The Formex Stratos UTC Automatic 41mm Green is a modern interpretation of a pilot’s watch by the Swiss brand Formex. Its distinctive, instantly recognisable case and highly legible dial stand out at first glance. The watch is particularly versatile: its features make it suitable for travel, sport, use in water and as a reliable everyday accessory. Thanks to the GMT function, you can keep track of up to three time zones at once.
The Formex Stratos UTC features a highly intuitive and practical true GMT function. The watch is powered by an ETA 2892 movement with a Dubois-Dépraz module specially modified by Formex, making time zone adjustment straightforward. Simply press one of the buttons on the side of the case to move the hour hand displaying local time forwards or backwards by one hour, while the GMT hand remains in place. The date, displayed in a subdial at 6 o’clock, responds to the movement of the hour hand and can be adjusted forwards or backwards with it. A correction button on the left side of the case also allows the date to be set quickly. There is therefore no need to operate the screw-down crown to change the date. The final function is a local time day/night indicator at 9 o’clock, which is useful when setting the watch.
The multi-layered case of the Formex Stratos UTC Automatic is made of steel, with brushed surfaces alternating with sandblasted recesses, complemented by hand-polished lines. The case is topped by a bidirectional 48-click bezel with a resin insert and 24-hour markings. Despite its robust appearance, the case is only 12 mm high.
The case is supplied with a leather strap fitted with a folding clasp featuring an innovative fine micro-adjustment system with a range of up to 7 mm. It can alternatively be replaced with a steel link bracelet from the Essence collection, fitted with a folding clasp with micro-adjustment and a length adjustment range of up to 5 mm. Both straps and bracelets feature a quick-release system, making them easy to change without tools.
The watch is powered by an ETA 2892 automatic mechanical movement with a Duboiz-Dépraz module and a power reserve of approximately 42 hours. The movement operates at 28,800 vibrations per hour and can be wound using the crown. It also features a stop-seconds function when setting the time (hacking). In addition to the date, the watch offers a GMT function (display of a second time zone), allowing up to three time zones to be displayed using the 24-hour hand, fixed 24-hour scale and rotating bezel. The local time hand (hour hand) can be moved in independent one-hour increments using the side buttons, independently of the current time (true GMT) and without pulling out the crown. The watch has a water resistance of 100 m (10 ATM), supported by a screw-down crown and case back, making it suitable for water activities. The case diameter is 41 mm, making the watch suitable for most men’s wrists.
The characteristic features of the Formex Stratos UTC Automatic include a distinctive, legible dial, increased water resistance and a clasp with fine micro-adjustment. The clear dial is protected by a highly scratch-resistant sapphire crystal with an internal anti-reflective coating. Sapphire is also used for the case back, through which the decorated movement with blued screws can be viewed. Luminescence (BGW9 Super-LumiNova) on the hands and indices improves legibility in low light.
As is customary for Formex, the dial is precisely finished to a high standard. It features a brushed centre with a sunburst effect, surrounded by a ring with a coarser texture and an original numeral font. The GMT hand provides sufficient contrast for clear legibility. The overall appearance is complemented by a carefully designed day/night indicator at 9 o’clock and date at 6 o’clock. The watch is particularly versatile: its features make it suitable for sport, use in water, travel and as an everyday accessory.
The watch can be supplied with a steel bracelet fitted with a butterfly clasp that can be extended by 4 mm, or a leather strap fitted with a carbon folding clasp featuring an innovative fine micro-adjustment system with a range of 7 mm. Its length can be easily adjusted by pressing the side button without removing the watch from your wrist.
A premium wooden box can also be selected instead of the standard box for an additional charge.
The watch can also be found under the reference Formex 1101.1.6401.xxx

Formex Watches is an independent Swiss watch manufacturer based in Biel-Bienne, the cradle of Swiss watchmaking, where the entire production process takes place from design, development, assembly and testing of all watches. The company was founded in 1999 with the aim of producing watches that will meet the highest quality standards. The brand is known for the use of high-tech materials and the development of unique improvements and functions, leading to the technical perfection of the watch and an increase in wearing comfort - for all of them, let's name the Case Suspension System, a patented suspension system of the case, protecting the movement of the watch during impacts and increasing comfort on the wrist.
The Formex brand was founded by two brothers, watchmakers and watch enthusiasts who wanted to combine their passion for watches with their love of motorsport. High resistance is therefore typical for the design of the watch, suitable even for extreme conditions. It is aimed not only at watch lovers, but also at all athletes, outdoor enthusiasts and adventurers who require functionality and high reliability.
Formex is a combination of the French words "forme" and "extrème", loosely translated as extreme form/shape. All watches assembled at the brand's headquarters in Biel-Bienne meet the strictest requirements of the Swiss Made label. Every single piece goes through careful quality control and testing. Formex watches reflect love for watchmaking, high quality workmanship, innovative approach, relentless development, use of special materials and exceptional craftsmanship.
Helveti.eu is an authorized retailer, specialist and certified expert of the Formex brand.
