Formex Essence 41mm Automatic COSC with Blue Dial #0334.1.6631.100

This is a PRE-ORDER. We expect to ship the pre-orders the end of November.

Formex unveils the Essence 41mm COSC with four signature dials, evolving the recent and already sold out “Space Ghost” limited run into a lasting chapter of the collection. The 41mm case design slots neatly between the 39mm and 43mm models, reflecting community feedback and hitting the sweet spot for versatility, wearability, and wrist presence. It expands the Essence platform with a new fit and updated proportions, while retaining the modular system of interchangeable straps and bracelets.

True to Formex’s performance ethos, the latest evolution of the Essence platform debuts a re-engineered butterfly clasp – a new patent – that builds on the micro-adjustability of the previous generation to offer even greater all-day comfort and security. This new clasp allows for adjustability without the need to open the clasp, even to tighten the bracelet. The innovative system requires more force to pull the adjustment out than it requires to push it back in and thus shortening the length of the bracelet. More subtle but no less significant: a redesigned screw-down crown system that integrates seamlessly with Formex’s patented Case Suspension System; and new link-fastening screws for the steel bracelet – a step change in the assembly of this critical component, ensuring greater precision, durability, and wear resistance over time.

“The new case size on the Essence 41mm is in no small part also the result of feedback from our community. It fits perfectly between the 39mm and 43mm models, offering a balanced feel and fit for a wider range of wrist sizes – with the same versatility and performance. Speaking of which, our new micro-adjustable butterfly clasp is a real game-changer, offering more wrist fit flexibility and comfort as well as seamless bracelet aesthetics.”
Raphael Granito, CEO of Formex

New Size, Same Values and Versatility

The Essence 41mm COSC retains the hallmark design elements of Formex’s bestselling collection, crafted in durable 316L stainless steel, and is now offered in a new, versatile size that complements the existing 39mm and 43mm models. Versatility naturally extends to the complete range of straps and bracelets already available for all Essence models. Here, the quick-release system allows users to easily swap between leather, rubber, nylon and stainless steel and back again – in no time and without tools.

Inside: the tried and trusted – and beautifully decorated – Sellita SW200-1 automatic movement, known for its Swiss Made reliability and precision. With COSC-certification for chronometer-grade accuracy, this workhorse engine ensures the same high standards of performance and dependability that Formex is synonymous with.

Four Colorways for Character

Offered in four dial variations—each defined by its own finishing treatment—the Essence 41mm COSC preserves the collection’s hallmarks: precisely CNC-milled horizontal lines, applied indices and hands with brushed surfaces and mirror-polished edges, and deep-filled BGW9 Super-LumiNova for clear reading after dark. At 6 o’clock, a beveled date window, a design element found throughout the Formex collection, preserves balance and visibility from varied angles, with a color-matched wheel on each dial variant.

Gamaret – Inspired by the rich red of a Swiss wine grape that has been developed specifically to thrive in an alpine climate, the “Gamaret” dial uses a hand-applied gradient to create a tone that recalls the swirl of wine in a glass—bright at the center, darkening toward the edges. The effect is vibrant and expressive, perfectly balanced by the black ceramic setting. 

Dégradé – A warm brown dial with a light sunburst finish enhanced by a hand-applied gradient, shifting from silvery tones at the center to near-black at the edge. The gradation blends seamlessly with the ceramic case, giving the watch understated sophistication and depth.

Blue – A bestseller in the Essence steel line, the blue dial reveals its vertical brushing most clearly. Depending on the light, it shifts from nearly black in shadow to a vibrant navy in sunlight—a dynamic, versatile character that reinforces the watch’s bold presence.

White – High-contrast by design: a crisp white lacquer dial set against full black ceramic for instant, at-a glance legibility. Gunmetal hands, indices, and logo read as black in low light, then catch the light to reveal polished bevels and brushed facets that guide the eye. The pared-back layout and precise grooves keep every indication clear and precise.
Together, the four dials showcase the breadth of the Essence identity—each with its own character, yet all unmistakably Formex.

Formex’s New Micro-Adjustable Butterfly Clasp

Evolution at work. The Essence 41mm COSC is the first model to feature Formex’s next-generation micro-adjustable butterfly clasp, designed for the steel bracelet version. This newly patented system builds on the benchmark-setting concept introduced in 2019 and developed in close collaboration with sister company Dexel – an industry-leading bracelet and buckle specialist located just next door.

In the previous version, opening and closing required a specific sequence – short segment first, then the longer one – and the 4mm micro-extension could only be set with the bracelet open. The new clasp eliminates those constraints, offering quicker, more intuitive adjustment on the fly with a new variable force system developed specifically for this model.

Formex’s ongoing partnership with Dexel continues to shape its leadership in ergonomic fastening solutions. The latest clasp evolution is intuitive, tool-free, and designed for even quicker, easier, and more precise wrist fit micro-adjustments.

Formex’s new micro-adjustable butterfly clasp system at a glance:

• Three-position micro-adjustment: 0mm, 3mm, and 6mm – vs. 0mm and 4mm previously.
• Fully integrated into the bracelet for smooth, seamless aesthetics.
• Micro-adjustment in and out operated in the closed position – for greater ease and security.
• Calibrated resistance: extending the clasp requires more force than retracting it, improving control and enhancing comfort with quick and seamless adjustment.
• Gapless extension: even in the extended position there is no gap at the buckle (as with the previous system) – preserving the bracelet’s visual integrity and wear comfort.

New Screw-Down Crown

The Essence 41mm COSC also introduces more subtle but no less significant innovations. The new screw-down crown system enhances security and prevents the crown tube from accidentally deforming. Seamlessly integrating it with the patented Case Suspension System was an engineering challenge. Traditionally, the Case Suspension System is designed to allow the crown to move with the case, adapting to the wearer’s wrist movements for increased comfort and shock absorption. Adapting this flexible system to accommodate a screw-down crown, which requires a more rigid, fixed connection for mechanical resistance, required extensive redesign and testing to ensure that the crown could securely lock in place.

Re-engineering the closure system led Formex to take a long, hard look at the rest of the bracelet. And it turns out there’s a better way when it comes to the screws that hold the links in place.

New Bracelet Screws

Alongside the new micro-adjustable butterfly clasp system, the Essence 41mm COSC also features a redesigned link-fastening screw for the stainless steel bracelet. Instead of the old-school approach of using a drop of threadlocker or a composite threadlocking treatment to keep screws from loosening over time – a non-trivial concern given the constant movement, shocks, and stresses the bracelet endures – Formex opted for a purpose-designed screw with an offset thread. This allows the moving part of the link to articulate freely, while the threaded section remains securely isolated from mechanical stress. No threadlocker is needed, and more importantly, there is no risk of the bracelet screws coming loose. A small detail that makes a big difference: improved bracelet precision, durability, wear resistance – and peace of mind.
