ABOUT THIS WATCH

The Essence Space Ghost 41 mm features a dial crafted from genuine Muonionalusta meteorite, a material that formed approximately 4.5 billion years ago. As the meteorite cooled over millions of years in space, its iron and nickel content crystallized into the Widmanstätten pattern visible on every dial today. Because this structure occurs naturally, no two dials are alike. A proprietary rhodium treatment developed by Formex and Swiss dial manufacturer Cadranor protects and enhances the meteorite's natural texture and silvery appearance, while blued hands and indexes provide clear contrast and legibility.


The watch is housed in the latest-generation Essence case, featuring a screw-down crown and a redesigned stainless-steel bracelet with Formex's integrated three-position on-the-fly micro-adjustment system. Without removing the watch from the wrist or opening the clasp, the bracelet length can be instantly adjusted between 0, 3, and 6 mm positions, allowing the fit to adapt throughout the day as wrist size changes. Both the bracelet and straps can be exchanged in seconds without the use of tools.


Powering the watch is Sellita's new SW200-2 Power+ automatic movement in its highest-quality Chronometer grade. Individually certified by the COSC, the Swiss Made caliber delivers a 65-hour power reserve and benefits from improved winding efficiency and enhanced shock resistance. Visible through the sapphire crystal caseback, the movement features brushed decoration, blued screws, and Formex's custom-developed skeletonized rotor.


The Essence Space Ghost 41 mm is produced in small annual batches, with the current production limited to 150 pieces.

FEATURES

An Automatic, also called self-winding watch, is a mechanical watch in which the mainspring is wound automatically as a result of the natural motion of the wearer's arm, to provide energy to run the watch, making manual winding unnecessary. All our Automatic movements are manufactured in Switzerland.

A chronometer is a watch that has been tested and certified to meet the most strict precision and accuracy standards. “Chronometer” isn’t just a name that any watch brand can print on the dial of its watches. It is an official nomenclature, defined by precise rules, which lay down the definition of the term “chronometer”, describing the categories, the test programme and the acceptable minimum requirements for wrist chronometers. In Switzerland, the COSC, or Contrôle Officiel Suisse des Chronomètres, is the only official organisation allowed to certify chronometers.

Modeled with high-performance bikes and racing cars in mind, Formex’s patented Case Suspension System works by integrating four springs between the upper and lower watch case. The result is the ultimate shock absorption system designed to protect the watch movement and deliver unparalleled comfort to the wearer.
This watch features an ultra-strong and light-weight folding clasp, made of carbon fiber composite and a stainless steel or titanium buckle. The gradual fine adjustment system allows you to tighten or loosen the strap length when the wrist size varies due to temperature and activity.
All straps and bracelets can be interchanged by hand without the use of any tools and in a few mere seconds. This allows you to easily swap straps on the go and wear your personal style for any occasion.
A sapphire crystal or “glass” is a very hard, transparent material made of crystallizing pure aluminium oxide at extremely high temperatures. Sapphire is one of the hardest substances on earth. It measures 9 on the Mohs scale (diamond measures 10, the highest rating), which is a system for rating the relative hardness of various materials, making it virtually scratch proof.
Applying AR coating will limit the reflection on a sapphire or mineral glass to a very low level.
The transparent case back, made of sapphire crystal, makes it possible to see the movement inside the watch.
Water resistance measures how much water pressure a watch can handle before it breaks. This measurement is important to know for the proper care and keeping of your watch. Water resistance of 100 m / 330 ft means that it can be used for swimming, snorkeling, and similar activities.

We back our watches with a 3-Year international warranty. In the rare case of a malfunction or a movement defect, you can contact us and send your watch back free of charge and we’ll repair it for you within 2 weeks.
Formex is dedicated to online payment security. We do not store any of your payment information. We offer payment solutions tailored to your shipping destination. Please proceed to checkout to view your local payment options.
All watch prices already include free shipping worldwide. As soon as we have processed your order, you will receive a tracking number to follow your package.

If you contact us before returning or exchanging your watch, we’ll even have your shipping expenses covered.
All our watches are designed, developed and assembled in-house at our headquarters in Biel-Bienne, Switzerland and meet the current, more strict Swiss Made requirement, which entered into force on January 2017. Every single piece undergoes a variety of quality and functionality controls, before making it to your wrist.

