JUNGHANS – THE GERMAN WATCH
Many congratulations on your purchase of a timepiece from
Junghans.
What began in 1861 with the founding of the rm in Schramberg
quickly developed into one of the most fascinating success stories
of the German watchmaking industry. While since that time the
demands made of watches may have changed, the Junghans
philosophy has always remained the same. Innovative air and
the constant pursuit of precision right down to the smallest
detail dene how the company works and thinks. You can see and
sense this in every watch that carries the Junghans name. For as
diverse as the Junghans range may be, it pursues one single goal:
to combine traditional craftsmanship with cutting-edge watch
technology and exciting design. That makes every watch with the
Junghans star unique.
We hope you will enjoy this very special time-keeping instrument.
Yours,
Uhrenfabrik Junghans GmbH & Co. KG

1. Environmentally friendly solar technology
Technology that requires no battery! Light – whether sunlight or
articial – permeates the solar dial or the light transparent dial. This
transforms the light into electrical energy, which is then stored in a
long-lasting energy store. The energy store serves as an energy source
for the solar wristwatch and enables the watch to function – even in
complete darkness.

Setting the date
Pull the crown into position B. Rotate the crown to the right to set
the date. Date alteration should not be performed between 20 PM
and 2 AM, as in this period the date is switched automatically by the
movement and damage may be caused to the switching mechanism.
If the month has less than 31 days, the date must be forwarded to the
1st of the following month by hand.
2.2 Charging control display
To ensure that your Junghans solar wristwatch is always ready for use
you should ensure that it is not lacking energy. The watch checks the
charging status of the energy store at regular intervals. If this reveals
insucient energy, the second hand begins to move in 2-second
stages. In this case you should recharge the watch as soon as possible.
Setting the time
Pull the crown to position C. 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. You can now position the minute hand
on the minute marker and set the required time. Return the crown to
position A to start the second hand.

the 1st of the following month by hand.
3.3 Charging control display
To ensure that your Junghans alarm chronoscope is always ready for
use you should ensure that it is not lacking energy. The watch checks
the charging status of the energy store at regular intervals. If this
reveals insucient energy, the second hand (4) begins to move in
2-second stages. During this time the chronoscope and alarm function
is deactivated. You should therefore recharge the watch as soon as
possible.
If the watch is operated at low energy levels for a longer period of time
or stored with empty energy levels, to ensure secure functioning please
conduct a reset (3.7) before setting the alignment of the counters to
the zero position (3.8).

3.7 Resetting the calibre J622.50
Following complete discharge of the energy store it is advisable to
conduct a reset. To do this, pull the crown to position C. Ensure that
the crown is not locked. Operate the start-stop pusher (7) and the reset
pusher (11) simultaneously for at least 2 seconds. Now push the crown
back into position A. The reset is completed, now set the correct time
and date (10).
3.8 Setting the counters to the zero position
If one or more of the chronoscope counters are not in the correct
position (e. g. following complete discharge of the energy store), these
should be set: pull the crown into position C.
Alarm hands
Ensure that the crown is not locked. Now operate the reset pusher (11)
to adjust the alarm hands (5). Operate the reset pusher (11) briey for a
single step and longer for continuous setting, until the alarm hands (5)
display the current time. If the adjustment is activated with the alarm
activated but not triggered, the alarm hands (5) will rst move to the
current time.
Stop minute hand
To adjust the stop minute hand (2) operate the start-stop pusher (7) for
2 seconds. The hand (2) rotates one full rotation and stops at the start
position. Now operate the reset pusher (11) to adjust the stop minute
hand (2), a short push for minute steps, a longer push for continuous
adjustment.
Measuring split times
During the time measurement process it is possible to display a split
time without stopping the stopwatch process. To do this, start measu-
rement using the start-stop pusher (7). To read the split time operate
the reset pusher (11). The time measurement continues in the backg-
round. Pressing the reset pusher (11) again results in the chronoscope
counter advancing rapidly to catch up with the time that has elapsed.
Stop the chronoscope function by pressing the start-stop pusher (7)
again. To return the chronoscope hands to the zero position, press the
reset pusher (11).
3.6 Alarm
To use the alarm function it is necessary for the alarm display (5) to also
display the current time, i.e. please set the current time before setting
the required alarm time. Pull the crown to position B. Now press the
reset pusher (11) briey for a single movement and longer for a con-
tinuous adjustment, until the current time is displayed in the alarm
display (5). Move the crown back to position A.
To set the alarm time, move the crown back to position B. Use the
reset pusher (11) to set the required alarm time (5). To start the alarm,
push the crown back to position A. When the alarm time is reached
an acoustic signal will sound for 20 seconds, or until a pusher (7 / 11) is
operated. After the alarm has sounded it is no longer active, the current
time is displayed until the next activation. If a further alarm is required,
please set this as described above, via the reset pusher (11).

4. Information for watches with tachymeter scale
Reading the tachymeter scale
The scale is based on a stretch of one kilometre. At the beginning of
the stretch the stopwatch function is activated and the time lapsed
stopped after one kilometre. The second hand displays the average
speed travelled on the scale.
An example: you are travelling along
the motorway as a PASSENGER in a
car. The reector posts have a spac-
ing of 50 m. You begin the stop-
watch operation at the rst reector
post and end the process on the
twenty rst. You have consequently
travelled one kilometre. The second
hand now shows you the average
speed. If you require 30 seconds for
one kilometre, your average speed
is 120 km/h.
Stop minute hand
To adjust the stop minute hand (2) operate the start-stop pusher (7) for
2 seconds. The hand (2) rotates one full rotation and stops at the start
position. Now operate the reset pusher (11) to adjust the stop minute
hand (2), a short push for minute steps, a longer push for continuous
adjustment.
To adjust the stop minute hand (2) operate the start-stop pusher (7)
again for 2 seconds. The hand (1) rotates one full rotation and stops at
the start position.
1/5 Stop second hand
Now operate the reset pusher (11) to adjust the stop second hand (1), a
short push for minute steps, a longer push for continuous adjustment.
Following correct adjustment of all hands, press the crown back into
position A and lock the crown with the security cover (9) to avoid
unintentional adjustment of the hand position.

Declaration of conformity
Uhrenfabrik Junghans GmbH & Co. KG hereby declares that this wrist-
watch conforms to the fundamental requirements and other relevant
specications of Directive 1999/5/EC.
A corresponding declaration of conformity can be requested at info@
junghans.de.
5. Operational readiness J622
To maintain your solar wristwatch in an operational condition you
should keep it in as bright a place as possible. Please note that the
solar dial should not be covered by clothing for long periods as this can
reduce the operational capability of your watch. If the energy store is
discharged, hold your watch in bright light to recharge it rapidly. The
charging time of your solar wristwatch is dependent on the intensity
of the light source and the design of the solar dial. The guideline values
stated in the tables (page 32 + page 37) serve as an aid here.
Important:
Do not hold your wristwatch too close to heat-generating light
sources! Do not leave your watch in direct sunlight for long periods!
Temperatures above 50° C may result in damage to the watch!
