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

Jacob & Co. Casino Tourbillon 38 mm Green Carbon sits within Jacob & Co.'s Casino Tourbillon line, introduced in 1986. It carries the house codes established since 1986 — carbon tpt case, green sunburst dial and in-house automatic micro-rotor — 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

Jacob & Co. has spent more than 40 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Astronomia, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.

Jacob Arabo established Jacob & Co. in 1986, working from United States at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Jacob & Co. calibre produced today.
