Introduction
Congratulations on the purchase of your Jaeger‑LeCoultre
watch, and thank you for your confidence.
Designed for men criss‑crossing multiple time‑zones on a
daily basis, the Master Hometime watch features a travel time‑
zone display function tracking the time in another part of the
world, without affecting the minute hand and complete with
a date correction function. A second hand indicates the zone
of origin time, while driving its associated day/night indicator.
Please check out the operating instructions for your Jaeger‑
LeCoultre timepieces: we hope that you will be very happy
with it.
Accuracy
Manual or automatic winding mechanical models
The accuracy of the mechanical movement watch models
is determined by the balance. The latter performs 21,600 or
28,800 vibrations per hour, depending on the model (see
technical specifications applicable to each model).
Despite all the care with which the Manufacture Jaeger‑
LeCoultre master watchmakers have made and assembled
your watch, its accuracy is subject to the influence of gravity,
magnetic fields, impacts and ageing of the oils. Watch accuracy
is measured by rate regularity in a variety of positions.
The nature of your constitution or lifestyle may lead to slight
irregularities. If you obser ve significant irregular running of
your watch, you are advised to take it to an authorised Jaeger‑
LeCoultre retailer, who will make any necessary adjustments.
Quar tz models
Quartz models are accurate within two to three minutes per
year.
Jaeger‑LeCoultre quar tz watches contain a battery
and electronic components. In a ser vice operation,
your official Jaeger‑LeCoultre Service Centre or your
authorised Jaeger‑LeCoultre retailer will collect and
dispose of them in accordance with current standards.
Water‑resistance
Jaeger‑LeCoultre Master Hometime watches are water‑
resistant to 5 bar/atm. This property can be identified by the
symbol engraved on the case‑back. This means that
you can use your watch during shor t swims or when diving
in from the edge, but not from a diving board. Nor should it
be used for undersea diving or for spor ts where there are
significant risks of hard knocks, such as windsurfing and water‑
skiing. Please also note that leather straps are not suited to
water sports.
Furthermore, it is essential to have your watch’s water‑
resistance checked by an authorised Jaeger‑LeCoultre retailer
at least once every 2 years, and definitely before any period
in which it will undergo prolonged and/or regular immersion.

«1000 Hours Control» test
by Jaeger‑LeCoultre
Jaeger‑LeCoultre subjects each of its watches to the rigourous
“1000 Hours Control” test programme. Unique in its kind,
this programme consists of 1000 hours of comprehensive,
stringent checks.
The “1000 Hours Control” seal or marking affixed or
engraved on the back of your watch certifies that it has
undergone this obser vation programme in our laboratories
and has passed all the tests.These comprise rate regularity
checks, temperature and atmospheric pressure tests, impact
and magnetic field resistance tests, as well as water‑resistance
tests. 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 par t of the movement. Jaeger‑LeCoultre tests not only
the movement before casing it within the watch, but also the
watch as a whole.
Technical specifications
‑ Automatic winding mechanical movement,
Calibre 975H.
‑ 28,800 vibrations/hour.
‑ Power‑reser ve: approximately 48 hours.
Movement
Functions
The Master Hometime watch model features a double set
of hands which enables the local time on the main display
to be changed rapidly by moving the corresponding hand
forward or backward in 1‑hour jumps, while maintaining a
reference time by means of a second hour hand, with a 24‑
hour indicator at 12 o’clock. The watch offers the following
functions:
‑ Rapid, independent 2‑way local time adjustment (travel
time‑zone).
‑ Date synchronised with local time; 2‑way adjustment.
‑ Reference time (blue hand).
‑ 24‑hour indicator linked to the reference time.
‑ Minute and small seconds.
Given these functions, if you display a local time identical to
the reference time, the two hour hands will be superimposed.
You may use the local time and reference time displays as you
wish, for example:
‑ Indicate the same time in the local time display and
reference time display; the two hands will then be
superimposed, offering a classic display.
‑ Set a different time on the main display while keeping the
reference time on the additional hand (blue hand).
‑ Set another time‑zone on the reference time display.
‑ Indicate the official GMT time on the reference time
display, so as to deduce the time in any time‑zone based
on its difference relative to GMT time, and then display it
on the local hands.
Whichever option you choose, the local time function enables
you to move the hour hand of the main display rapidly in
1‑hour jumps, in either direction, simultaneously driving the
date.
This mechanism thus enables you to set a different time in
a few steps, without losing the accuracy of the minute and
seconds hands. It is very useful when travelling in order to
display the time in the relevant time‑zone, while keeping the
time in the country of origin on the secondary reference
displays.
On returning from your trip, you can restore your home time
to the main display just as quickly.

Use
The crown on the Master Hometime watch enables you to
do the following:
‑ In position 1, wind the watch if it has not been worn for
over 48 hours;
‑ In position 2, set the local time (travel time‑zone) and
date;
‑ In position 3, set the reference time, which drives the
central blue hand and the 12 o’clock counter hand.
Starting the watch
Pull the crown out to position 1.
A few clockwise turns of the crown are enough to set the
watch running. It will then automatically wind up when you
wear it. Please note that the crown does not lock when
winding, even when the watch is fully wound.
Setting the reference time
This setting drives all the functions: reference time, local time,
minute, date and seconds. It firstly enables you to set the
reference time hour hand, and also to make an accurate
minute and seconds setting.
Pull the crown out to position 3.
The movement is then locked (“stop seconds” function). To
enable accurate setting with a time signal, stop the seconds
hand at 60.
Move the reference time hour hand and the minute hand
either way until the desired time, taking into account the 24‑
hour indicator on the counter at 12 o’clock.
Note: during this operation, the local time hour hand is
automatically driven (along with the date), while maintaining
its difference from the reference time; this is normal, so there
is no need to worry about this step!
Upon the time signal, push the crown back into position 1.
The watch starts r unning again.
Setting the local time (main display)
Use and adjusting the date
Pull the crown out to position 2.
You may turn the crown in either direction, as the main hour
hand and the date are driven either forward or backward
depending on the chosen direction. Note that to correct
the date by one day, the local time hand must complete two
revolutions of the dial. The minute hand and the small seconds
hand keep running so as to maintain accurate setting. The hour
hand moves in 1‑hour jumps.
Setting the date
Turn the crown forward or backward (depending on the
closest distance between the indicated date and the desired
date), and turn the hour hand as many times as necessary
until the desired date is displayed.
Setting the local time
After setting the date, move the local time forward or
backward past midnight to display the desired time, in order to
take account of the date indication.
‑ You have turned the crown clockwise: if the date moves
forward when the hands pass midnight, you are moving
into the morning.
‑ You have turned the crown counter‑clockwise: if the date
moves backward when the hands pass midnight, you are
moving back into the evening.
When the operation is completed, push the crown back into
position 1.
