Formex has always been easier to understand on the wrist than in a catalogue.
The Biel-based independent built its following with accessible sports watches, unusually engineered cases and bracelet hardware that feels more expensive than the price tags suggest.
The new Aria changes the scale of that conversation, pairing Formex’s manufacturing instincts with a high-spec micro-rotor movement and a retail price that puts the brand in a more serious arena.

At a glance
- Formex has introduced the Aria, its most ambitious watch to date and the first model outside Horage to use the latest-generation K2 micro-rotor architecture.
- The 40mm titanium watch is just 6.9mm thick, weighs 78 grams with its bracelet and uses the FX01 calibre with a silicon escapement, 72-hour power reserve and COSC certification.
- Priced at £6,500, the Aria sits well above Formex’s established collections and signals a deliberate move into higher-end independent watchmaking.
A movement-led Formex for the first time
Formex’s reputation has largely been built from the outside in.
The brand is owned by the Granito family, who also own Dexel, a specialist manufacturer known for bracelets and clasps made to exacting tolerances.
That background helps explain why Formex watches often feel mechanically considered even before the movement enters the discussion.

The Essence collection, with its case suspension system and sharply machined components, made that approach visible, but much of the brand’s catalogue has relied on Sellita calibres.
Those movements are dependable and appropriate at Formex’s more accessible price points, yet the Aria takes a different route.
Rather than beginning with the case, bracelet or clasp, Formex built the watch around a movement supplied by fellow Biel company Horage.

The calibre is known here as the FX01, and it comes from Horage’s latest K2 micro-rotor platform.
That matters because Horage has been selective with the K2, making Formex the first brand outside Horage itself to use the movement.
“Working with like-minded brands is always the goal,” Horage COO David Sharp said, pointing to the shared engineering culture and Biel proximity that made the collaboration a natural fit.

The FX01 calibre sets the tone
The FX01 is compact in the way collectors tend to notice immediately.
At 2.9mm thick, the micro-rotor movement allows the Aria to stay extremely slim without flattening the personality of the watch.
The specification is unusually strong for an independent sports watch at this level, with a full silicon escapement, LIGA components, a 72-hour power reserve and COSC certification.

Formex has also given the calibre a more contemporary visual identity rather than leaning on the expected decorative language of Swiss watchmaking.
The bridges are finished in galvanised black gold, with brushed surfaces, hand-bevelled edges and laser-cut openings that suit the watch’s technical character.
It’s not decoration for nostalgia’s sake.

The movement feels like the starting point for the entire object, which is precisely the shift Formex owner Raphael Granito wanted to make.
“The FX01 calibre costs us roughly eight times what we pay for the movements in our Essence collection,” Granito said. “And when you’re starting from that base, the only right path in our eyes was to make sure every other component in the watch lives up to it.”
Titanium, curves and a bracelet with real substance
The Aria measures 40mm across and only 6.9mm thick, a combination that keeps it modern in diameter but notably refined in profile.

It’s made in titanium and weighs 78 grams including the bracelet, which should give it the kind of lightness that makes slim watches feel even more deliberate.
Visually, the Aria steps away from some of Formex’s more angular language.
The case and bracelet use smooth, pebble-like curves that run from bezel to clasp in one flowing line.

The bracelet is central to the watch’s personality, with brushed links and polished bevels that show Dexel’s influence without turning the design into a display of manufacturing for its own sake.
The dial carries the same architectural thinking in a quieter way.
The indexes sit on raised platforms, while the surrounding surface appears to fall away from them, creating depth without adding thickness.

At six o’clock, a small seconds display is finished with a bold sunburst engraving, and the dial is offered in blue, green and grey.
The price move is the story
At £6,500, the Aria is a major jump for Formex.
The Essence line has traditionally occupied the mid-£1,000s to mid-£3,000s range, depending on configuration, so this isn’t a gentle step upward.

Granito frames the price as the result of the watch rather than the brief.
“It was the FX01’s architecture that opened up the design space entirely,” he said. “We didn’t sit down with a target price and work backward. We let the creativity run free, worked with the best people we could find, and refused to let budget be the limiting factor.”
He added that Formex’s margin has not changed, describing the brand’s usual retail approach as a three-times multiplier from manufacturing cost.

That transparency is important because the Aria now lives near watches with far broader recognition.
Its buyer is unlikely to be someone cross-shopping purely by logo or heritage story.
This is more likely a collector who already owns the obvious icons and wants something technically interesting, light on the wrist and less predictable in the room.

The Aria doesn’t abandon what made Formex interesting in the first place.
It takes the brand’s comfort with precision hardware and gives it a movement worthy of the same attention, which is exactly why this watch feels less like an expensive outlier and more like the beginning of a new chapter.
