AUTOMATIC FUNCTIONS OF YOUR WATCH
Synchronization accurate to the second
During the night, your watch’s receiver is switched on at 2:00, 3:00, and
if required at 4:00, 5:00, and 6:00 a.m. and the internal time memory is
synchronized by radio signal accurately to the second. At these switch-
on times the radio tower symbol flashes. If all automatic attempts to
receive the radio signal fail to produce exact synchronization, the
number in the reception indicator moves up by one. Days in which there
is no reception are added together. On such days, your watch still
operates very accurately on the quartz time base due to the internal
time memory. The next time that a successful reception makes
synchronization possible, the reception indicator is reset to zero.
Changeover from summer time to winter time and vice versa
If reception conditions are good, your watch changes from standard
time to daylight savings time, or vice versa at 2 a.m. or 3 a.m. If the
interface prevents reception, the changeover may be delayed until later
in the morning.
Battery change indicator
If the second display or date display flashes, this indicates that the
battery voltage has dropped below 2.4 V. All watch functions still
operate normally; however, the battery should be changed within the
next few weeks.
