C60 Atoll 300
Congratulations on the purchase of your C60 Atoll 300.
Named after the atolls of the Indian Ocean, it combines a striking
fumé dial with the elite performance you’d expect of a Christopher
Ward pro dive watch.
And while the Atoll uses the super-slim C60 Trident Pro 300 as its
template, this is a timing instrument with its own personality.
The dial has been carefully lacquered so the colour goes from light to
shade as you move further to the edge. And because details matter,
the date wheel has been colour-matched to the dial.
Everything about your C60 Atoll 300 is made for daily wear: smart
enough for the oce, rugged enough to accompany you on the
deepest of dives (it’s waterproof to 300m). And the decorated
Sellita SW200-1 automatic movement will make sure you’re always
on time.
Of course, the only way to truly connect with your beautiful new
watch is to strap it to your wrist and take it out into the world.
And if you can make it to the Indian Ocean, so much the better.

How to operate your C60 Atoll 300
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 Atoll 300 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 3 to 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 Atoll 300
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.
