Ulysse Nardin - Moonstruck Worldtimer

The Ulysse Nardin Moonstruck Worldtimer is the only watch to depict the movements of the moon and sun in relation to the Earth together with a map of the tides.

Available in a 46 mm rose gold or platinum case, this new model recreates the moon’s orbit and the apparent movement of the sun around the globe as they are seen from the Earth.

The intuitive display hides a sophisticated mechanism that provides a highly accurate indication of the phases of the moon.

In the centre of the dial, the Northern Hemisphere is depicted as seen from above the North Pole. Six o’clock in London represents the Greenwich meridian, marking the Greenwich Mean Time (GMT).

Three concentric discs turn around this fixed map of the world. The outermost 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.

The moon 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. By separating this unique display into two rotating parts, Ulysse Nardin has accomplished such a high level of precision that the time lag for each lunar month is just 5.7 seconds per day, or one day in 40 years.

The dial also displays a particularly easy-to-read map of the tides, which is the result of the gravitational forces of these two celestial bodies, as well as of the centrifugal force exerted by the rotation of the Earth.

Equipped with silicium technology, and entirely designed and produced in-house, the self-winding calibre UN-106 housed in the Moonstruck Worldtimer also offers a date function, on a track encircling the world map. Beating at 28,800 vibrations per hour, it has an autonomy of 50 hours.

The push buttons at 8 and 10 o’clock enable the wearer to quickly move the time forward or backward by one hour.

Water resistant to 100 metres / 330 feet thanks to its screw down security crown, the Ulysse Nardin Moonstruck Worldtimer has a price of Swiss Francs 75,000 in rose gold (ref. 1062-113/01) or Swiss Francs 95,000 in platinum (ref. 1069-113/01). Only 100 pieces will be produced. ulysse-nardin.com
