The Swiss Fortis Novonaut N-42 Amadee-24 Limited Edition F2040016 watch bears the distinctive space-inspired signature of Fortis. It offers excellent legibility, robustness and durability. This watch can be used not only for space travel but also for everyday wear. The first successor to the iconic B-42 Official Cosmonauts was introduced in October 2023. The return of a legend was scheduled for none other than Friday the 13th. This version was developed in 2024 for use in the AMADEE 24 project, a simulation of astronauts staying on Mars, which took place in Armenia's Ararat province. This model is available in a limited edition of just 100 pieces worldwide. Of these, 20 are reserved for participants in the Amadee-24 expedition, leaving just 80 pieces available to the general public.
The Fortis Novonaut N-42 Amadee-24 Limited Edition F2040016 watch has a titanium case complemented by a bracelet made from the same material. A sliding mechanism on the clasp allows fine adjustment of the bracelet length without tools. The package also includes a special black elastic nylon strap. Inside the case is the reliable Swiss manufacture mechanical Fortis WERK 17 movement (made for Fortis in collaboration with the La Joux-Perret manufacture) with automatic winding. It runs at a frequency of 28800 vibrations per hour, has 28 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 (stopping the seconds hand when setting the time) and can be wound manually using the crown. A practical date and day-of-the-week display is located at 3 o'clock. The bidirectional rotating ceramic bezel can be used to measure intervals and is designed for counting down time. It also features the MCB™ system (Mission Control Bezel): two additional arrows with luminous dots on the bezel, spaced 10 minutes apart. The communication delay between Mars and Earth is 10 minutes, so astronauts can simply turn the bezel to track how long it will be until the next communication from ground control.
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, indices and bezel provides legibility in the dark and in poor lighting conditions. This model has a water resistance of 200 m, so it can withstand greater contact with water, such as swimming or diving to approximately 20 metres. Water resistance is supported by a screw-down crown with a triple seal. Various versions of this model's predecessor have been used many times on space flights by cosmonauts from the Roskosmos agency.
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. In collaboration with the Swedish space agency Swedish Space Corporation, the movement was tested in the stratosphere, with thirteen bare, unprotected watches 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, this movement was sent 30 km into space, where it was verified that it could withstand harsh conditions such as microgravity, extreme temperatures and radiation.
This special edition was developed for use in the AMADEE 24 crewed Mars mission simulation. It took place in 2024 in Armenia's Ararat province and involved 6 specially trained OeWF analogue astronauts. The test site in Ararat province was selected for its geological and topographical similarity to Mars. During the mission, the astronauts were in complete isolation in a habitat in the Armenian desert. A dedicated mission support centre in Austria is responsible for communication with the outside world, with a ten-minute communication delay to be simulated. The Amadee-24 programme was carried out by the Armenia Aerospace Agency. It is a project of the Austrian institution Austrian Space Forum, the only organisation in Europe and one of four worldwide that develops spacesuit technology for human missions to Mars. The aim is to simulate surface activities on Mars.
Note: although the case measures 42 mm, the bezel extends 1 mm beyond the case, giving the watch the appearance of a 44 mm size.
Personal delivery: For this model, we offer personal delivery of the watch by the brand representative in Prague and the Central Bohemian Region. If you are interested, please add a note to your order and we will contact you. More information here.

The Swiss brand Fortis fully fulfills the meaning of its name, which means "strong" in Latin. It is synonymous with durability, robustness and reliability. Its purely mechanical watches serve professional pilots well, can be used underwater and have even served cosmonauts in space! In the years 1994-2019, Fortis watches were the official equipment of cosmonauts of the space agency Roskosmos. However, the foundations of Fortis' journey into space were already laid in 1961, when the founder's son Rolf Vogt showed the Fortis Spacematic AR (All Risks) watch to NASA astronauts. It was not until 1994 that the Official Cosmonauts Chronograph model looked into open space as part of the preparatory work for the historic connection of the American space shuttle Atlantis with the Russian MIR station.
Fortis is currently working with the Austrian Space Forum as the official timekeeper for the AMADEE Mars Mission simulation. From 2021, the Swedish Space Corporation became the official partner of Fortis in the testing and development of a purely space watch Fortis, where the stratospheric tests of the Werk 17 movement will be of particular interest.
The Fortis brand was founded in Grenchen, Switzerland in 1912 by Mr. Walter Vogt and, in addition to the already mentioned space successes, it has also achieved many other interesting milestones. In 1926, Fortis, in collaboration with the inventor of the first automatic movement, John Harwood, recorded the world's first serial production of a self-winding mechanical watch! Fortis introduced one of the world's first waterproof watches in 1940. Since 2018, its lifelong fan Jupp Philipp has become the owner of the Fortis brand.
Helveti.cz is an authorized dealer and specialist of the Fortis brand.
