Ulysse Nardin has given the Blast Moonstruck a warmer and more theatrical setting with a new rose-gold limited edition. The watch is the 1065-400LE-2A-BLACK/1A, a 45 mm Blast-family astronomical piece listed by the brand as a 20-piece limited edition.
The story here is not simply a precious-metal case. Blast Moonstruck is Ulysse Nardin’s contemporary route back to the kind of astronomical watchmaking associated with Dr. Ludwig Oechslin and the brand’s Trilogy of Time. In this version, rose gold frames a black architectural display that combines lunar, tidal and world-time information in one dial-side system.
What launched
The official product page describes the case as titanium and 18 ct gold with sapphire glass, and presents the watch as a new Blast Moonstruck interpretation in rose gold. The architecture is deliberately high-contrast: warm gold case structures, black dial rings and an aventurine-like night-sky surface under the central geocentric display.
At the centre is a representation of the Northern Hemisphere viewed from the North Pole. Around it, the watch tracks the moon phase, the days of the lunar month, tidal coefficients, world time, dual time and the positions of the sun and moon around the globe. That is a lot of information, but the point of the Moonstruck format is that these indications are visually connected rather than scattered into isolated sub-dials.
The UN-106 calibre
Inside is the automatic UN-106, a manufacture calibre with 338 components, 42 jewels, a 4 Hz frequency and 50 hours of power reserve. Ulysse Nardin also specifies a silicon escapement, a detail that ties the watch back to the brand’s long-running silicon narrative.
Functionally, the UN-106 is carrying much more than conventional timekeeping. The official functions list includes hours, minutes, date, moon phase, lunar month, tides, worldtimer, dual time and solar/lunar positioning around the globe. For collectors, that makes this less a decorative precious-metal edition and more a compact statement of the brand’s astronomical identity.
Why it matters
Ulysse Nardin has always been most convincing when it lets technical watchmaking look a little strange. The Blast Moonstruck does exactly that. It is not trying to be a discreet travel watch or a classical moonphase; it is a large, openly complex astronomical object that happens to tell local time as part of a wider mechanical map.
The rose-gold execution also lands at an interesting point in the market. Many high-end complicated watches lean either very traditional or very futuristic. This one does both: it references historical astronomical watchmaking while using the aggressive Blast case language to avoid nostalgia.
Horomag take
The new Blast Moonstruck is not a broad-audience release, and that is exactly why it works. At 20 pieces, it is a collector-facing reminder that Ulysse Nardin’s strongest lane is not safe luxury but ambitious mechanical storytelling. The rose gold makes the watch richer and more legible as an object, while the black geocentric display keeps the sci-fi edge intact.
