C9 MOONPHASE
C9 MOONPHASE
Humans have looked to the moon as a device
for telling the time for some 34,000 years.
Today, what we know as a year consists of
12 calendar months, with eight lunar cycles
(or “phases of the moon”) of 29.5 days –
29.5306 days exactly, for the pernickety
among you – the time elapsed from one full
moon to the next.
Breguet introduced the first wrist watch with a moon
phase complication, the Perpetual Calendar
No. 4244, in 1929 and it wasn’t long before the
big names in haute horlogerie such as Patek
Philippe and Audemars Piguet followed with
their own interpretations. And now, we are proud
to introduce the first ever Christopher Ward
moonphase watch, created by our own
master watchmaker, Johannes Jahnke.
With his Calibre JJ04, Johannes modified the
base ETA 2836-2 by creating two gear systems
incorporating four wheels to drive the moon disc,
and a further two wheels for the setting mechanism.
The result is a smooth and continuous movement
of the moon disc, in synch with the minutes and
hours – the norm for moonphase watches is that
the disc jumps once a day leaving the moon
inaccurate for several hours each day. Once set,
the representation of the moon’s phase at any
particular moment is unerringly precise. Additionally,
the new gearing means that the moon disc is also
accurate to within one day every 128 years of the
base movement’s accuracy.
If the C9 Moonphase is an astronomically precise
watch, it is also a very beautiful one. Within the
perfectly sized and hand-finished 40mm case and
beneath a domed sapphire crystal is perhaps our
finest dial to date, displaying through a wide curved
aperture a generously-cut moon disc, allowing the

33
increments of the moon’s stately and accurate
passage through the skies to be admired in detail.
Onto the large moon disc, the moon’s surface
is 3D stamped and given a semi-matt galvanic
finish, revealing its texture to full effect. The bespoke
guilloche pattern on the lower half of the centre
dial is inspired by the tidal patterns the moon’s
gravitational pull determines, and when taken
together with the polished nickel hands and
indexes, the overall effect is quite magnificent.
The complication most requested by our followers
since CW was founded in 2004, in the C9
Moonphase we have created a timepiece that
fulfils ours and our customers’ common desire,
but also one that, hopefully, does credit to the
source of its inspiration, our waxing, waning,
wondrous moon.

HOW TO OPERATE YOUR C9 MOONPHASE
SETTING THE TIME/DATE
• Position
1
is for winding in power.
Wind in a clockwise direction to re-power
the watch.
• Pull gently into position
2
. For rapid date
correction, turn in a clockwise direction.
• Pull gently into position
3
. This position
is used for handsetting, and stopping of
the second hand.
PLEASE NOTE: The date should not be
changed during the date changing
phase between 20.00 hrs and 02.00 hrs
as the watch gearing will already be aligning
itself to change the date.

RAPID ADJUSTMENT OF THE MOON PHASE
Setting the moon phase is relatively simple.
For perfect synchronization, adjustment of the
moon phase must be done after setting the
current time and date. You will also need the
date of the last full or new moon.
• To adjust the moon phase pull gently
into position
2
. Turn in an anti-clockwise
direction to rotate the moonphase disk
into the desired position.
PLEASE NOTE: Rapid correction of the moon
phase is possible at any time without risk of
damaging the mechanism.
