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

)

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

. For rapid date

correction, turn in an anti-clockwise direction.

• To set the time pull out the crown gently into

position

. 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

, 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

, 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.
