MAINTENANCE
Your B
reitling
chronometer is a sophisticated instrument which is
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
reitling
dealer will be pleased to
handle this for you.
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

RIDER-TAB BEZEL
the bezel of your watch is fitted with 4 hour-markers called
rider-tabs: they are used as points of reference to mark the
time of departure or a limit time one wishes to remember.
on models with no chronograph functions, they also serve
as “minute chrono graph” enabling one to measure time
elapsed in minutes.
rider-tabs make it easier to rotate the bezel by giving a bet-
ter grip (especially when wearing gloves) and additionally
protect the glass.
BATTERY END-OF-LIFE INDICATOR (EOL)
this watch’s movement includes a battery end-of-life (eol) warning system,
signalled by the digital readout’s flashing mode. the battery must be replaced
within the next few days by an authorized B
reitling
agent. also ask for a
water-resistance test to be performed on the watch.
