Lightest in The First Half of 2025

Ulysse Nardin's achievements in the dive watch market are undoubtedly outstanding, and its breakthroughs in weight over the past six years are equally remarkable. From the 2019 Diver, which weighed 120.5 grams, to the 2021 Diver X Skeleton, which weighed 105.8 grams, and finally the 2025 Diver Air, the case weighed 35.6 grams, the movement 10.1 grams, and the strap 6 grams, the entire watch weighed less than 52 grams—an astonishingly impressive achievement.

Such a lightweight design is achieved through the use of high-tech materials and the extensive skeletonization of the dial to minimize unnecessary weight. The 44mm case features a 90% recycled titanium middle, Nylo®-Foil nylon on the sides, and CarbonFoil on the unidirectional rotating bezel.

The movement has been reduced to an extreme, with a skeletonization of up to 80%, leaving only 20% of the movement unreduced. The new flying barrel has its upper plywood removed and skeletonized. While ensuring lightweight, the movement features a sturdy triangular structure with enhanced shock resistance, capable of withstanding up to 5000 g-forces, ensuring a worry-free experience whether for serious diving or daily wear. The UN374 automatic movement, paired with an oversized silicon balance wheel and hairspring, vibrates at 21,600 vibrations per hour. Don't assume that such a light watch will compromise battery life; the power reserve is still a staggering 90 hours, longer than most watches on the market.
