Historical significance

Jacob & Co. Billionaire 40 mm Salmon Stainless sits within Jacob & Co.'s Billionaire line, introduced in 2019. It carries the house codes established since 1986 — stainless steel case, salmon dial and in-house manual-winding, hand-finished — 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.
• Early production dials show a slightly different minute track, and collectors pay a premium for them.
