WATER-RESISTANCE / SCREW-IN CROWN AND PUSH-PIECES
57
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 neces-
sary, 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.
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).
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.
