Swiss Fortis Flieger F-43 Triple-GMT Titanium Orange COSC F4260003 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 legibility, robustness and durability. These watches will serve well not only in an aircraft cockpit, but also for everyday wear.
The Fortis Flieger F-43 Triple-GMT Titanium Orange COSC F4260003 watches have a case made of titanium, complemented by a leather strap. Inside the case, the Swiss mechanical Fortis WERK 13 Manufacture movement (made for Fortis by Kenissi) with automatic winding operates reliably. It runs at a frequency of 28800 vibrations per hour, has 28 jewels and, above all, an extended power reserve of 70 hours. The movement also has a hacking function (stopping the seconds hand when setting) and the option of manual winding via the crown. Travellers in particular will appreciate the GMT function - i.e. a second time zone display in the form of a fourth hand. In addition, this is a so-called True GMT, where the GMT hand also moves when setting the time and the setting of the main hour hand then takes place in one-hour jumps, while the home time on the GMT hand remains unchanged. The bi-directional rotating GMT bezel allows the time to be read in an additional time zone. At the 3 o'clock position, there is a practical date display.
The movement has COSC certification. Thanks to this, it can bear the designation "Chronometer" and meets the strictest requirements for accuracy. Also worth mentioning is the special balance bridge with two-point fixation, thanks to which the watch is more resistant to shocks and thus minimises the chance of movement damage even during intense activity.
The perfectly legible 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. Under UV light, the Synchroline® function at the 12 o'clock position is visible, 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 delivery: For this model, we offer the option of personal delivery (Prague and Central Bohemian Region) of the watch by the brand guarantor. If you are interested, please add a note to the 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.
