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
Hublot Big Bang 43 mm Salmon Stainless sits within Hublot's Big Bang line, introduced in 1982. It carries the house codes established since 1980 — stainless steel case, salmon dial and in-house automatic, chronometer certified — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.

Brand history
Hublot has spent more than 46 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Big Bang, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Carlo Crocco established Hublot in 1980, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Hublot calibre produced today.
