Now in two striking sizes, the C1 Moonphase brings the beauty of an aventurine dial to every wrist. The classic 40mm offers maximum dial presence, while the new 37mm distils our Light-catcher™ case into a more compact fit. Two ways to wear the night sky—both unmistakably Christopher Ward.

Crazy about the detail
A dial made from aventurine, a glass infused with reflective flakes of copper oxide that resemble the starry night sky. And because every piece of aventurine is different, each watch is unique.


Lunar tick
Two luminous, 3D moons 25 percent bigger and brighter than on our previous moonphase – and even more accurate in appearance. Constructed in Globolight XP©,a ceramic-Super-LumiNova mix which allows for intricate sculpting.

“Moonphase is the perfect combination of art, craft and science”
Here, our model Amy wears the smaller
C1 Moonphase 37 on her 5.5 inch wrist.

Clarity from every angle
The box sapphire crystal delivers improved clarity, an authentic retro aesthetic and a raised side profile – thanks to its 4.5mm thickness.

Welcome to the dark side
Flip Moonphase over to see the movement through the sapphire caseback, which enables the watch to follow every phase of the moon accurately for 128 years.
Perpetual lunacy
At the heart of the ultra-wearable C1 Moonphase is JJ04, CW’s ingenious modular movement, which follows the actual moon in real time. Combine with the aventurine glass dial– and a textured Globolight©‘moon’ that’s one of the brightest in watchmaking.
