Time on your side

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.

C7 Rosso Corsa COSC Limited Edition
After months, sometimes years, of developing a watch, it’s a hugely
gratifying feeling when your customers immediately connect with a
new release.
So when the rst iteration of our C7 Rapide Day Date COSC Limited
Edition raced out of our stockroom at a rate similar to that of an F1
car hitting top speed, we knew we had to produce another – and this
time, we had an idea that would create a watch just as special as its
predecessor.
Following in the footsteps of an earlier CW classic, this new 200-piece
Day Date emerges from its paint workshop decorated in Rosso Corsa,
or Italian Racing Red, colours. Initially selected by an early form of
the FIA (International Automobile Federation) as Italy’s national
racing colour in the 1920s, Rosso Corsa has become ingrained in
popular culture as being synonymous with the output of legendary
companies including Alfa Romeo, Maserati and Ferrari.
It’s the perfect addition to any motorsport watch, but in this C7,
it makes even more sense. With its dial and bezel both resplendent
in this rich red hue – a throwback to our C70 Rosso Corsa 1921
Chronometer, whose dial colour drew such praise it became
our foundation going forward – they perfectly match the matte
aluminium case band present as part of our Rapide Collection’s
striking four-piece case.
Inside the Rosso Corsa, an ETA 2836 movement provides a titular
day date complication, as well as chronometer-certied timekeeping
present in only 6% of all Swiss-made watches. In a lifestyle where
looking good is just as crucial as what features under the bonnet,
the C7 Rosso Corsa COSC Limited Edition is a watch that excels on
all levels.

How to operate your C7 Rosso Corsa COSC Limited Edition
PLEASE NOTE: The crown should always be pushed in after
adjustment, and it is best to do so from position 3 to avoid
advancing beyond the desired date. For precise time setting
it is recommended to pass beyond the desired minute and
to set the hand backwards.

. This position is
used for handsetting and stopping of the
second hand.
For a superior water resistance your crown is
of the screw-in type. The crown should sit
ush to the case (position 1) in order to
maintain water resistance.
• First unscrew the crown anti-clockwise from
the case to position 2for winding in power.
Wind in a clockwise direction to re-power
the watch. Your C7 Rosso Corsa COSC
has a maximum power reserve of 38 hours
when fully wound. After a period of non-

emphasis on the quality of our straps as
we do our watches. We only use the nest

pins also included for your convenience.
The following guidelines explain how
easy it is to use, adjust and replace your
Christopher Ward strap.
How to operate your C7 Rosso Corsa COSC Limited Edition

Pull the pin to the side to detach your strap.
2. To reattach your strap, align the pins to the
lug holes and click the strap into position.

Water resistance
Although your watch has been through vigorous static pressure
testing, it is worth remembering that there are many variables
that can aect 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 eect 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.
