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 suddenlyand cause your watch
to stop. Som

ti
e models have a battery end-of-life func-
onds. If this happens we recommend that you replace
the battery immediately, because once the battery
runs down totally it may damage your watch.

SPECIAL RECOMMENDATIONS
Recommandations
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 thesemachines 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
mechanism.
Push-in crown: always push the crown back intothe neutral position to avoid any humidity getting into the
mechanism.
Cleaning: use a tooth-brush and soapy water to clean
metal braceletsand water-resistant casesanda softcloth
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
emperatures: avoid exposing your watchto extremetem-
T
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

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 regularlytoensure that it runsperfectly. We cannot say how often you should have your watch serviced
as this depends on the model, t
l
ive and how you look after the watch yourself.As a rule,
a watchshouldbeserviced every 4 or 5 years,depending
on the conditions in which it is worn.

WATER-RESISTANCE / CROWN AND SCREW-IN PUSH-PIECES
Precautions regarding water-resistance
If your watch is water-resistant it is essential thattheseals
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
햲
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
햳
IMPORTANT! Youshould alwayspush the crown (and/or
the push-pieces) right in and screw in firmly to ensure
a water-resistantsealwiththecase. The crown(and/or
push-pieces) should never be adjusted if the watch is
in a humid atmosphere.

Power-reserve indicator
Certain watches havea power-reserve indicator (calibres
L602, L693, L697).
If the watch is worn rarelyor 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.

The original LindberghHour Angle Watchwas designed
by CharlesLindbergh as a navigationalaid 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 aredesigned in such a way
that they show simultaneously the time (in h
s and seconds) and the hour angle (in degrees and
ute
minutes of arc).
B The rotating central dial showstheseconds 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).

The space/time dial and how it works
The design of the whole of The Lindbergh Hour Angle
Watch takes into accountthefactthattheEarth revolves
ough 360° in 24 hours, through 180° in 12 hours,
thr
through 15° in 1 hour and through15’ of arc in 1 minute.
77Self-winding watches
Page 30
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
As you have only turnedthebezel 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’

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.
IMPORTANT!The time should not be adjusted while the
chronograph function is being used.
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.
Tac hometric 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 speedsonthebasis 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).
