Page: 5 / 41

sETTINg ThE dATE
You can adjust the date by pulling out the crown to position II. You will
now be able to change the date by rotating the crown clockwise.
Do not change the date between 20:00 and 03:00
sETTINg ThE TIME
Pull the crown out to position III, this will stop the movement, you can
now position the minute hand exactly. To start the second hand, push the
crown back to position I. When setting the time, it is worth noting that
the date change always takes place at mid-night (00:00). If this change has
already taken place at 12:00 noon, you must move the hands forward by 12
hours. Ensure that the crown is pushed back in after setting the watch.
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.
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.
CRown
Ensure that the crown is pushed in to prevent entry of water into the
mechanism.
sea wateR
Wash with fresh water following exposure to saline water.
