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 passed all the tests, relating to rate regularity,
temperature and atmospheric pressure, resistance to impacts
and magnetic fields, as well as water-resistance. Your watch
is therefore capable of withstanding the trials awaiting it in
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 not only
the movement before casing it within the watch, but also the
watch as a whole.
Compression keys
Equipping the crowns of the Master Compressor line models,
the patented compression key system can apply strong
compression to one of the 4 crown seals, thereby ensuring
impeccable 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
position (“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
separate 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
compressed 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).
