BREMONT AC II
AUTOMATIC CHRONOMETER
Your Bremont watch shows you the time in hours, minutes and seconds,
and the date. With the chronograph you can measure up to 30 minutes in
seconds and minutes. The mechanical movement with automatic winding
has a free-swinging rotor that keeps the mainspring wound via the motion
of your wrist. The movement in your BREMONT AC II has 28 jewels, runs at
28,800 bph and has a 42-hour power reserve once fully wound. The watch
is water resistant to 100m (10ATM) and the dial is protected by a dual anti-
reflective sapphire crystal that is retained securely in the case.
To ensure that this rather special watch continues to run beautifully for
years to come you must follow a few important operating instructions...
WINdING THE WATCH
Your BREMONT AC II can be wound from crown position
I
by rotating
the crown in a clockwise motion. The movement will automatically start
with just a few revolutions of the rotor, however it is better to wind the
movement fully with 30-40 revolutions of the crown. By doing this you
will achieve maximum accuracy and have a power reserve of 42-hours,
even when the watch is not on your wrist.
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.
