INTRODUCTION
With its know-how and long tradition
of inventiveness, the Jaeger-LeCoultre
Manufacture has shown exceptional
creativity since 1833, resulting in a level
of technical expertise that has led to
the design of some of the most sig-
nificant complications of the early 21st
century.
With an exceptional mastery of watch-
making, Jaeger-LeCoultre seeks to con-
stantly push the limits of the imagination
with each new creation, thus blending
aesthetic appearance, technical perfor-
mance, and unique functions.
With the Master Hybris Mechanica
Calibre 184 model, the Grande Maison
of the Vallée de Joux has once again
produced an exceptional creation that
combines elegance, the best of watch-
making tradition, and the very latest in
innovation.
With an overall thickness of only 14.08
mm, the watch is a prime example of in-
novative design, drawing on 12 dierent

32
patents. The entire process of develop-
ing this new model has been guided by
the twin bywords of ingenuity and per-
formance.
The Master Hybris Mechanica Calibre
184 features the signature Jaeger-
LeCoultre 5th generation Gyrotourbillon,
a Perpetual Calendar, and a new Minute
Repeater with a Westminster chime.
ACCURACY AND
PRECAUTIONS
FOR USE
MANUALLY WOUND
MECHANICAL MODELS
The accuracy of watch models with
mechanical movements is determined
by the balance wheel. This oscillates at
a rate of 28,800 vibrations per hour.
Despite all the care that the master
watchmakers of the Jaeger-LeCoultre
Manufacture have lavished on building
and assembling your watch, its accuracy

ENGLISH
33
is subject to the influence of gravity,
magnetic fields, accidental impacts,
and the ageing of the oils. The accuracy
of a watch is measured by its regularity
of rate in various positions.
Your individual activities could be the
cause of slight irregularities in the work-
ing of your timepiece. If you observe a
discrepancy in the way your watch runs,
we advise you to entrust it to an au-
thorised Jaeger-LeCoultre retailer who
will make the necessary adjustments.
Watches with mechanical movements
must not be used for sports involving
significant risk of impact or abrupt ac-
tions, such as golf or tennis.
WATER RESISTANCE
Your Jaeger-LeCoultre watch is water-
resistant to 5 bar. Its water resistance
can be identified by the symbol
and/or the engraving: “5 bar” on the
case-back. This means that your model
has been tested at an overpressure of

34
5 bar, corresponding to an immersion
pressure of 50 metres (1 bar = ±10 me-
tres).
In accordance with the ISO 22810/
NIHS 92-20 standard, in order to guar-
antee the durability of the watch’s
characteristics over time, and as water
resistance may be aected by certain
activities, it is recommended that you:
- have the watch's water resistance
checked by an authorised Jaeger-
LeCoultre retailer at least once every
two years. It is essential to have such
a check carried out each time your
watch is opened, and before any peri-
od in which it is liable to undergo pro-
longed and/or regular immersions.
- check when making the purchase that
the bracelet is suitable for the intended
use.
- avoid subjecting the watch to exces-
sively abrupt temperature changes.
- protect the watch from being dropped
or suering other accidental impacts,

ENGLISH
35
and have the water resistance checked
after any severe impact.
- avoid using the controls, push-piece,
or time-setting crown while under
water, or outside the water, if the
watch is not yet dry after immersion.
- restore the time-setting crown and
the push-pieces to their normal posi-
tions, (or where applicable, close the
compression keys) after every manip-
ulation.
- rinse the watch with fresh water after
use in sea water.
You may use your watch while swim-
ming as long as you do not exceed the
immersion pressure and do not engage
in any water sports that could cause im-
pacts. This watch is not a piece of div-
ing equipment and should not be used
as such. Also, note that leather straps
are not suited for aquatic activities.

“1000 HOURS
CONTROL” TEST
The Jaeger-LeCoultre Manufacture
pays close attention to the quality and
final checks of its watches.
The 1000 Hours Control is a series of
internal qualification tests for each of
the models in our collection, as well as
internal tests on the production of your
watch, which go beyond ocial timing
tests. These tests include checks of
the movement before and after being
cased up in the watch and cover the
whole watch once it has been assem-
bled, in the conditions closest to daily
wear.
The “1000 Hours Control” legend, or the
“” seal engraved on the back of the
watch certifies that each of the mod-
els from our collection has successfully
undergone all of the qualification tests,
and that your watch has successfully
undergone all of the production tests.
These ensure regularity of rate, resist-
ance to variations in temperature and

ENGLISH
37
atmospheric pressure, ability to with-
stand shocks and magnetic fields, as
well as water resistance.

