Designer

Emmanuel Gueit

Emmanuel Gueit came from a family of Geneva jewellers and was barely into his twenties when he drew the oversized Royal Oak Offshore in 1993 — a watch the house's traditionalists resisted and collectors turned into an icon.

Historical significance

Hublot Square Bang 38 mm Black 18k sits within Hublot's Square Bang line, introduced in 1980. It carries the house codes established since 1980 — 18k rose gold case, black lacquer dial and in-house automatic chronograph — 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 movement's bridges are decorated even where they will never be seen once the watch is cased.

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.
