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. Billionaire 41 mm Silvered 18k sits within Jacob & Co.'s Billionaire line, introduced in 2022. It carries the house codes established since 1986 — 18k rose gold case, silvered opaline 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 case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
• The movement's bridges are decorated even where they will never be seen once the watch is cased.
• The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
