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 40 mm Silvered Stainless sits within Panerai's Submersible line, introduced in 1998. It carries the house codes established since 1860 — stainless steel case, silvered opaline dial and in-house automatic, superlative chronometer — 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 reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.

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.
