Introducing a mechanical diver's watch weighing just 52g from Ulysse Nardin!
At Watches & Wonders Geneva, Ulysse Nardin unveiled its new 2025 watch: the Diver Air.
Automatic (Cal. UN-374). 21 jewels. 21,600 vph. Power reserve approximately 90 hours. Titanium and carbon fiber (diameter 44mm, thickness 14.7mm). Water resistant to 200m. Price: 6,435,000 yen (tax included).
The latest addition to the Ulysse Nardin "Diver" collection is the world's lightest mechanical diver's watch. Its weight, including the head and strap, is just under 52g, less than half the weight of a typical diver's watch. The head itself weighs less than 46g, and the strap less than 6g. To achieve the ultimate in lightness, both the exterior and the movement have been thoroughly redesigned.
The 44mm case is crafted from two materials: titanium, a material also used in motorsport and aerospace, and carbon fiber. The caseband is made from 90% recycled titanium, while the side sections are made from a composite material made from 60% recycled fishing net Nylo® and 40% upcycled carbon fiber. The bezel is made from 100% upcycled carbon fiber.
The movement is the Caliber UN-374, based on the Caliber UN-372 used in the Diver X Skeleton. 90% recycled titanium is used for the bridges and main plate, and each part has been shaved down to reduce weight. Surprisingly, it maintains the robustness required for a diver's watch, having passed a 5000G shock resistance test. Performance is uncompromising, boasting a power reserve of approximately 90 hours.
The selling price is 6,006,000 yen (tax included).
