Perpetual lunacy

At the heart of the ultra-wearable C1 Moonphase 37 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.

Same ’phase, different cases

The new smaller C1 Moonphase 37boasts a 37mm Light-catcher™ casedesigned for the slimmer wrist– ideal for everyone regardless of wrist size. The original C1 Moonphase 40has more ‘real estate’ on the dial for maximum impact.

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.

Two luminous, 3D moons25 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.

Clarity from every angle

The box sapphire crystaldelivers improved clarity, an authentic retro aesthetic and a raised side profile – thanks to its 4.5mm thickness.

“Moonphase is the perfect combination of art, craft and science”

A thin line between genius and insanity

Conceived by Johannes Janke and developed by Frank Stelzer, the power behind the glory is Calibre JJ04, our in-house modular movement.

JJ04 allows the watch’s ‘moon’ to smoothly followthe actual moon’s journey around the sky accurately for 128 years.
