Suspended Earth, Eternal Moon: The Blast Moonstruck in Rose Gold

Since 1846, Ulysse Nardin has challenged convention, transforming horology into a dialogue between science and art. The Manufacture’s legacy of astronomical watchmaking — from nineteenth‑century moonphase instruments to Dr. Ludwig Oechslin’s legendary Trilogy of Time — has always sought to translate the cosmos into mechanical poetry. Today, that lineage continues with the Blast Moonstruck, a rose gold limited edition of just 20 pieces, conceived as one of the most sophisticated astronomical complications ever created.

The Blast Moonstruck embodies Oechslin’s principle: complexity belongs in the movement, not in the reading. Powered by the calibre UN‑106, the watch integrates five astronomical indications into a single geocentric display:

High‑precision moonphase accurate for 40.3 years.
Days of the lunar month and tidal coefficients.
Worldtimer with patented time‑setting.
Positions of the Sun and Moon around the globe.

At the centre lies a suspended three‑dimensional Northern Hemisphere, engraved beneath a domed sapphire glass box. Around it, the Sun indication rotates on a 24‑hour disc, aligning with world time zones, while the Moon follows its orbital path, faithfully oriented so its illuminated portion always faces the Sun. The tidal coefficient display completes the celestial model, echoing Ulysse Nardin’s maritime heritage.

“The illuminated portion of the Moon continuously faces the Sun, exactly as it does in nature.”

Architecture & Craftsmanship: The 45 mm case combines rose gold with black DLC‑treated titanium, its layered geometry catching light across satin, polished, and laser‑finished facets. Beneath the sapphire dome, an aventurine dial shimmers like a star‑filled sky, framed by a rose gold ring engraved with the days of the month. The watch is secured by a black alligator strap with folding clasp, balancing technical innovation with elegance.

Produced in only 20 examples worldwide, the Blast Moonstruck is more than a timepiece — it is a celestial instrument, a wearable planetarium that distils centuries of astronomical calculation into a glance. In its suspended Earth and eternal Moon, Ulysse Nardin celebrates 180 years of challenging convention, and the enduring human desire to measure, understand, and carry the cosmos on the wrist.
