CHROnOMeTeR TesTIng
Your Bremont watch is chronometer tested and accompanied by a performance
certificate issued by the 'Controle Officiel Suisse des Chronometres' (COSC) to
show that the mechanical movement has passed all of the rigorous precision
tests - a necessity of the chronometer designation.
Important notice: 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%.

enjoyment that comes from wearing a Bremont timepiece lasts generations.
We therefore recommend that the following tips for watch care are observed...
