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 #tide
The sea has been an inspiration to horologists for millennia.
From John Harrison’s marine chronometers to the rst dive watches
of the 1930s, reliable – and water-resistant – timing has always been
an indispensable part of marine life.
And few watches are more steeped with the spirit of the ocean than
your beautiful C60 #tide.
Not only is it a precision-engineered diving instrument that
will function at depths of up to 600m, but it also has a direct
relationship with the sea.
And one sea in particular.
Thailand’s Andaman Sea is home to the various sea-faring tribes,
including the nomadic Moken people. In the past, they were
shermen. Today, because of overshing, that’s no longer possible.
Instead, they ‘sh’ for plastic, which is converted into a robust
yarn or a mouldable material by #tide, a social enterprise. Your
C60 #tide carries the plastic in a ring of injection-moulded #tide
ocean material on the caseback (while the yarn is used in our #tide
straps). You’ll nd a miniature tide mark on the crown too.
While your watch will no doubt receive its fair share of compliments
– you can thank us by email or telephone – the fact it’s helping the
indigenous people of the Andaman Sea will give you a glow every bit
as powerful as that found on its mesmerising luminescent dial.

How to operate your C60 #tide
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 #tide 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 3. For rapid date correction, turn in a
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 #tide
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 10.08am.
However the bezel marker is at the 12.00 hr position.
• Move the bezel marker anti-clockwise so that it aligns with the
8 minute position.
• You can now read that the 55 minute no decompression limit
will occur at 3 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.
