The «1000 Hours Control» seal or marking, affixed or
engraved on the back of your watch, certifies that it has
undergone this observation programme in our laboratories
and has successfully passed all tests. The latter include rate
regularity checks, reactions to changes in temperature and
barometric pressure, resistance to shocks and magnetic fields,
as well as water-resistance tests. Your watch is therefore
capable of withstanding the trials of everyday life when you
wear it on your wrist.
The criteria of the “1000 Hours Control” programme go far
beyond the official timekeeping test standards, which concern
only part of the movement. Jaeger-LeCoultre tests both the
movement and the fully cased-up watch.
Compression keys
Equipping the crowns of the Master Compressor line models,
the patented compression key system can apply strong com-
pression to one of the 4 crown seals, thereby ensuring impec-
cable long-term water resistance.
The “open” or “closed” position of the compression key is
indicated by the arrow symbols (viewed from the dial side) :
- The compression key is in the compressed seal position
(“closed”) if the indication is a white arrow; the keys must
be closed when you wear your watch and when you are
taking part in sports. You must not make any adjustments
or set the time in this position, since this might damage the
gaskets.
- The compression key is in the non-compressed seal posi-
tion (“open”) if the indication is represented by two red
arrows; in this configuration, you may proceed to start the
watch and adjust the functions according to the indications
below.
The transition from the “closed” to the “open” position, or
vice-versa, is performed by turning the key using the wing-
nuts in the direction indicated by the arrow(s).
Note
The water-resistance function of the compression key is sepa-
rate from the operation of the crown itself. Even in closed
position, the key does not lock the crown. It is thus in practice
possible to handle the crown when the key is in the com-
pressed seal position. However, as mentioned earlier, it is
extremely inadvisable to make adjustments in this position,
since this might damage the seals. We recommend that you
first turn the compression key to the “open” position before
performing any adjustments on your watch.
Adjusting the bracelet
You can adjust your steel bracelet yourself. However, if you
have a gold model, we advise you to entrust it to the nearest
approved Jaeger-LeCoultre retailer, or to contact one of our
official Service Centres listed at the end of the guarantee
booklet.
Adjusting the steel bracelet
Place the watch on your wrist. You can thus see how many
links need to be added or removed.
Remove your watch by simultaneously pressing the pushpieces
on either side of the clasp.
Hold the bracelet near the clasp. Using the adjustment tool,
press the end of the bar (fig. 1) and lift up the link (fig. 2).
Avoid the 2 links on either side of the clasp.
Proceed in the same way for the following link (fig. 3) if you
want to remove a single row of links (or the 2
nd
, 3
rd
, etc. if you
want to remove 2, 3... rows of links).
Take out the two bars (fig. 4).
Remove the row(s) of links (fig. 5).
Place the 2 ends of the bracelet back together and insert a
bar (fig. 6).
Tip over the link, press on the end of the bar pivot and push
your link down until it clicks (fig. 7).
