54 International guarantee / Recommendations
RECOMMENDATIONS
Like any micromechanical precision instrument, your
LONGINES watch should be checked at least every two
years.
If you have a self-winding watch, it has a power-reserve
of around two days. If necessary it can be wound manually.
If you have a quartz watch the electrical power is supplied by a battery. After 12 to 18 months of use (with the
exception of watches with lithium batteries) the voltage
in the battery may drop suddenly and cause your watch
to stop. Som
e models have a battery end-of-life func-
ti
on. The seconds hand will start to jump every 4 seconds. If this happens we recommend that you replace
the battery immediately, because once the battery
runs down totally it may damage your watch.
Collection and treatment of end of life quartz watches*
This symbol indicates that this product
should not be disposed with household
waste. It has to be returned to a local authorized collection system. By following this
procedure you
will contribute to the protection of the environment and human health. The recycling
of the materials will help to conserve natural resources.
*valid in the EU member states and in any countries with corresponding legislation.
Replacing the battery
We recommend that you contact an approved
LONGINES service centre or authorised LONGINES retailer, as they are equipped with the tools and apparatus required to carry out the work and the necessary
checks in a profession
al manner. A worn-out battery
sho
uld be replaced immediately in order to reduce the
risk of leakage and consequent damage to the movement.

Recommandations
55International guarantee / Special recommendations
SPECIAL RECOMMENDATIONS
What can I do to ensure that my LONGINES watch
functions perfectly for many years?
Magnetic fields: avoid putting your watch on a loud-
speaker or on a refrigerator because these machines create magnetic fields that may damage it.
Salt-water: always rinse your watch in fresh water after
swimming in the sea.
Shocks: avoid subjecting your watch to any shocks, including sudden changes in temperature.
Screw-in crown: always make sure you have screwed the
crown in ful
ly to avoid any humidity getting into the
mechanism.
Push-in crown: always push the crown back into the neu-
tral position to avoid any humidity getting into the
mechanism.
Cleaning: use a tooth-brush and soapy water to clean
metal bracelets and water-resistant cases and a soft cloth
to dry off afterwards.
Chemical products: avoid all direct contact with solvents,
detergents, perfume, cosmetics, etc. which may damage the bracelet or strap, the case or t
he seals.
T
emperatures: avoid exposing your watch to extreme tem-
peratures (over 60°C or 140°F and under 0°C or 32°F)
and to sudden fluctuations in temperature.
Water-resistance: we cannot guarantee that your watch
will be permanently water-resistant. The seal may be affected by wear or by an accidental shock to the crown.
As recommended in our service instructions, you
should have the water-resistant seals of your watch tested once a year by an approved LONGINES agen
t.
Chronograph push-pieces: do not adjust the push-pieces
unde
r water as this may allow humidity to get into the
mechanism.
Occasional winding: if your watch has not been worn for
44 hours or more, wind it manually with the crown in position 1.
How often should my watch be serviced?
Like any other precision instrument a watch should be
serviced regularly to ensure that it runs perfectly. We cannot say how often you should have your watch serviced
as this depends on the model, t
he climate where you
l
ive and how you look after the watch yourself. As a rule,
a watch should be serviced every 4 or 5 years, depending
on the conditions in which it is worn.
Where should I go to get my watch serviced or for a
new battery?
We recommend that you go to an approved LONGINES
agent or retailer. They are the only people who have the
necessary tools and apparatus to work on your watch
and to carry out the necessary checks to a professional level. Moreover, only specialists ca
n guarantee that their
work
meets the stringent quality standards set by
LONGINES.

CERTIFICATE OF AUTHENTICITY
Longines bows to the paragon of beauty: the diamond
This certificate of authenticity guarantees the quality of
each precious stone selected by Longines’ specialists.
The cut: Longines diamonds are cut in the traditional brilliant style.
The purity: the degree of purity of a Longines diamond
is VVS (very very small inclusions). This means that it may
include minute imperfections which are hardly visible under tenfold magnification.
The c
olour: the colour of the diamonds used by Longines
is Top Wesse
lton.
The weight: the weight of a diamond is measured in
carats, one carat being equal to one fifth of a gram.
Anglais ME Longines 7.4.2010 11:42 Page 60
Page 13
Precautions regarding water-resistance
If your watch is water-resistant it is essential that the seals
be checked each year before the bathing season because, without your realising it, they might have been
damaged as the result of a shock.
If the case has to be opened for any reason the seals
for the glass and the case-back as well as the crown
(and/or push-pieces) must be checked and, if necessary,
replaced.
Screw-in crown and push-pieces
Certain Longines models have a screw-in crown which
has to be unscrewed before each adjustment by turning it anti-clockwise (fig.햲).
After use, return the crown to position 2, then push in
and screw in firmly in position 1 to ensure that the seal
with the case is water-resistant (fig. 햳).
THE SAME APPLIES FOR THE SCREW-IN PUSH-PIECES
IMPORTANT! You should alwayspush the crown (and/or
the push-pieces) right in and screw in firmly to ensure
a water-resistant seal with the case.The crown (and/or
push-pieces) should never be adjusted if the watch is
in a humid atmosphere.

