Jaeger-leCoultre Master Hometime User Manual

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 observe significant irregular running of
your watch, you are advised to take it to an authorised Jaeger‑
LeCoultre retailer, who will make any necessary adjustments.
Quartz models
Quartz models are accurate within two to three minutes per
year.
Jaeger‑LeCoultre quartz watches contain a battery
and electronic components. In a service 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 short swims or when diving
in from the edge, but not from a diving board. Nor should it
be used for undersea diving or for sports 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.
