Ulysse Nardin once again pushes the boundaries of watchmaking by unveiling the all-new DIVER [AIR] dive watch, setting a record-breaking weight of just 52 grams, making it the lightest mechanical dive watch in the history of watchmaking. This timepiece seamlessly integrates haute horology aesthetics, ultra-lightweight design, and rigorous diving standards, reshaping traditional perceptions of sporty tool watches. Since the debut of dive watches in the 1950s, the market has seen countless water-resistant and robust designs, yet Ulysse Nardin firmly believes that limits are not the end but a new beginning, redefining high-performance timepieces through technological innovation and creativity.
The DIVER [AIR] features the UN-374 skeleton automatic movement, a masterpiece born from further lightweight engineering and structural reorganization of the brand’s UN-372 released in 2021. Weighing in at just 7 grams, the movement’s design reimagines the bridges and barrel structure, significantly reducing material usage while maintaining stability. An impressive 80% of its internal space is skeletonized, with the bridges formed using a triangular structure that blends aesthetics with shock resistance. It has been tested to withstand impacts of up to 5,000g. Even under rigorous use, it maintains a 90-hour power reserve and exceptional precision, showcasing its remarkable technical prowess.
The brand stays true to the core standards of dive watches, including automatic winding, 200-meter water resistance, and practical functionality. The DIVER [AIR] movement features a large silicon balance wheel and a recycled silicon escapement component, embodying a watchmaking philosophy that values both sustainability and precision. Comprising 199 components in total, it operates at a frequency of 21,600 vibrations per hour, flawlessly combining form and function.
More than just its movement, this 44mm timepiece breaks new ground with its innovative case design. The central structure is crafted from 90% recycled titanium, a result of collaboration with TiFast and Thyssenkrupp. For the first time, the sides incorporate Nylo®-Foil nylon fiber, a unique fusion of discarded ocean fishing nets and recycled carbon fiber. This material boasts a distinctive marbled texture while being lighter than traditional carbon fiber. The luminous unidirectional rotating bezel is made from 100% recycled CarbonFoil, melding mechanical aesthetics with practical phosphorescent functionality to meet the demands of deep-sea diving.
When it comes to the finer details, Ulysse Nardin remains focused on delivering an exceptional user experience. The DIVER [AIR] comes equipped with two elastic fabric straps in vibrant orange and clean white, both crafted from lightweight materials and featuring a tool-free quick-release design. This ensures a comfortable fit and easy strap swaps. The total weight of the watch, including the strap, is just 52 grams, and a mere 46 grams without the strap. It’s effortlessly light for everyday wear, making it a true masterpiece that perfectly balances mechanical artistry with practical functionality.
And all these achievements stem not only from the creativity of a single department but also from nearly two decades of the brand’s dedication to high-tech material research. From pioneering the sans-dial and sans-crown concept with the Freak series in 2001 to introducing silicon escapement systems, Ulysse Nardin has consistently challenged traditional boundaries. By combining sustainable recycled materials with cutting-edge craftsmanship, they are shaping the future of sustainable haute horology. The DIVER [AIR] perfectly embodies this spirit—not only setting a new standard for lightweight design in the market but also redefining the concept of traditional dive watches.
