Formex Essence FortyOne Automatic Chronometer Space Ghost 0334.1.6643.100 Swiss watch immediately catches the eye with its dial made from Muonionalusta meteoriteand the newly introduced COSC-certified Sellita SW200-2 Power+ movement with an extended power reserve of 65 hours. The Formex Essence FortyOne is a modern take on a versatile watch suitable for any occasion, characterized by simple lines and excellent readability. Thanks to their overall set of features Formex Essence models are very popular among watch enthusiasts.
The Formex Essence FortyOne Space Ghost returns for 2026 in another limited edition of 150 pieces. This model builds on the exceptionally successful first edition, which sold out within a few dozen hours, and introduces significant technical improvements. It is, in fact, the first Formex model equipped with the all-new Sellita SW200-2 Power+ movement, which takes the already outstanding qualities of the Essence collection to an even higher level.
The Formex Essence FortyOne Space Ghost expandsthe range of special editions distinguished by their unique dials. In this case,the dial ismade from Muonionalusta meteorite —more than 4.5 billion years old—and iselectroplated with rhodium.
For the Space Ghost models, Formex also utilized an innovative electroplating process for the dial surface, taking advantage of the meteorite’s high iron content. The result is an accentuation of the Widmanstätten pattern, a structure characteristic of the Muonionalusta meteorite. Each texture is unique, making every dial an original and one-of-a-kind work of art.
The steel case of the Formex Essence FortyOne Automatic Chronometer Space Ghost, featuring a titanium inner container, has a brushed finish complemented by striking polished panels. The case is equipped with an innovative integrated Case Suspension System, which helps protect the movement from shocks. It now features a screw-down crown for even greater reliability during sports activities. Despite this technological enhancement, the case is only 10.6 mm thick.
The case is complemented by a steel bracelet featuring a redesigned butterfly clasp that can be extended by 3 or 6 mm without having to remove the watch from your wrist.
The watch is powered by the new Sellita SW200-2 Power+ ( Chronometer Grade) self-winding mechanical movement, which is COSC-certified. Compared to the previous generation, it features a redesigned construction that has increased the power reserve from 41 to65 hours without reducing the frequency. The movement thus continues to operate at a frequency of 28,800 half-vibrations per hour (4 Hz), which contributes to high accuracy and stability.
Of course, the movement includes crown winding, ahacking function to stop the seconds hand when setting the time, and a date window at the 6 o’clock position.
Classic features of the Formex Essence FortyOne Automatic Chronometer Space Ghost include a striking silver meteorite dial, 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 view the newly decorated movement with brushed bridges and blued screws.
Better readability in low-light conditions is ensured by luminescent material (BGW9 Super-LumiNova) applied to the handsand hour markers. The silver meteorite dial and high-gloss hour markers combine to create a very interesting effect. The overall impression is enhanced by the thoughtfully designed date window at the 6 o’clock position. You’ll especially appreciate the watch’s versatility—it’s designed for sports, water activities, and everyday wear.
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.
You can purchase a leather or rubber strap for the watch, featuringa carbon folding clasp with an innovative system for fine micro-adjustment within a 7 mm range. You can easily adjust the length by pressing the side button without having to remove the watch from your wrist.

New screw-down crown, designed for a case with a shock-absorption system.
New bracelet screws with precisely positioned threads—no need for anti-loosening adhesive.

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.
