USING THE WORLd TIMER FUNCTION
When used by travellers, wherever they are in the world, the 24 hour hand
must be set to GMT against the hour markings (1-24) on the Roto-click®
bezel, to do this, pull the crown out to position II and rotate the crown
in an anti-clockwise direction. This must be done with the red triangular
index (London) set at the 12 o' c lock position by rotating the bezel crown.
Once this adjustment is made GMT will be indicated by the 24 hour hand
whenever the red triangular index is returned to the 12 o' c lock position -
the hand must not be adjusted again.
To read off the time at any other location - the location required e.g
Hong Kong is bought to the 12 o' c lock position, the time in Hong Kong can
now be read off directly against the 24 hour hand. Hong Kong time will
be continuously indicated by the 24 hour hand until another location is
placed at the 12 o' c lock position. *WT Function does not apply to daylight
saving.
CHRONOMETER TESTING
Your Bremont watch is chronometer tested and accompanied by a
performance certificate issued by the 'Controle Officiel Suisse des
Chronometeres' (COSC) to show that the mechanical movement has passed
all of the rigorous precision tests - a necessity of the chronometer designation.
All manuals and user guides at all-guides.com
Remember to complete and return the CosC registration card to
Bremont to register your watch and receive your certificate.
The chronometer certification, which takes 15 days to complete over several
different temperature ranges and watch positions, means that the average
daily variation rate will be between -4 and +6 seconds. With 86,400 seconds
in a single day, this gives Bremont' s watches an accuracy of 99.998%.
WATCH CARE
Bremont watches are put through extensive testing before they are
released from the workshop - whether it is for time-keeping precision,
temperature, shock and scratch resistance or pressure testing; all of our
strict tolerances have to be met. Although Bremont watches have more
than proved their resilience before they are released from our workshop,
we want to ensure that the enjoyment that comes from wearing a Bremont
timepiece lasts generations. We therefore recommend that the following
tips for watch care are observed...
CleanIng
Use warm water followed by a microfibre cloth to clean metal and
sapphire.
