been defined from +1 to +12 hours moving
eastward and 12 others from 0 to -11 hours
moving westward.
Jaeger-LeCoultre has personalised each of
these time zones with the name of a city that
is displayed in the window situated at 6 o'clock
on the dial of your watch.
In order not to compromise overall legibility, the
city disc does not display those regions where
the time differs by a fraction of an hour, (e.g.
India, Iran, Nepal).
The minute hands of the two time zones
on the Master Control Geographic advance
simultaneously.
Pre-setting: synchronising local reference time
and the time of the 2
nd
time zone
The mechanism of the 2
nd
time zone requires
pre-setting, which consists of synchronising the
time in the 2
nd
time zone with the local place
and time. This operation is designed to inform
the mechanism of the reference time and place
(i.e. local time and place).
This step needs to be carried out only once, as
long as the reference zone remains unchanged.
