Your Christopher Ward watch has been designed
and engineered by experts to ensure not only precise
timekeeping, but also to give you a sense of pride
whenever you wear it.
You’ve made an investment, a good one, and the
aim of this handbook is to help you make the most of
it during what I hope will be a lifetime of ownership.

C8 Power Reserve Chronometer
C8 Power Reserve
When our Calibre SH21 movement was
launched in 2014, its designer, Johannes
Jahnke, promised that it would provide a
canvas for him to experiment with further
innovations and complications. The new
C8 Power Reserve Chronometer shows
this has now become a reality.
With its DLC (diamond-like carbon) black case and
dial, highly legible indexes and Arabic numerals, the
C8 PR COSC carries with it many of the design cues
of famous aviation timepieces like the Smith’s Mark II
A clock found in the Spitre. In truth, it feels more like
a timing instrument than regular watch.
The hand-wound version of our own movement
is every bit as impressive as its automatic sibling.
Thanks to its twin barrels, when fully wound, it'll
deliver an incredible ve days of power.
Like the self-winding version of Calibre SH21,
chronometer status is standard, while a power
reserve complication – as promised in the name
of the watch – counts down the time until the
next wind.

How to operate your C8 Power Reserve
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
until the power reserve indicator shows 100%
power.
• Pull gently into position
2 . For rapid date
correction, turn in an anti-clockwise direction.
• To set the time pull out the crown gently into
position
3 . This position is used for handsetting
and stopping of the second hand. Turn the crown
until you reach the correct time e.g. 10.08 hr.
For precise time setting it is recommended you
pass beyond the desired minute and to set the
hand backwards.
PLEASE NOTE: As this watch uses a manually
wound mechanical movement, take care
not to overwind the crown past the point of
resistance as it will damage the movement.
Date correction should not be carried out
between 20.00 hr and 02.00 hr as the watch
gearing will already be aligning itself to
change the date.

How to operate your C8 Power Reserve
The power reserve function
The power reserve indicator shows the winding
status of the main spring.
• When the hand is in position A , the
movement is close to stopping. The watch
should therefore be wound manually to
obtain a maximum power reserve.
• When the hand is in position
B , the watch
is at its maximum winding position.
Take care not to overwind the crown past
the point of resistance as it will damage
the movement.

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.
1 ATM (10 metres)
Safe to wear your watch while
washing your hands with tap water.
3 ATM (30 metres)
Washing your car and/or
general hose pipe usage.
5 ATM (50 metres)
Water resistant to most
household shower units.
15 ATM (150 metres)
Safe to use while snorkelling
in open water.
30 ATM (300 metres)
Ideal for experienced divers and
those practising scuba-diving.
50 ATM (500 metres)
Professional divers, experiencing
prolonged exposure underwater.
100 ATM (1000 metres)
Professional deep sea diving.
