This stops the movement.
To set the watch accurately to the second it helps to stop the movement
when the second hand is over the 60. Now turn the crown to the left. As
soon as the hour hand passes midnight the date is switched to the cur-
rent date. Turning the crown further enables the precise time to be set,
accurate to the minute marker. Return the crown to Position B to start the
second hand.
Note:
After winding up and setting your watch you must always screw the
crown back into place. Only with the crown screwed in can the watch’s
waterproof level of 0 ATM be assured. To screw the crown in, press it
gently and at the same time turn it to the right until it locks firmly into
place.

General information
Water resistance
Your Erhard Junghans watch has been tested for water resistance to a
pressure of 0 ATM. This test indicates that your watch is suitable for
wearing in the shower, when swimming and also snorkelling. It should
not be worn when diving. The 0 ATM water resistance status applies to
factory-new watches only. External influences, such as damage to the
crown, pushers and glass, may affect water resistance. It is therefore
important that you have your watch examined. If moisture has entered
the watch, this must be investigated by customer service without delay.
Water entering the watch may result in damage. We therefore recom-
mend that you contact an Erhard Junghans specialist retailer.
Strap
Your Erhard Junghans watch is equipped with a high quality wrist strap,
which has been tested extensively at our company. It should be noted
that leather straps are not suitable for wearing in water and should not
be subjected to strong UV rays. Please use an original strap if you choose
to replace your strap.
