C60 Trident Pro COSC Limited Edition
Let’s be clear about this; whatever model
you opt for, the C60 Trident Pro is no
ordinary watch.
The summer of 2017 marks the release of this special
Trident. Limited to just 100 pieces, the Pro COSC
Limited Edition features a striking monochrome
look, while our famous Trident second hand
counterbalance has been nished in red. This touch
of colour also appears with an inverted triangle inset
into the fully-tracked bezel at 12 o’clock.
As part of a collection named after the trident of
Poseidon, the wave guilloche design applied to the
COSC Limited Edition’s dial is suitably oceanic, while
its water resistance down to 600m is appropriate
for a watch inspired by the Greek god of the sea.
Inside, a chronometer-certied SW200 movement
keeps the Trident running with a level of precision
rarely seen throughout most Swiss watches – only
6% receive COSC (Contrôle Ociel Suisse des
Chronomètres) status. It’s a level of accuracy that
shouldn’t surprise when you consider the excellence
of materials and engineering involved in this watch.

How to operate your C60 Trident Pro COSC LE
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
2
for winding in power. Wind in
a clockwise direction to re-power the watch.
Your C60 Trident Pro COSC has a maximum
power reserve of 38 hours when fully wound.
After a period of non-use, we recommend
manually winding the watch to ensure the rotor
weight sustains the amount of power in the
mainspring whilst worn on your wrist – this can
be done via twenty full revolutions of the crown.
• 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 second hand.
For precise time setting it is recommended to
pass beyond the desired minute and to set the
hand backwards.
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 3 to
avoid advancing beyond the desired date.
You must always ensure the crown is fully
tightened before any use in water.

The bezel
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.
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.

Straps and bracelets
As you would expect, we place as much
emphasis on the quality of our straps and
bracelets as we do our watches. We only use
the nest leathers for our straps. Similarly, we
only use the nest metals in the construction
of our bracelets, all of which are precision
engineered for durability, eciency and comfort.
The following guidelines explain how easy
it is to use and adjust your Christopher Ward
strap or bracelet.
Using the quick-release pins on
your strap
1. Locate the quick-release pin on your
strap. 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. Repeat for the other side.
