ENGLISH Junghans. Live your style.

Congratulations on becoming the owner of an original Junghans!

Junghans watches are and always have been something special.

They have made watchmaking and design history. And we are

still doing so today. For the story of success that began in 1861 in

Schramberg in the Black Forest continues with each new model.

Present in every watch are the elements that make Junghans

special: style, passion, innovative spirit and precision right down

to the tiniest detail. Put another way: when traditional crafts-

manship, leading edge watch technology and classy design come

together, then it is a genuine Junghans. A watch for all those

who live their own style – and on that we can not do other than

congratulate you!

Operating instructions Calibre J830

Important note:

Do not make any changes to the date between 08:00 p.m. and

02:00a.m., as the date is automatically advanced by the movement

during this period and you could damage the date advance mechanism.

Your watch features two screwed crowns. These crowns must be

released before they can be operated.

Winding up the watch

The automatic movement can also be wound by hand using the crown

(5) exhibiting the Junghans star. Unscrew the crown by turning to the

left. A minimum of 2 to 3 rotations of the crown is required in order

to actuate the movement. The watch is fully wound after approx.

45rotations of the crown. Maximum accuracy and maximum power

reserve are guaranteed when the watch is fully wound (even if the

watch is put down). Then press the crown into Position A again and

screw-in. Once set, the watch should be worn on the wrist to ensure

that it remains operational at all times via automatic winding (through

motion of the rotor).

Adjusting the time

Release the crown (5) and pull it into position C. This will stop the

watch. Setting of the watch to the precise second can be achieved by

stopping the movement as the second hand passes over the ‘60’ mark.

The minute hand can now be positioned precisely to the respective

minute marker in order to set the desired time. Press the crown into

Position A again and tighten.

Setting the date

Release the crown (5) and pull it into Position B. Set the date by turning

the crown to the right. Then press the crown into Position A again

and tighten. It should be noted that resetting the date is not advised

between 8pm and 2am as the date is switched automatically by the

movement during this period, whereby the switching mechanism

could otherwise sustain damage. If the month has less than 31 days,

set the date manually to the 1st day of the next month.

Setting the 2nd time zone

Release the crown (3) exhibiting the snowflake symbol and pull it into

Position B. Turning the crown to the right will adjust the time forwards,

or alternatively backwards by turning to the left. Press the crown into

Position A again and tighten.

General information

External inuences can aect the watch’s waterproof qualities, which

may let in moisture. We therefore recommend that you have your

watch regularly inspected by your Junghans specialist. Other servicing

tasks or wrist strap repairs should also be done by your Junghans

specialist. Your watch is tted with a quality wrist strap that has

undergone multiple inspections in our factory. If, however, you decide

to change the strap, please t a new one of the same quality, preferably

an original Junghans wrist strap. Watch and wrist strap can be cleaned

with a dry or slightly moistened cloth.

NB: Do not use chemical cleaners (e.g. benzine or paint thinners). These

may harm the surface.

The water resistance as prescribed by DIN is a design engineering

characteristic which is susceptible to external inuences such as shock,

uctuations in temperature, UV light and direct contact with cosmetics

and cleaning products (greases and acids). The “3–30 BAR” condition is

thus only applicable for brand new watches. We recommend having the

watch inspected at regular intervals.
