Formex Essence Leggera FortyOne Automatic Chronometer Forged Carbon Black Rubber 0331 Swiss watch .4.6399.910 immediately catches the eye with its black case featuring a ceramic bezel with a striking brushed finish and a unique carbon fiber dial with an original pattern on each individual piece. They are the ideal choice for all watch enthusiasts who also lead an active lifestyle, offering a modern take on a versatile watch suitable for any occasion, characterized by simple lines and excellent readability.
The case of the Formex Essence Leggera 41 Forged Carbon watch is a combination of carbon and ceramic. The base of the case is made entirely of carbon and is complemented by a black ceramic bezel with striking reflections. This combination creates a highly durable watch that shows no visible scratches, even after prolonged use.
The case is equipped with an innovative integrated Case Suspension System, which helps protect the movement from shocks and enhances wearing comfort by allowing the case to partially adapt to the wrist during movement. Despite this technological enhancement, the watch is only 11 mm thick. The case is complemented by a black rubber strap featuring a folding clasp with an innovative system for fine micro-adjustment within a range of up to 7 mm.
The watch is powered by a Sellita SW200-2 Power+ (Chronometer Grade) self-winding mechanical movement with COSC certification and a power reserve of approximately 65 hours. The movement, operating at a frequency of 28,800 half-vibrations per hour, features winding via the crown, a hacking function to stop the seconds hand when setting the time, and a date display at the 6 o’clock position.
The watch is water-resistant to 100 m (10 ATM). With a case diameter of 41 mm, the watch fits perfectly on most men’s wrists.
Classic features of the Formex Essence Leggera FortyOne Automatic Chronometer Forged Carbon include a carbon case with a ceramic bezel, the Case Suspension System, enhanced water resistance, and a buckle with fine micro-adjustment. The easy-to-read dial is protected by a sapphire crystal with an internal anti-reflective coating and high scratch resistance. Sapphire is also used for the case back, through which you can observe the movement of the decorated mechanism with blued screws. Better readability in low-light conditions is ensured by luminescent material (BGW9 Super-LumiNova) applied to the hands and hour markers. It is precisely the carbon-fiber dial and the high-gloss hour markers that create a very interesting effect. The overall impression is enhanced by the thoughtfully designed date window at the 6 o’clock position , featuring a ring in the same color as the dial. Interestingly, thanks to the manufacturing process, each dial is unique and features an original pattern. You’ll especially appreciate the watch’s versatility; its combination of features makes it ideal for sports, water activities, and everyday use.

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.
