Time on your side
Your Christopher Ward watch has been designed in Britain
and engineered in Switzerland by highly talented craftspeople.
This ensures not only accurate and precise timekeeping, but also
brings a real pride of ownership that only watches of the highest
quality standards can hope to deliver.
You have made an investment, a good one, and the aim of this
manual is to help you make the most of that investment in what
we hope will be a lifetime of ownership.

C65 Cranwell Series 1
Built in 1916 and used by the Royal Air Force (RAF) for training
purposes ever since, RAF College Cranwell is also known as the world’s
rst air academy.
Such a stake in history made it the perfect title for the C65 Cranwell,
a watch that, although technically part of the C65 vintage dive
family, wears its aeronautical references proudly. In part, this is
due to it sharing elements with two classic models from the mid-
20th century: the Jaeger-LeCoultre Mark XI and the IWC Mark XI,
specication 6B/346.
Released in 1949, both watches were approved by the UK’s Ministry
of Defence (MOD) following the Second World War to help RAF pilots
improve accuracy during their operations.
It seemed appropriate that, as a brand licensed by the MOD to
produce watches bearing ocial insignia of the UK Armed Forces,
the C65 Cranwell should reference two watches so intrinsically linked
to the RAF. Incorporating similar design ourishes from the originals –
the lumed Arabic numerals and triangle, the white needle-like seconds
hand – alongside modern touches like our elegant ‘light-catcher’
case and the highly-detailed Heraldic badge deep-stamped into its
backplate, the C65 is a perfect fusion of old and new.
And speaking of accuracy: the presence of a Swiss-made
chronometer-certied SW200 movement inside will keep the
C65 Cranwell ying along smoothly!

The crown should sit ush to the case (position 1) in order to
maintain water resistance.
• To re-power the watch after a period of non-use, simply wind
the crown in a clockwise direction. Your C65 Cranwell Series 1
has a maximum power reserve of 38 hours when fully wound.
Normal wearing will allow the rotor to start re-powering the
watch over time after putting on your wrist.
• Pull gently into position 2. This position is used for handsetting
and stopping of the second hand. For precise time setting
it is recommended to pass beyond the desired minute and to
set the hand backwards.

Straps and bracelets
As you would expect, we place as much
emphasis on the quality of our straps and
bracelets as we do our watches. We only
use the nest materials in our straps,
with quick-release pins also included for
your convenience.
The following guidelines explain how easy
it is to use, adjust and replace your
Christopher Ward strap or bracelet.
How to operate your C65 Cranwell Series 1

on your strap (A) or bracelet (B).
Pull the pin(s) inwards to detach.
2. To reattach your strap (C) or bracelet (D),
pull the pin(s) inwards, and align the
spring bars so that they click securely into
the lug holes on each side.

Water resistance
Although your watch has been through vigorous static pressure
testing, it is worth remembering that there are many variables that
can aect the water resistance of your watch. For instance, arm
movements during swimming and the sudden impact of diving
and water sports will drastically increase the pressure the watch
is under.
Wearing your watch in the bath, shower, or sauna can also have
an eect as a rapid increase in temperature can cause seals to
expand and in extreme cases, malfunction or create condensation.
For these reasons, the water resistance rating of your watch
(as shown) should only ever be considered a guideline and we
strongly recommend they are always adhered to.
