Replacing The Battery; Battery Type - Longines L441 Mode D'emploi

Important notes
a) It is possible to combine the various Chrono functions
(SIMPLE, ADD & SPLIT) in the same timing operation.
b) Unless the chronograph is stopped (STOP pressed), the
chronograph hands will not stop running. Continuous
running of the chronograph will greatly reduce the autonomy
of the movement.
Battery end-of-life mode (EOL)
When the battery is fitted, its voltage is measured by the micro-
controller. If the voltage is below the EOL level, the chronograph
functions are suspended, and the movement small seconds
is stopped.
If the battery voltage decreases and the risk of function loss
arises, EOL mode is activated. EOL mode is activated if the
battery voltage is below the EOL level for more than one hour.
If the battery voltage climbs above the EOL level for more than
15 minutes, EOL mode is deactivated. This scenario may occur
in particular if the watch has been temporarily exposed to low
temperatures.
In this mode:
• The small seconds hand moves jerkily. The hand moves
4 steps quickly, and then remains immobile for 4 seconds.
• The chronograph can no longer be activated (
approximately one hour after EOL mode has been activated.
• If the chronograph was active at this time, it will continue to
run, though there could be step loss.
Quartz movements
The ambient temperature influences the precision of a quartz
movement, which can vary from – 0.3 to + 0.5 seconds per day.
If your watch is quartz, the electrical energy is supplied by
a battery. After 12 to 18 months' use (with the exception of
watches equipped with lithium batteries), the battery voltage
may fall abruptly and cause a watch stoppage. Certain models
Longines_MDE-L441.indb 33
are equipped with a battery end-of-life indicator (EOL). On these,
the seconds hand will jump every 4 seconds. In this case, it is
recommended to have the battery replaced immediately, since
once drained, it could cause internal damage to your watch.