PERPETUAL CALENDAR
The Perpetual Calendar of this Master
Hybris Mechanica Calibre 184 has the
unique feature of being adjustable in
both directions. This means you can
change the date forwards like a tra-
ditional Perpetual Calendar with the
quick corrector or crown, as well as
backwards, in case of an adjustment
error, by using the crown.
The Perpetual Calendar has a mecha-
nism that takes into account the length
of the current month (28, 30 or 31 days),
and counts a February 29th every leap

40
year. The date, day of the week, month
and year are therefore indicated me-
chanically, without the slightest need
for readjustment until 1st March 2100.
All these are interlinked by an ingenious
mechanism: a genuine, entirely mechan-
ical programme. Thus merely changing
the initial date eects the appropriate
changes in all other functions.
Our time measurement is based on the
Gregorian calendar, i.e. a year of 365
days, 5 hours, 48 minutes and 46 sec-
onds, or in decimals, 365.242192 days.
In practice, the yearly excess of just
less than a quarter (0.242192) of a day
is corrected by 29th February in leap
years. The few missing decimals are
then compensated for every 100 years,
by excluding 29th February.
For the sake of greater precision, this
exclusion does not take place when
the number of centuries is divisible by
4. Such is the case in the year 2400
(divisible by 4), which is a regular leap
year. It is therefore only in the year
2100 that the programming of your

ENGLISH
41
perpetual calendar will need to be cor-
rected. Until that date, your watch will
count days, months and decades. On
1st March 2100, the calendar will indi-
cate the 29th February even though the
actual date will be Monday 1st March, as
such a watchmaker will need to adjust
your watch.
MINUTE REPEATER WITH
WESTMINSTER CHIME
Watches with a striking mechanism
occupy a place apart in watchmak-
ing culture. They present watchmak-
ers with a highly delicate challenge:
to obtain the purest sound and most
harmonious melody while still ensuring
reliability and accuracy.
The Master Hybris Mechanica Calibre
184 is the quintessence of Jaeger-
LeCoultre’s watchmaking know-how in
terms of chiming watches.
Activating the unlocking trigger at 9
o’clock will make the retractable push-
piece appear at 8 o’clock, which is
used to trigger the Minute Repeater.

42
This Minute Repeater chimes thanks
to 4 Trebuchet hammers (2 on both
sides, each with a specific function)
which strike the Crystal gongs. The
bottom left hammer chimes the min-
utes, the bottom right hammer chimes
the hours, and the 4 hammers together
create a melody to chime the quarter-
hours that replicates the famous sound
of Big Ben in London.
This Minute Repeater also features a
time-lapse reduction system to opti-
mise the rhythm of the melody.
A TECHNICALLY ACCOMPLISHED
PUSH-PIECE
In order to make the watch even slim-
mer while preserving its high degree of
aesthetic harmony, the minute repeat-
er is activated by a single retractable
push-piece. The Manufacture has ap-
plied for a patent for this device. The
Master Hubris Mechanica Calibre 184
model is thus equipped with a discreet
unlocking button positioned at nine
o'clock. Activating this brings out the

ENGLISH
43
retractable push-piece at 8 o’clock,
which is used to trigger the Minute Re-
peater. As soon as the Minute Repeat-
er has been triggered, the push-piece
returns to its initial recessed position,
thus ensuring that the watch’s bal-
anced, harmonious appearance is not
disrupted.
The discretion, user-friendliness, and
technical sophistication of this ingen-
ious innovation are not the retractable
push-piece's only advantages. Unlike
traditional triggers used to activate a
Minute Repeater function, for which the
length of travel along a slide may vary
depending on the number of strikes to
be made, in this mechanism the push-
piece's constant travel distance of just
3.5 mm is enough to both wind the bar-
rel and trigger the minute repeater.

To ensure good operating accuracy, it is
advisable to wind your watch regularly.
WINDING
Crown in position 0
The watch is wound by turning the
crown clockwise. The movement is fully
wound when the crown is locked.
Do not attempt to wind a manually
wound watch beyond the locking point.
To ensure good operating accuracy,
it is advisable to wind your watch reg-
ularly.
SETTING THE HOURS
AND MINUTES
Pull the crown out to position 1.
Turn the crown clockwise to move the
hands forward.
The jumping minute hand ensures a very
accurate display of the minute in front of
the corresponding hour-marker.
When the operation is complete, push
the crown back to position 0.

46
NB: If the watch has stopped, the min-
ute hand may be slightly oset from the
hour-marker. When the movement is
wound, it will immediately reposition it-
self in front of the correct hour-marker.
Be careful not to change the time when
the minute repeater is activated.
SIMULTANEOUS ADJUSTMENT
OF THE CALENDAR (DAY, DATE,
MONTH AND YEAR)
This operation is entirely controlled by
a single corrector located between the
lugs at 12 o’clock, which can be oper-
ated via the corrector tool supplied
with the watch. Each press of the tool
moves the calendar one day forward.
Therefore all you need to do is to set
the initial calendar by pressing the cor-
rector until the corresponding date and
month are displayed, to ensure that the
day, date, month and year programme
run correctly thereafter.
