FUNCTION
The GMT (Greenwich Mean Time) system, also known as universal time and
adopted throughout the world, divides the terrestrial globe into 24 one-hour
sections (time zones), each equivalent to 15° of longitude. The Greenwich
meridian was taken as the fundamental reference meridian for the localisation
of time zones by the international conferences held in Rome in 1883 and in
Washington in 1884. Starting from meridian zero (or Greenwich meridian), 24
time zones have been defined, from 0 to +12 towards the east, and from 0 to
-12 towards the west. The zero meridian has a very important function for
sailors: the time at Greenwich is the reference for the calculations which
enable the longitude at sea to be determined, and thus the establishment of
the ship’s exact position. The GMT function of the Panerai Luminor 1950 10
Days GMT enables the local time and the time in another country (home time)
to be read at the same time.

ETTING THE SECOND TIME ZONE
1. Raise the lever of the device protecting the winding crown
(A)
and pull out
the winding crown
(B)
to the first click
(position 1)
.
2. Set the required time. The hour hand
(C)
will move at intervals of one hour
and will indicate the local time, that is, the time in the place where it is located
at that moment.
3. At this point, the hand of the second time zone
(E)
will indicate the home
time, that is, the time in the country of departure. This hand moves at the same
rate as the local time hour hand
(C)
, making a complete revolution in 12 hours.
At the 9 o’clock position, on the small seconds dial, a further hand
(F)
displays
the GMT time divided into 24 hours, to avoid possible confusion between
morning and afternoon.
3. Set the correct time. Use the hand
(F)
to check that the time is correctly
set to before midday or after it. If, for example, it is 3 o’clock in the afternoon,
check that the hand
(F)
is in the left part of the small seconds dial.
4. Return the winding crown
(B)
to the initial position
(0)
and close the lever
of the device protecting the winding crown
(A)
.

HE SECONDS RESET DEVICE
The small continuous seconds dial
(G)
is located at 9 o’clock. When the
winding crown
(B)
is unscrewed and pulled out to the second click
(position 2)
the small seconds hand is immediately moved to zero. The seconds reset device
provides an extremely precise way of synchronising the watch with the time
source being used as a reference.
Note: At the moment that the seconds reset device comes into operation the
seconds hand is zeroed and the balance is stopped. If the crown should
inadvertently be pulled out to
position 2
for a long time, the precise setting of
the time must be carried out again.

ETTING THE DATE
The Luminor 1950 10 Days GMT watch has a gradual date change mechanism,
a process which takes about 3 hours to complete: from 10 p.m. to 1.00 a.m.,
with a margin of ± 30 minutes. This particular method of changing the date is
inspired by the mechanical tradition of Swiss watchmaking, and it allows the
date to be changed in both directions, moving it either forwards or backwards.
To set the date indicated, proceed as follows:
1. Raise the lever of the device protecting the winding crown
(A)
and pull out
the winding crown
(B)
to the first click
(position 1)
. Turn it clockwise or anti-
clockwise until the correct date appears in the date window located at 3 o’clock.
If the date changes when the hour hand
(C)
goes past 12, 12 corresponds to
midnight, otherwise it corresponds to midday.
