About the Diver family
The Diver collection is Ulysse Nardin's line of dive watches, with rotating bezels, strong luminous markings and robust cases. Recent models include sizes from smaller three-hand watches to larger chronographs and the sporty Diver X, and some use recycled steel and other recycled materials.
The references in this catalog are in steel, recycled steel, titanium and black-coated titanium, with calibers such as the in-house UN-118 and the UN-816. Check the bezel action, the strap or bracelet, and the dial colour against the reference.
