Formex has introduced the Aria Manufacture Chronometer. The 40mm timepiece houses the FX01, Formex’s new micro-rotor movement developed in collaboration with Horage. At 6.9mm thick and weighing just 78 grams, this represents the brand’s thinnest and lightest offering to date.
The case construction centres on Grade 5 titanium, the same aerospace-grade alloy used in surgical and marine applications. Grade 5 titanium offers roughly 40% less weight than steel whilst maintaining comparable strength. Each case undergoes individual hand-brushing to follow the organic curves of the design, which Formex describes as appearing shaped by natural elements over time.
Three dial options define the Aria Manufacture Chronometer collection. The Selva Green variant carries forest-floor tones with amber luminous accents, whilst the Ardesia Grey offers cooler, architectural slate tones. Meanwhile, the Denso Blue provides a dense, matte navy finish that absorbs rather than reflects light. Each dial features stamped brass construction with matte lacquer and bevelled indices positioned on raised platforms.
The FX01 calibre represents a significant technical achievement for the brand. This micro-rotor movement measures 2.9mm thick compared to 4.6mm for conventional automatics like the Sellita SW200-1. The tungsten micro-rotor generates 55% improved winding efficiency despite its compact size, delivering a 72-hour power reserve. Additionally, the movement incorporates a full silicon regulating system including the hairspring, escape wheel and pallet fork.
Formex has helped to engineer several performance enhancements into the FX01. The flexible geartrain pinion eliminates backlash during time setting, providing immediate crown response for precise synchronisation. Furthermore, Horage’s silicon components offer anti-magnetic properties, corrosion resistance and reduced friction compared to traditional steel parts. Each movement receives individual COSC chronometer certification.
The integrated titanium bracelet continues the organic design theme with hand-brushed finishing throughout. Each link features subtly curved surfaces that provide comfort whilst maintaining the flowing aesthetic. Mirror-polished bevels on both case and bracelet create deliberate light reflection contrasts against the brushed surfaces.
Production of the Formex Aria Manufacture Chronometer founders edition is limited to up to 100 pieces for each of the three dial variants. It’s technically made to order within the 100-piece limit during the pre-order window. Delivery is scheduled for September 2026, with pricing set at CHF 5,900 or $7,900 (approx. £5,600).

I had an odd reactio to this watch. When i first saw the ad (in your mag) it was the brown version and I thought, ok, thats pretty nice for Formex, i like the rustic quality. A design step up for them. But then when i saw it came in three colors it felt cheaper. I dont know if that makes sense but there are too many colors today for most brands.
Very different from what we expect from Formex. It is a truly stunning watch. If it had been more than splashproof I would have ordered one in a flash.
The watch industry across the piece is saying a lot about this watch, but you need to check carefully as there is much that could be misleading.
It is not a “sports” watch, confirmed by the modest 30m of water resistance. Ignore those who tell you it has 100m WR.
It is not an “in-house” movement, it is bought in.
Grade 5 titanium is not superior to grade 2, but they do have slightly different qualities which enable different priorities.
£6.5k is a chunk more than £5.6k.
I like the watch.
