Van Cleef & Arpels has spent well over a hundred years gazing skyward, and it shows no signs of stopping. The Maison has always treated the cosmos less as a science lesson and more as a love story—one told through gemstones and guilloché, and now, one of the standout pieces at Watches and Wonders 2026: The Midnight Jour Nuit Phase de Lune, is part of this year’s “Poetry of the Heavens” collection.
Just like every other Poetic Complication the Maison has created, this isn’t really “just” a watch; it’s high jewellery that happens to tell the time. At Van Cleef & Arpels, the mechanics have always taken a back seat to the storytelling—poetry first, horology second, though just as much research and development goes into the engineering as into the emotion. This latest release builds on the Jour Nuit collection (first launched in 2008, refreshed in 2024), turning its attention to the Moon, a muse the house has returned to again and again since 1929, when lunar complications first entered its watchmaking history via a moonphase pocket watch.
Beneath the poetry sits real engineering: a 42mm white gold case, a one-of-a-kind black Murano aventurine dial, and a pusher that sets the whole thing spinning to reveal the moon whenever you fancy. Press the button on the case rim, and an automaton reveals the current moon phase on demand—even when the moon is tucked away. The dial spins a full 360 degrees over roughly ten seconds, unveiling the moon in its full starlit glory. It took four years for Van Cleef & Arpels’ Watchmaking Workshops in Geneva to bring this astronomical choreography to life.
As Rainer Bernard, the house’s Watchmaking Research and Development Director, puts it: getting the on-demand animation right was no small feat. The discs needed to complete an extra full rotation without throwing off the accuracy of the moon phase. What the Maison really wants is you feeling something as you watch the sun and moon glide across the dial.
On the top, that shimmering black “sky” plays host to a 24-hour day/night cycle. A guilloché-embellished yellow-gold sun on one side, a mother-of-pearl moon surrounded by a scatter of tiny stars on the other. Underneath, a rotating 24-hour disc handles the day/night choreography, while a separate lunar disc ticks along on its own rhythm—24 hours, 16 minutes and 27 seconds—precisely calibrated to track the Moon’s real 29.5-day cycle. The two systems are choreographed so the sun and moon rise and dip behind a guilloché horizon like clockwork in theatre.
What’s undeniable here is the sheer ambition packed into one case. You’ve got two complications working in tandem purely to serve a single visual moment: a dial material developed entirely in-house and a case back that reimagines the cosmic view where it’s not Earth looking up at the Moon, but the Moon looking back at Earth. An engraving of the lunar surface wraps the case back, while a miniature enamelled Earth sits on the sapphire crystal above the oscillating weight. It’s the kind of twist you’d expect from a maison that thinks several steps ahead. Proof that once again, for Van Cleef & Arpels, the best complications are the ones that feel like magic rather than machinery.
