BREMONT BOEING MODEL 1 TI-GMT
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 Model 1 Ti-GMT has 21 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 watch has a screw-in crown. The purpose of the screw-in crown is
to protect the watch from penetrating water and to avoid unintentional
adjustment of the time or date. To unscrew the crown, rotate the crown
to the left where it will automatically assume position
I . This position
is also the winding position for the watch, and you can manually wind
the watch by hand. 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 unscrewing the crown and pulling it out to
position
II
. You will now be able to change the date by rotating the crown
anti-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 screwed back in after setting the watch.
This can be achieved by gently pressing the crown down whilst rotating it
in a clockwise direction.
USING THE 24 HOUR HaND
The 24 hour hand allows the wearer to tell the time in an additional time
zone. Before setting the 24 hour hand ensure that the local time is set on
