Always innovating, Ulysse Nardin, introduces the new Diver [AIR]; a skeletonized, high horology sport watch designed for extremes. The Diver [AIR] is the world's lightest mechanical dive watch. To achieve the Diver [AIR]’s exceptionally light weight of just 52g including the strap, and under 46g without it, material had to be removed from the Diver X Skeleton’s calibre UN-372 while ensuring the watch’s reliability and performance remained uncompromised. Thus, the calibre UN-374 was born. Despite the space inside the case being 80% air and just 20% watch movement, the highly skeletonized calibre UN-374 can withstand an impact of an impressive 5,000g. It has been rigorously tested, cycling thousands of shocks over several days not just in the lab, but in real-world use too, putting the watch through its paces to prove it can be worthy of the Ulysse Nardin name. Comes with both an orange and a white elastic fabric strap.
