MAINTENANCE
Your B
r e It LIn g
chronometer is a sophisticated instrument which is con-
stantly subjected to a wide variety of stresses and strains. Within a very
small volume, a large number of components contribute to handling all the
functions. t heir mechanical action inevitably leads to a certain amount of
wear and tear, which may be controlled by maintenance consisting of renew -
ing the lubrication and replacing worn components. Like any precision
measurement instrument, your watch must be regularly maintained in
order to function at its highest level of potential: we recommend a regular
service every two years, while the complete overhaul should be scheduled
about every five years. Your authorized B
r e It LIn g
dealer will be pleased to
handle this for you.
WATER-RESISTANCE
t he movement of your chronometer is protected by a sophisticated case fitted
with water-resistance gaskets. Under the influence of certain external factors
such as perspiration, cosmetics, perfumes or dust, these gaskets progressively
deteriorate and must be periodically replaced, ideally every two years.
Moreover, we recommend an annual water-resistance test, which takes only
a few minutes, performed by your authorized B
r e It LIn g
agent.

SUN COMPASS
Your B
r e It LIn g
chronometer may be used as a sun compass, thus enabling
you to determine the n ortherly-Southerly direction. For regions that have
instated daylight saving time, subtract one hour when directing the watch.
In the Northern hemisphere
Point the hour hand precisely towards the sun. In relation
to the watch dial, the point located midway between
the current time and 12 o’clock indicates the South, the
n orth being exactly opposite.
In the Southern hemisphere
Point the hour-marker located at 12 o’clock on the dial
precisely towards the sun. In relation to the watch dial,
the point located midway between the current time and
12 o’clock indicates the n orth, the South being exactly
opposite.
