Introduction
Your new TAG Heuer 2000 Aquagraph has been designed and developed to
satisfy the criteria of quality and security required by professional divers.
During a dive, the watch is more than a necessary accessory – it is vital. Your
TAG Heuer 2000 Aquagraph has been designed to be a constant reference
and the last reliable indicator when all other instruments have stopped.
Your TAG Heuer 2000 Aquagraph has two unique, distinctive features:
–its Calibre 60 self-winding movement which displays the chronograph min-
utes and push-buttons that remain operational down to 500 m
–its totally secure unidirectional turning bezel
In addition, your TAG Heuer 2000 Aquagraph has all the technical charac-
teristics of an authentic professional divers’ timepiece:
–water-resistance to 500 m, tested on each timepiece;
–automatic helium escapement valve;
–screw-in crown with security indicator;
–scratch-resistant sapphire crystal;
–secure clasp with diver’s extension for the models fitted with a steel bracelet;
–luminous pointers.

Like every high quality watch, your TAG Heuer requires attentive care.
Compliance with a few basic recommendations will help to maintain its
reliability and ensure that the watch is effectively protected against wear
and tear.
Rinsing. Please rinse your chronograph regularly in fresh, soapy water,
especially after every use in salt water.
Condensation. On exposure to sudden temperature changes, condensation
may form under your chronograph crystal. This mist does not under any
circumstances imply that your timepiece has ceased to be water-resistant.
It will disappear of its own accord and does not affect the proper working of
your watch. If the condensation persists, please consult your TAG Heuer
watchmaker.
Sealing gaskets. With the passage of time, the sealing gaskets of your
chronograph may deteriorate. We advise you to have the water-resistance of
your watch checked once a year by your TAG Heuer watchmaker. If necessary,
he will replace the sealing gaskets.
Bracelets. To prevent accidental opening, our steel bracelets are fitted with
a double safety clasp.

Your TAG Heuer 2000 Aquagraph is fitted with a self-winding mechanical
movement, the Calibre 60. This choice guarantees the proper operation of
your timepiece in every situation. Even if a drop of water were to penetrate
inside the case, the Calibre 60 would continue to function because it is
mechanical.
One particularly important and unique feature of the TAG Heuer Calibre 60 is
the central position of the chronograph minutes hand on the dial instead of in
a counter as on a traditional chronograph. This permits clear and immediate
reading of this information which is essential to measure the duration of the
decompression stages.

self-winding chronograph movement
The unidirectional turning bezel of your
TAG Heuer 2000 Aquagraph, fitted with
precision stop pawls, enables you to
measure your diving time precisely. The
catches on of the rotating bezel make it
easy to operate, even when wearing thick
diving gloves.
For still greater security, the TAG Heuer
2000 Aquagraph is fitted with a unique
system which keeps the bezel locked at all
times. Pressure must be exerted on the
base of the bezel to make it rotate (fig. 1).
When this pressure ceases, the bezel will
automatically lock in its current position.
The bezel cannot therefore turn accidentally.
When you start your dive, set the zero
marker on the bezel against the minutes
hand (fig. 2).

At every moment, the position of the
minutes hand on the bezel will indicate
the number of minutes which have elapsed
since the start of the dive (fig. 3).

Your TAG Heuer 2000 Aquagraph is fitted
with a screw-in crown with safety gaskets
which guarantee its water-resistance to a
depth of 500 m.

Pos. 3: crown released and pulled out to
position 3: the hour and minutes
can be set on the main dial and
24h indicator. The 24h indicator
shows whether the time displayed
on the main dial is AM or PM.

For example, if the hours and minutes
hands on the main dial read 10.10, the
24h indicator shows whether the time is
10.10 AM (fig. 5) or 22.10 (i.e. 10.10 PM)
(fig. 6).
The time shown on the 24h indicator is
adjusted as a function of the hour and
minute hands on the main dial.
Important: the crown must be screwed
back in correctly to guarantee water-
resistance of the timepiece. If a coloured
ring can be seen on the crown, this indicates
that the latter has not been screwed in
correctly.

The chronometer functions are actuated by pressing the push-pieces. These
remain operational down to a depth of 500 m.
The unique feature of the TAG Heuer Calibre 60 is to permit clear and imme-
diate reading of the chronograph minutes; this information is vital to measure
the duration of the decompression stages.
Warning: before each timing operation, reset the hands to zero. If neces-
sary, use push-piece B to effect a zero reset.

1. Start: push-piece A (START)
2. End: push-piece A (STOP)

2. Additional timing:
This function enables several consecutive times to be measured by totalizing
to obtain the aggregate total time.
1. Start time 1: push-piece A (START)
2. End time 1: push-piece A (STOP)
>Read time 1
3. Start time 2: push-piece A (START)
4. End time 2: push-piece A (STOP)
>Read time 1 + time 2

Automatic helium escapement valve
The automatic helium escapement valve
(fig. 7) meets the needs of hyperbaric
divers who spend several days in diving
caissons and breathe a gas mixture which
is highly enriched with helium.
Helium is a very light and volatile gas,
which may infiltrate the chronograph on
exposure to substantial pressure in the
caisson. When the diver rises to the surface,
all the gases expand as the pressure falls.
The helium trapped in the chronograph is
unable to escape as quickly as it entered.
Overpressure builds up inside the case and
the valve will automatically be actuated to
allow the helium to escape, thus preventing
damage to the chronograph.

You have (fig. 8):
–2case attachments
–2bars
–1bracelet with diver’s extension
–1tool
Take the case attachment, place it on the
bracelet section (1st link), pass the bar
through the case attachment and the first
link. Grasp the watch and turn it over; the
watch glass must now face downwards.
With the watch in this position, compress
one pin of the bar by means of the tool
and tilt the case attachment so that the
compressed pin rests in the space
between the horns.
Proceed in the same way with the second
pin; then press the case attachment so that
the bar pins notch into the holes provided
for them.
