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

Hublot Classic Fusion 43 mm Green Sapphire sits within Hublot's Classic Fusion line, introduced in 1980. It carries the house codes established since 1980 — sapphire crystal case case, green sunburst dial and in-house automatic chronograph — 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.
  • 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.
