Diver
History of the line
The Diver line has its roots in a dive watch produced by Ulysse Nardin in 1964, which for decades remained a marginal, little-known chapter of the brand's history compared with its more celebrated tradition of marine chronometers. The original model stood out for its large luminous indices, thick "pencil" hands and a knurled unidirectional bezel, typical features of 1960s diving instruments.
In 2017 the manufacture decided to bring this almost forgotten watch back to life with the Diver Le Locle, a reinterpretation faithful to the vintage spirit of the original model but with entirely modern mechanics: a 42.2 mm highly polished steel case, a sailcloth strap and, above all, the in-house UN-320 calibre with silicon escapement, which makes the watch practically immune to magnetism and provides around 48 hours of power reserve. The name chosen for the relaunch, "Le Locle", refers directly to the town where the manufacture was founded in 1846.
Alongside this historical reinterpretation, the Diver name was gradually adopted to group the brand's more contemporary dive watches into a collection of their own — direct heirs of the earlier Maxi Marine Diver models produced within the Marine line — with versions also focused on sustainability, including straps made from recycled fishing nets and cases designed for higher water resistance than the 2017 relaunch model.

Timeline of the line
Unlike almost all the manufacture's other lines, which have openly claimed their historical heritage since launch, the Diver Le Locle was born as a deliberate recovery of a model that for decades had remained on the margins of the brand's official story, brought back to light only with the 2017 relaunch.
