The Swiss Fortis Marinemaster M-44 Black Resin COSC F8120018 watch brings an unusual diver's design in the style of the Fortis brand. It is decorated with perfect clarity, robustness and durability. This watch will serve you well not only underwater, but also in everyday wear.
The Fortis Marinemaster M-44 Black Resin COSC F8120018 has a case made of recycled stainless steel, complete with a steel tension. Fine adjustment of the bracelet length is made possible by a sliding mechanism on the clasp. The Swiss mechanical manufacture movement Fortis WERK 11 (manufactured for Fortis by Kenissi) with automatic winding works reliably in the case. It runs at a frequency of 28,800 semi-frequencies per hour and features 26 jewels and, above all, an extended power reserve of 70 hours. The machine also has a "hacking" function (stopping the second hand when ordered) and the possibility of manual crown winding. At the 3 o'clock position we find a practical date display. The bi-directionally rotatable diving lunette with the possibility of locking by the "Fortis Lock System®" (at the 10 o'clock position) allows the measurement of time periods.
The machine is COSC certified. Thanks to this, it can carry the "Chronometer" designation and meets the most stringent requirements for precision operation. It is also worth mentioning the special flywheel bridge with two-point fixation, which makes the watch more resistant to shocks and minimizes the chances of damaging the movement even during intense activity.
The perfectly clear structured dial is protected by a sapphire crystal, which is maximally scratch-resistant. The double-sided anti-reflective coating ensures excellent legibility even in direct sunlight. The SuperLuminova luminescence on the hands and indexes enables readability in darkness and low-light conditions. The water resistance of this model is 500m, so it can handle even greater contact with water, such as diving. The water resistance is supported by a screw-down crown with a triple seal system.

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.
