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
Fortis Marinemaster 42 mm Slate Ceramic sits within Fortis's Marinemaster line, introduced in 2023. It carries the house codes established since 1912 — ceramic case, slate grey dial and automatic, 38-hour reserve — 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 bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.

Brand history
Fortis has spent more than 114 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Flieger, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Walter Vogt established Fortis in 1912, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Fortis calibre produced today.
