SUN COMPASS
Your B
chronometer may be used as a sun compass, thus enabling
reItLIng
you to determine the northerly-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
north 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 north, the South being exactly
opposite.

constantly 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. their 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

WATER-RESISTANCE
the movement of your chronometer is protected by a complex case fitted
with gaskets to ensure its water-resistance. Under the influence of various
external agents – perspiration, chlorinated or salt water, cosmetics, fra-
grances or dust – these gaskets gradually deteriorate and must be regularly
replaced. If used intensively in water, we recommend that this be done
once a year as part of a service. If the watch is only occasionally used in
water, this operation may be carried out every two years. Moreover, a
chronometer is a sophisticated instrument which is
