Designer
Jörg Hysek
Jörg Hysek left Rolex and Seiko's European studios to build a design practice in Geneva, giving houses such as Vacheron Constantin, Breguet, Seiko and TAG Heuer their sculptural, architecture-led cases before founding his own brand, HD3.
Historical significance
Jacob & Co. Twin Turbo Furious 39 mm Slate Platinum sits within Jacob & Co.'s Twin Turbo Furious line, introduced in 1986. It carries the house codes established since 1986 — platinum 950 case, slate grey dial and in-house tourbillon, manual-winding — 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 case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

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.
