Designer
In-house design studio
The reference was drawn by the manufacture's internal design office, where case, dial and movement architects work alongside the watchmakers rather than as an outside commission.
Historical significance
Fortis Stratoliner 41 mm Ice 18k sits within Fortis's Stratoliner line, introduced in 1993. It carries the house codes established since 1912 — 18k white gold case, ice blue dial and automatic cosc chronometer — 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.