Power-reserve indicator
Certain watches have a power-reserve indicator (calibres
L602, L693, L697).
If the watch is worn rarely or not at all, the hand will gradually shift anti-clockwise. When it indicates that the
power-reserve is below 1/4, the watch should either be
wound
or worn to avoid it stopping.
When the watch is wound the power-reserve indicator
will shift clockwise.

L614, L699 – THE LINDBERGH HOUR ANGLE WATCH
The original Lindbergh Hour Angle Watch was designed
by Charles Lindbergh as a navigational aid for pilots. Used
with a sextant and a nautical almanac, this watch enables the wearer to quickly determine the hour angle from
Greenwich, in other words his or her longitude.
Thanks to its ingenious combination of dials, this timepiece differs from an ordinary watch in three ways:
A The indications on the dial are designed in such a way
that they show simultaneously the time (in h
ours, min-
ute
s and seconds) and the hour angle (in degrees and
minutes of arc).
B The rotating central dial shows the seconds and it can
be turned using the crown in order to synchronise the
watch with a time signal.
C The bezel can be rotated to correct the equation of
time (which varies from one day to the next).
3-position crown
Winding
(crown pushed right in)
The natural movements of your wrist will automatically
wind your Longines watch, which has a power-reserve
of 42 hours.
It is only necessary to wind the watch man-
u
a
lly if it has not been worn for several days.
Adjusting the time and stop seconds
Pull the crown right out to position 3. The seconds hand
will now stop. Adjust the time by turning the crown in
either direction. Synchronise the watch with a time signal (telephone, radio, TV) and then push the crown back
in to position 1.
Synchronising the watch with a time signal
In the intermediate position 2, the crown can be used
to turn the central dial (in either direction). Pull the crown
out
to the intermediate position 2 and turn the central
dial so that the seconds hand points to the “60/15” position on the last pip of the time signal. Push the crown
back in to position 1.
Push-piece D at 4 o’clock
This is for opening the case back, thus revealing the
movement through a protective sapphire glass.
The space/time dial and how it works
The design of the whole of The Lindbergh Hour Angle
Watch takes into account the fact that the Earth revolves
thr
ough 360° in 24 hours, through 180° in 12 hours,
through 15° in 1 hour and through 15’ of arc in 1 minute.

Anglais ME Longines 7.4.2010 11:44 Page 77
Page 30
78 Self-winding watches
L614, L699 – THE LINDBERGH HOUR ANGLE WATCH
Consequently:
The hour hand indicates 15° per hour. One complete cir-
cle of the dial (12 hours) is equivalent to 180°.
The minute hand indicates 1° per 4’, in other words 15°
per hour. Each of the 15° is subdivided into four sectors
of 15’ of arc. All these indications are engraved on the
rotating bezel.
One complete circle of the centre seconds is equivalent
to 15’ of arc. The rotating central dial is divided into 60’’
and 15’ of arc.
How to use your Lindbergh Hour Angle Watch
Having synchronised your watch with a time signal. As
an example when you check it your watch shows
4 hours, 37 minutes and 12 seconds. The equation of
time for the day in question is minus 4 minutes and
50 seconds.
Therefore move the marker situated at “15” on the bezel
4 graduations to the left. These graduations represent
the minutes engraved around the case.
Your data are as follows:
Seconds hand (centre dial) 3’
Minute hand (bezel) 10° 15’
Hour hand (main dial) 6
0°
As you have only turned the bezel by 4 minutes, you still have to take into account the
50 seconds (the equation of time being
4 minutes and 50 seconds for the day in
question).
On the central dial, the 50 is opposite 12½ . /. 12½’

(your longitude) 70° 5½’

83Chronographs – General information
CHRONOGRAPHS – GENERAL INFORMATION
The chronograph
The chronograph is an instrument for measuring short
periods of time. It is used mainly in sport but also in aviation or for scientific experiments, for example.
Column Wheel
The column-wheel movement is reputed for the feeling
of crisp efficiency its handling provides. In particular, the
instant responsiveness of its pushpieces adds to the
pleasure of using the chronograph.
Split-seconds function
In a chronograph with a split-seconds function, a second hand is superimposed over the trotteuse. When intermediate times are read off, only the split-seconds hand
stops. When the push-piece is pressed again, it catches up with the trotteuse.
Tachometric scale
The tachometric scale is a series of graduations on the
dial or the bezel of the chronograph that enable the user
to determine mean speeds on the basis of an observation
time of less than 60 seconds.
Measure the time needed to cover 1 kilometre (or 1 mile).
The position of the seconds hand when it stops indicates
the mean speed. If it takes 30 seconds to cover 1 km
(or 1 mile), the scale will indicate a mean speed of
120 kph (or 120 mph).
IMPORTANT! The time should not be adjusted while the
chronograph function is being used.
