Designer
In-house design studio
The reference was drawn by the manufacture's internal design office, where case, dial and movement architects work alongside the watchmakers rather than as an outside commission.
Historical significance
Ulysse Nardin Blast 39 mm Black 18k sits within Ulysse Nardin's Blast line, introduced in 1963. It carries the house codes established since 1846 — 18k yellow gold case, black lacquer dial and in-house automatic, superlative chronometer — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
- Early production dials show a slightly different minute track, and collectors pay a premium for them.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.

Brand history
Ulysse Nardin has spent more than 180 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Freak, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Ulysse Nardin established Ulysse Nardin in 1846, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Ulysse Nardin calibre produced today.
