Fortis Stratoliner S-41 Gravity Black Ref. F2340018. Swiss chronometer-certified space chronograph powered by the Manufacture Werk 17 calibre. Column wheel architecture, 60-hour power reserve and engineering developed for the demanding conditions of the stratosphere.

The Fortis Stratoliner S-41 Gravity Black was not designed to celebrate the past. It was built for the future.

Powered by the chronometer-certified Manufacture Werk 17, this column wheel chronograph combines exceptional precision with the robustness expected from a professional instrument. Developed for stratospheric testing missions, it represents a modern vision of Swiss watchmaking where performance always comes first.

Its compact 41 mm case, stealthy black finish and highly legible dial create a chronograph that feels purposeful rather than decorative. And when darkness falls, the Super-LumiNova® X1 display transforms the watch into a striking instrument panel, delivering remarkable visibility and reinforcing its unmistakable space-inspired character.

Precise, technical and refreshingly different, the Stratoliner is a chronograph for enthusiasts who appreciate engineering, innovation and authentic mechanical substance.
