This model actually has a smooth leather strap without a pattern, but a product image with the correct strap is not available.
The Swiss watch Fortis Pilot Classic Chronograph 904-21-41-L catches the eye at first glance with a typical pilot design with the clear signature of the Fortis brand. It is characterised above all by perfect legibility. This watch will serve well not only in an aircraft cockpit, but also for everyday wear.
The Fortis Pilot Classic Chronograph 904-21-41-L watch has a case made of stainless steel, complemented by a leather strap. Inside the case, the Swiss mechanical movement ETA 2892-A2 with the Dubois Depraz 2020 module (which provides the chronograph function) operates reliably. It runs at a frequency of 28800 vibrations per hour, and also has a hacking function (stopping the seconds hand when setting) and the option of manual winding via the crown. You can use the chronograph function with a minute counter at the 12 o'clock position and an hour counter at the 6 o'clock position. The movement can be observed through the transparent case back.
The perfectly legible dial is protected by a sapphire crystal, which is highly resistant to scratches. The anti-reflective coating ensures excellent readability even in direct sunlight. Readability in the dark and in reduced light conditions is enabled by SuperLuminova luminescence, applied to the hands and indices. The water resistance of this model is 50 m, so it can handle minor contact with water, such as rain or a shower.

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.
