TOLERANCES

Mechanical movements
The precision of a mechanical movement varies de-
pending on the wearer’s habits. The majority of
LONGINES watches have a precision of between -15
and +15 seconds per day.

Quartz movements
The ambient temperature affects the precision of a quartz
movement, which will be between -0.3 and +0.5 sec-
onds per day.

liant style.

include minute imperfections which are hardly visible un-
der tenfold magnification.
The colour: the colour of the diamonds used by Longines
is Top Wesselton.
The weight: the weight of a diamond is measured in
carats, one carat being equal to one fifth of a gram.

WATER-RESISTANCE / CROWN AND SCREW-IN PUSH-PIECES

Precautions regarding water-resistance
If your watch is water-resistant it is essential that the seals
be checked each year before the bathing season be-
cause, 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
ቢ
Certain Longines models have a screw-in crown which
has to be unscrewed before each adjustment by turn-
ing it anti-clockwise (fig. ቢ).
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. ባ).

THE SAME APPLIES FOR THE SCREW-IN PUSH-PIECES
ባ

IMPORTANT! You should always push 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.

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 en-
ables 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 time-
piece 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 hours, min- L614, L699
