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
Panerai Submersible 42 mm Blue Ceramic sits within Panerai's Submersible line, introduced in 1951. It carries the house codes established since 1860 — ceramic case, blue "grande tapisserie" 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 movement's bridges are decorated even where they will never be seen once the watch is cased.

Brand history
Panerai has spent more than 166 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Luminor, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Giovanni Panerai established Panerai in 1860, working from Italy at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Panerai calibre produced today.
