Time on your side
Your Christopher Ward watch has been designed in Britain

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.

C65 Dartmouth Series 1
Gaze upon the C65 Dartmouth and you’ll sense a depth of nautical
history owing through it.
CW’s rst watch carrying the Naval crown insignia of the Royal Navy
that can be sold to the general public – a feature made possible
thanks to an ocial licence from the UK’s Ministry of Defence – the
C65 takes its name from Britannia Royal Naval College based in the
South Devon town of Dartmouth.
Yet those with a keen horological eye may well recognise some of the
C65’s distinguishing ourishes from elsewhere. Inspired by the Omega
Seamaster 300 ‘Big Triangle’ – initially known as the Royal Navy 0552,
a Ministry of Defence-approved piece that saw the rst appearance
of the popular inverted triangle later exported to civilian versions –
the Dartmouth features an inverted ‘wedge’ and tapering indexes
at 12 o’clock; all have been lled with white T-C1 or Old Radium
Super-LumiNova®for excellent legibility.
As the ‘Big Triangle’ entered service in 1967, it’s apt the Dartmouth
sits within the C65 family, a collection that combines lithe ‘60s dive
visuals with today’s engineering prowess. Powered by a chronometer-
certied movement, the C65 is accurate to just seconds per day –
but what else would you expect from a watch bearing the crown of
the United Kingdom’s Naval Service?

Setting the time and date
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 C65 Dartmouth Series 1 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. 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.

Diving with your watch
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.
