like to congratulate you most
sincerely on your purchase of a
Bremont timepiece.

cater for those that demand more
out of their mechanical watch. Our
aim has always been to produce
beautifully engineered timepieces
of exceptional quality that will last
several lifetimes, and ones that feel
particularly special when placed on
the wrist.

AUTOMATIC CHRONOMETER
Your Bremont watch shows you the time in hours, minutes and seconds,
and the date. 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 Broadsword has 31 jewels, runs at 28,800
bph and has a 38-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 Broadsword 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 revolutions of the crown. By doing this you will
achieve maximum accuracy and have a power reserve of 38-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 to ISO 3159 standard and
accompanied by a performance certificate 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 registration card to Bremont to
register your watch and validate your warranty.
The chronometer testing, 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.
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 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.
SERVICING
Every part of your watch has been carefully chosen from the best
selection of materials available. In spite of this, a number of parts will
always be subject to natural wear. It is therefore important that these
