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.

C60 Abyss SH21
The all-black ‘stealth’ watch is a comparatively new addition to the
world of watchmaking.
You have to possess a certain mindset to wear a timepiece that’s
denitely monochrome. That breaks the rules of what a watch
‘should’ look like.
But when you strap it on, you’ll soon notice the dark Trident hands,
smoked sapphire dial and gunmetal indexes are no impediment to
telling the time instantly. And the way the 42mm light-catcher case
sits on the wrist makes wearing it for long periods easy.
With its Trident 3 DNA, your C60 Abyss SH21 is a professional diving
watch, able to function at depths of 600m – something that’ll give
you reassurance whenever you take to water.
Other people may just see a cool black watch, unaware of the elite
Swiss engineering that makes it such a high-powered timepiece.
And that’s ne. Because you don’t do boasting or ‘ash’.
You demand excellence on your terms – no one else’s. Hence your
choice of the C60 Abyss SH21.
Enjoy your adventures together.

How to operate your C60 Abyss SH21
For a superior water resistance your crown is of the screw-down
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 C60 Abyss SH21 has a maximum power reserve of
120 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 3. For rapid date correction, turn in an
anti-clockwise direction.
• Pull gently into position 4. This position is used for handsetting
and stopping of the seconds hand. For precise time setting it is
recommended to pass beyond the desired minute and to set the
hand backwards.

Unscrew and then pull
PLEASE NOTE:
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. The crown should always be pushed in after
adjustment, and it is best to do so from position 3to avoid
advancing beyond the desired date. You must always ensure the
crown is fully tightened before any use in water.

How to operate your C60 Abyss SH21
If using the bezel for a dive and let’s say the recognised maximum
“no-stop time” is 55 minutes, then in this example (shown right)
the time at the surface immediately before the dive is 10.10am.
However the bezel marker is at the 12.00 hr position.
• Move the bezel marker anti-clockwise so that it aligns with the
10 minute position.
• You can now read that the 55 minute no decompression limit
will occur at 5 minutes past the next hour.
Diving with your watch
PLEASE NOTE:
It is always useful and best practice to make a note on a dive slate
before entering the water and to carry a set of dive tables should the
dive plan change during the course of a dive. A safety stop for 3 to 5
minutes at 15ft is recommended at the end of all dives. A safety stop
for 3 minutes at 15ft is required any time you come within 3 pressure
groups of a no decompression limit, and for any dive to a depth of
100ft or deeper.
