Male watches Fortis Stratoliner S-41 Gravity Black F2340018

The Swiss Fortis Stratoliner S-41 Gravity Black F2340018 watch bears the distinctive space-inspired signature of Fortis. It offers excellent legibility, robustness and durability. This model features a manufacture movement developed specifically for space travel and tested in the stratosphere. The watch can be used not only for space travel, but also for everyday wear.

The Fortis Stratoliner S-41 Gravity Black F2340018 has a case made of recycled stainless steel with a black DLC treatment, complemented by a rubber and nylon strap. The DLC treatment provides increased protection against scratches. Inside the case is the Swiss mechanical manufacture Fortis WERK 17 movement (made for Fortis in collaboration with La Joux-Perret), with automatic winding. It runs at a frequency of 28,800 vibrations per hour, has 26 jewels and an extended power reserve of 60 hours. The chronograph function has a minute counter at 12 o'clock and an hour counter at 6 o'clock. The movement also has a hacking function, which stops the seconds hand when setting the time, and can be wound manually using the crown. The movement can be viewed through the transparent sapphire crystal case back. A practical date and day-of-the-week display is located at 3 o'clock.

The highly legible dial is protected by a sapphire crystal, which is highly resistant to scratches. An anti-reflective coating on both sides ensures excellent legibility even in direct sunlight. SuperLuminova luminescence on the hands provides legibility in the dark and in poor lighting conditions. This model has a water resistance of 200 m, making it suitable for greater contact with water, such as swimming or diving to approximately 20 metres. Water resistance is supported by a screw-down crown.

The Fortis WERK 17 movement was developed and manufactured in collaboration with La Joux-Perret and is the first movement designed and intended specifically for use in space. So far, the movement has been tested in the stratosphere in collaboration with the Swedish space agency Swedish Space Corporation. Thirteen bare, unprotected watches were attached to a gondola mount. The gondola was carried into the stratosphere by a helium-filled balloon. Data was then recorded on a device beneath it. The ultimate goal was not simply for the watches to survive in the stratosphere. Among other requirements, their timekeeping accuracy had to remain unaffected. This is only the beginning of the Fortis WERK 17 movement's space mission. In collaboration with the Swedish space agency Swedish Space Corporation, the movement is to be sent 30 km into space to determine whether it can withstand harsh conditions such as microgravity, extreme temperatures and radiation.
