Swiss Fortis Flieger F-43 Bicompax Black F4240007 watches catch the eye at first glance with a typical pilot design with the clear signature of the Fortis brand. They are characterised by perfect clarity, robustness and durability. These watches will serve well not only in an aircraft cockpit, but also for everyday wear.
The Fortis Flieger F-43 Bicompax Black F4240007 watches have a case made of recycled stainless steel, complemented by a leather strap. Inside the case, the Swiss mechanical Fortis UW-51 movement (based on the Sellita SW510) works reliably with automatic winding. It runs at a frequency of 28800 vibrations per hour and has 27 jewels. The movement also has a hacking function (stopping the seconds hand when setting) and the option of manual winding via the crown. A chronograph function is available with a 30-minute counter at the 3 o'clock position. At the 6 o'clock position we find a practical date display. The bi-directional rotating GMT bezel allows reading the time in a second time zone.
The perfectly clear dial is protected by a sapphire crystal, which is highly resistant to scratches. The double-sided anti-reflective coating ensures excellent legibility even in direct sunlight. Legibility in the dark and in poor light conditions is enabled by SuperLuminova luminescence, placed on the hands and indices. The Synchroline® function is also available at the 12 o'clock position, which makes it easier for pilots to synchronise time with their colleagues within ±5 seconds. The water resistance of this model is 200 m, so it can handle greater contact with water, such as swimming or diving to approx. 20 metres. Water resistance is supported by a screw-down crown.
Personal import: For this model we offer the option of personal import (Prague and Central Bohemian Region) of the watch by the brand guarantor. If you are interested, please add a note to the order, 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.
