The Swiss Fortis Stratoliner S-41 Cosmic Gray F2340008 watches are a testament to the specific cosmic handwriting of the Fortis brand. Of course, it is perfect in terms of clarity, robustness and durability. This model features a manufactory movement, developed specifically for space travel and tested in the stratosphere. However, this watch can be used not only for space travel, but also for everyday wear.

The Fortis Stratoliner S-41 Cosmic Gray F2340008 has a case made of recycled stainless steel, complete with a steel tension. Fine adjustment of the bracelet length is made possible by a sliding mechanism on the clasp. The Manufacture Swiss mechanical movement Fortis WERK 17 (made for Fortis in cooperation with the Manufacture La Joux-Perret) with automatic winding works reliably in the case. It runs at a frequency of 28,800 semi-frequencies per hour, has 26 jewels and an extended power reserve of 60 hours. The stopwatch function can be used with a minute counter at 12 o'clock and an hour counter at 6 o'clock. The movement also has a "hacking" function (stopping the second hand when ordered) and the possibility of manual winding by the crown. The movement can be observed through a transparent sapphire crystal. At the 3 o'clock position we find a practical date and day of the week display.

The perfectly clear dial is protected by a sapphire crystal that is extremely scratch-resistant. The double-sided anti-reflective coating ensures excellent legibility even in direct sunlight. The SuperLuminova luminescence, located on the hands, enables legibility in darkness and low-light conditions. The water resistance of this model is 200m, so it can handle even greater contact with water, such as swimming or diving to about 20 meters. The water resistance is supported by a screw-down crown.

TheFortis WERK 17 has been developed and manufactured in collaboration with La Joux-Perret and is the first movement to be designed and manufactured specifically for use in space. The movement has so far been tested in the stratosphere in collaboration with the Swedish Space Corporation, where thirteen bare, unprotected watches were attached to a nacelle mount. It was carried into the stratosphere by a balloon powered by helium gas. The data was then recorded on the device below. Of course, the watch's survival in the stratosphere was not the ultimate goal. It was also a prerequisite, among other things, that the precision of the operation be undisturbed. But this is only the beginning of the Fortis WERK 17's space mission. In cooperation with the Swedish Space Corporation, the movement is to be sent 30km into space to see if it can withstand harsh conditions such as microgravity, extreme temperatures and radiation.
