Fortis Watches, a Swiss luxury watch manufacturer, has a rich and illustrious history that dates back to its founding in 1912. The company was established by Walter Vogt, who had a vision of creating timepieces that were not only aesthetically pleasing but also reliable and functional. In the early years, Fortis gained recognition for its innovative approach to watchmaking. It introduced the first automatic wristwatch in 1926 and became known for its precise timekeeping.

During World War II, Fortis supplied watches to pilots in various air forces, solidifying its reputation for producing durable and accurate timepieces. In the 1960s, Fortis made another significant breakthrough by launching the world's first space-tested watch. The Cosmonaut Chronograph was worn by astronauts during their missions and proved its reliability in extreme conditions. Over the years, Fortis has continued to innovate and create watches that cater to different needs.

Today, they offer a wide range of collections including aviation-inspired models and diving watches built for underwater exploration.

What’s On Offer 

The stylish yet functional Fortis Cosmonautis crafted from stainless steel and presents in a 39mm case which wears very nicely on the wrist with superb proportions comprising the crown guards and crown. The dial is perfectly black and is super legible due to the sapphire crystal being anti-reflective on both sides. Arabic numerals mark the hour plots with luminous pips and lume squares at 3, 6, and 9 and a lume triangle at 12. Chunky pencil hands are also luminous making the dial excellent in low light! The watch is powered by the ETA 2836-2 which is known for its high accuracy and reliability. It features 25 jewel bearings, enhancing its longevity and resistance to wear.

A nice robust tool watch with plenty of presence on the wrist - we love it!
