This means that it may include minute imperfections which are hardly visible un- der tenfold magnification. The colour: the colour of the diamonds used by Longines is Top Wesselton.

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. Water-resistance / Crown and screw-in push-pieces 61
