The Ulysse Nardin Automatic 300M watch belongs to the new Diver Chronometer line of the Kering brand. This high-end diving watch with a titanium case draws its particularity from its unidirectional rotating bezel as well as its surface treatments, chromatic choices, and readability. Its UN-118 caliber motor gives it an operating reserve of 60 hours. The watch benefits from silicon technology, which ensures its balance spring and escapement an optimized resistance to magnetic fields, temperature changes, and shocks, and thus perfectly adapts it to its sporting vocation.
