Bremont AC-R-TI, Technical Notes

Page: 7 / 51

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...
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.
clEANING
Use warm water followed by a microfibre cloth to clean metal and sapphire.
cROwN
Ensure that the crown is screwed in to prevent entry of water into the
mechanism.
SEA wATER
Wash with fresh water following exposure to saline water.
ShOckS AND JOlTS
Avoid any heavy shocks to the watch.
MAGNETIc FIElDS
Avoid contact with electrical equipment and strong magnets such as speakers,
magnetic tablet case covers and radio alarm clocks.
TEMPERATuRE
Keeping the watch in contact with the wrist will help minimize any exposure
to extremes. Bremont recommend that you do not wear your watch near hot
water, for example in the shower, steam room or jacuzzi. Extreme changes in
temperature can cause moisture to permeate the seals and cause condensation
to form inside of the watch.
chEMIcAlS
Wash with warm fresh water if it is exposed to solvents etc. to avoid damage
to seals and watch straps.
