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 MP Collection 38 mm Slate 18k sits within Hublot's MP Collection line, introduced in 1980. It carries the house codes established since 1980 — 18k yellow gold case, slate grey dial and in-house automatic, chronometer certified — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- Early production dials show a slightly different minute track, and collectors pay a premium for them.
- 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.