NEW 41 mm Stainless Steel Case

We aren’t just filling a gap between 39 and 43. We took the chance to ask: where can we make it better? The result is a real sweet-spot size that wears just right for a broader community – and upgrades across the board. The new butterfly clasp lets you micro-adjust the fit over a wider range, on the fly, without opening it, and it still looks completely seamless on the wrist. The redesigned screw-down crown works seamlessly with our Case Suspension System, locking in securely without compromising comfort. And then there’s the meteorite dial – silver-finished, deep-patterned, with blued hands and markers that give it real presence. That’s the Formex way: keep pushing, tweak the details, and make every watch a step forward.

officially certified movement

This watch is powered by the Swiss Made Sellita SW200-2 Power+ self-winding movement with a power reserve of 65 hours. Selected in its highest-quality grade, "Chronometer", the movement features premium components such as a Glucydur balance wheel, renowned for its exceptional hardness, dimensional stability, resistance to deformation, non-magnetic properties, and corrosion resistance. The movement is fully decorated and fitted with Formex's in-house developed and custom-built skeletonized rotor. Its finishing combines a contemporary brushed surface treatment with blued screws, reflecting the same attention to detail found throughout the watch. Each movement is individually certified by the COSC (Official Swiss Chronometer Testing Institute) and undergoes the rigorous 15-day testing protocol to verify exceptional levels of mechanical accuracy and precision. Every certified chronometer is uniquely identified by both an engraved movement number and a corresponding COSC certificate number. While fewer than 3% of Swiss watch movements receive official chronometer certification, Formex goes a step further by conducting additional rate testing after assembly according to the same criteria, ensuring that the performance achieved during certification is maintained once the movement is installed in the completed watch.

FINE ADJUSTMENT CLASP

Besides contributing to visual appeal, the details on the Essence FortyOne also serve a purpose. For a timepiece to be a watch for all occasions, it needs to feel exceptionally comfortable on the wrist. For even more wrist comfort, Formex added their patented Carbon Fiber Composite Folding Clasp that allows for fine-adjustment of the strap length on the go, allowing for a perfect fit on the wrist in all conditions and temperatures. The strap can be changed without the use of any tools with Formex's patented quick release system. The stainless steel bracelet with screwed links has the same quick release system and also features a unique micro-extension system.

A METEORITE ON THE WRIST

The Space Ghost debuts with a dial cut from the Muonionalusta meteorite – a fragment over 4.5 billion years old that struck Earth more than a million years ago after traveling through space at –270°C. Its distinctive Widmanstätten pattern, formed through slow cooling over eons, gives each dial its own intricate, interlacing structure – no two are alike.


To preserve the meteorite’s natural beauty and prevent oxidation, Formex, together with Cadranor, the sister company specialized in dials and a reference in the industry, developed a proprietary treatment that penetrates into the porous iron matrix. A galvanic rhodium plating seals the surface and enhances its silvery sheen without compromising the raw texture beneath. Blued hands and markers amplify the dial’s spectral character.

DIAL

Muonionalusta meteorite dial featuring a naturally occurring Widmanstätten pattern, formed through the ultra-slow cooling of the asteroid’s core. Each dial is one-of-a-kind, with a beveled date window machined directly into the meteorite. A proprietary anti-oxidation treatment developed with Cadranor penetrates the porous iron matrix and is sealed with galvanic rhodium plating—preserving the raw texture while enhancing its silvery sheen. Blued hands and markers complement the dial’s spectral appearance, with BGW9 Super-LumiNova applied to hands and indexes for low-light legibility.

SUSPENSION SYSTEM

Since the beginning of Formex in 1999, the patented Case Suspension System has been an integral part of Formex timepieces. Its two main functions are:

  • absorbs shocks to protect the mechanical movement from heavy impacts
  • adds to the comfort on the wrist by adapting to the wearer’s movements

Modeled with high-performance bikes and racing cars in mind, the Formex patented case suspension system works by integrating four springs between the upper and lower watch case. The result is the ultimate shock absorption system designed to protect the mechanical movement and deliver unparalleled comfort to the wearer.

This patented case suspension system brings form and function together for Formex Swiss watches. It’s functional, it’s state of the art engineering and it’s unquestionably unique - all in one watch.
