2. Readiness for use
So that your watch is always ready for use, you should make sure that it does
not run low on power. The watch regularly checks to see if it has sufficient
battery power. If it no longer has enough (e.g. the battery has run out or
ambient temperature is too low, which impairs battery performance), the
second hand stops at the 12 o’clock position. A battery symbol and the cur-
rent second also appear on the LCD display. If the battery does not recover
(e.g. through an increase in the ambient temperature), you should take the
watch as soon as possible to your authorised specialist to have the battery
changed, or send it to have this done to the Junghans Service Centre.
Battery type: CR 1632
Typical life: Approx. 2 years
Please ensure that the battery is disposed of properly in accordance with
statutory regulations.
3. Automatic time synchronisation
Daily, fully automatic time synchronisation takes place overnight. While the
signal is being received the second hand temporarily stops in the 9 o’clock
position. During this time, the LCD display is turned off (nothing is shown).
After the time has successfully been automatically synchronised, the original
mode is again shown in the display. The date is always advanced automati-
cally by the time signal. This process also takes the 29th of February into
account in leap years.
If all of the attempts at picking up a signal lead to no clear synchronisation,
the reception indicator goes up by 1 (see also the description of ‘Reception
indicator’ mode in section 5.5). Any further days without synchronisation are
added to this. During any such days without synchronisation, your watch
For the USA’s WWVB time signal transmitter the following specific featu-
re applies:
After a successful transmitter call or battery change (restart), your
Junghans multi-frequency radio-controlled watch always reads in Pacific
Standard Time.
Due to the non-uniform changeover from summer to winter time and the
differing time zones in the individual US states, you are given the oppor-
tunity to adjust winter time, summer time and time zone settings (see 5.7)
manually.
If, due to where you are, the time zone or summer / winter time that you
have set differs from PST, it is nevertheless retained during any subse-
quent transmitter call or automatic synchronisation.
