Precautions concerning waterresistance
A watch’s water-resistance can be affected by changes caused by the gaskets
drying out, or an accidental shock to the crown. To help maintain your watch’s
water-resistance, we recommend rinsing it in soft water after any contact with
sea water and having its water-resistance checked once a year by an approved
LONGINES Service Centre. In no circumstances should you open your watch
yourself.
IMPORTANT! Never activate the time-setting crown and/or push-pieces when the
watch is underwater, and ensure that the crown and push-pieces are pushed in
or screwed down before any immersion in water.

CHRONOGRAPH L687 5
Avoid setting the time while the chronograph function is in use
Setting the time and stop seconds
Pull the crown out to position 3 when the small seconds hand (situated at 9
o’clock) is at 60. Turn the crown either way to the desired time display. As
soon as the time is synchronised, push the crown back into position 1.
Please refer to the 24H indicator to adjust to the desired time, in terms of
a.m. or p.m.
Avoid any date, month and day correction, or use of the corrector 4, between
19:00 and 06:00; this could damage the mechanism.
Quick date and month correction
Pull the crown out to position 2, and then turn it backward to the desired
date and month display. During this operation, your watch will continue to
run; no time adjustment will be required. The date needs to be corrected after
every month shorter than 31 days. Push the crown back into position 1. The
date will change when the hour hand passes midnight.
Moon phase correction
Pull the crown out to position 2, and turn it forward until the full moon
appears in the centre of the moon phase window. Find out the date of the last
full moon, and turn the crown forward through as many revolutions as the
number of days elapsed since the last full moon, then push the crown back into
position 1.
Day correction
Press the corrector 4 situated at 10 o’clock to correct the day using the
corrector tool.
Before each timing operation, the chronograph hands must be at their start
point.
Standard Start Stop Reset function
Used for timing a single event: · Press push-piece 2: the chronograph will
start. · Press push-piece 2: the chronograph will stop. · Press push-piece 3
to reset.
Rally Add function (partial times)
Used for measuring successive events, but not the intervals between them. Each
result is automatically added to the preceding one. To time the various stages
of a car rally, for example, follow the procedure below: · At the start of the
first stage, press push-piece 2:
the chronograph will start. · At the end of the first stage, press push-piece
2
again: the chronograph will stop. · Repeat for each stage of the rally. · At
the end of the final stage the chronograph will
show the total time of the rally, in other words, the accumulated time for all
the stages. · Press push-piece 3 to reset.
