Maintenance; Water-Resistance - Bentley GMT Manual De Instrucciones

MAINTENANCE

Your B chronometer is a sophisticated instrument which is
reItLIng
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 dealer will be pleased to
reItLIng
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
