Historical significance

Fortis Novonaut 44 mm Slate Sapphire sits within Fortis's Novonaut line, introduced in 2012. It carries the house codes established since 1912 — sapphire crystal case case, slate grey dial and automatic powermatic 80 — 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.
  • Early production dials show a slightly different minute track, and collectors pay a premium for them.

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.
