Dressed in a sleek, ultra-light titanium and ceramic round case measuring 45 mm in diameter and equipped with a skeletonised tourbillon movement, the Executive Skeleton Tourbillon showcases the aesthetic codes of the Executive collection, making way for the essential.
The round titanium case, water-resistant to 30 meters, is topped with a ceramic bezel that matches the crown in black. Dressed in a dark shade, its athletic case middle further enhances the sleek and translucent mechanics that power the watch.
In the middle of the ring, the signature features of the Executive collection –oversized Roman numerals and hour-markers and imposing sword-shaped hands – seem to be suspended in midair. With its deep black color, the raised rectangular bridge stresses the skeleton watch’s place in Ulysse Nardin’s eminently contemporary collection. The movement has been carefully hollowed out to highlight these identifying features while preserving the power of its instantly recognizable aesthetics.
The watch’s finely shaped silhouette is matched by the power and performance of its beating heart, vibrating at a frequency of 2.5 Hz. Its complex mechanics, revealed in all their glory by the transparent sapphire crystal and coated with PVD and ruthenium, sketch a series of lively lines. With its exceptional power reserve of 170 hours and tourbillon made from silicium, the manually wound UN-171 Manufacture movement indicating the hours and minutes is tuned for endurance and accuracy. Sophisticated yet technical, a variety of finishes and colors enhance the refined architecture of this Ulysse Nardin Manufacture caliber.
A carbon fiber-style strap connects the case by three distinctive claws and is fastened by a folding titanium clasp.
