When people hear the name Ulysse Nardin they instantly think about the Marine chronometers, the manufacturer is most famous for. But Ulysse Nardin also has a past with astronomical watches. For instance, between the mid-80s and the mid-90s three models named after three big astronomers (Galilei, Copernicus and Kepler) hit the market. And this year, Ulysse Nardin presents a new, exciting and exceptional astronomical watch, the Executive Moonstruck Worldtimer.
Honestly, astronomical complications in watches are not really necessary, whether they show celestial charts, the tides or just the moon phases. But it can’t be denied that mankind has been fascinated with the movement of the celestial bodies since the beginning of time. And the appeal doesn’t decline the more we know about the universe, it is unabated – which also applies for wristwatches that feature astronomical functions.
The Moonstruck Worldtimer recreates the moon’s orbit and the apparent movement of the sun around the globe. Its celestial ballet, just as seen from the Earth, is unlike anything an astronomical watch has previously offered.
Eight years after the first Moonstruck made its mark, the Moonstruck Worldtimer remains the only astronomical wristwatch with the bright part of the moon always facing the sun, as happens in real life.
In the center of the dial, the Northern Hemisphere is depicted as seen above the North Pole. 6 o’clock in London represents the Greenwich meridian, marking Greenwich Mean Time. Three concentric discs turn around this fixed map of the world. The outer circle features a symbol representing the sun. This solar disc, which completes one revolution in 24 hours, also sweeps over a display of 24 time zones and is equipped with a day/night indicator. These markings control the Worldtimer function, allowing the wearer to simultaneously display the time in the 24 cities inscribed on the internal flange.
As for the moon, this appears on a lower orbit. Two discs work together here: on top, the first functions as a circular window showing the position of the Earth’s satellite; below, the second disc, in gold, shows the changing phases of the moon. And with a very high precision – the time lag for each lunar month is just 5.7 seconds per day. Which is one day in 40 years.
The dial also displays a easy-to-read map of the tides, as well as a date function on a track encircling the world map.
It is obvious, that a display this intuitive and has to hide a sophisticated mechanism. The self-winding calibre UN-106 housed in the Moonstruck Worldtimer was entirely designed and produced in-house by Ulysse Nardin. It works at a frequency of 4 Hz and provides a power reserve of 50 hours.
Push buttons at 8 and 10 o’clock enable the wearer to quickly move the time forward or backward by one hour. This feature comes in handy while travelling or when switching to summer time and it doesn’t affect the moon phases.
Parts of the movement can be seen through the sapphire crystal case back.
The Ulysse Nardin Executive Moonstruck Worldtimer is a limited edition of only 100 pieces. The watch is available in platinum or rosé gold. The case has a diameter of 46 millimeters and is water-resistant up to 10 atm. All models are accompanied by a leather bracelet.
In terms of price: these pieces won’t come cheap. The rosé gold models are priced at 75.000€, the platinum ones 95.000€.
