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
