What We Know
The last time I covered something from Formex was over a year ago, when the brand released a highly finished, full-ceramic sports watch, complete with a ceramic bracelet and even a ceramic micro-adjust clasp, at an unrivaled price point. Today, the brand continues its upmarket trend with a brand-new watch design called the Aria.
The Aria takes the form of a broad, integrated-bracelet design in full grade 5 titanium. The 40mm case feels broader than normal, thanks to an impressively thin case height of 6.9mm, even though the lug-to-lug is still quite reasonable at 45.45mm. While the silhouette gives a smooth look, there’s quite a bit of contrasting finishing going on here, with brushing of the titanium case and bracelet links done entirely by hand. Though the styling certainly leans towards its identity as a bold sports watch, there’s a lot of subtlety in the design, for example, with the individual bracelet links being slightly curved or the extra dimensionality of the layer of titanium peeking out from each link’s milled-out spaces. The clasp includes Formex’s proprietary micro-adjust system, which provides extra space on both sides of the bracelet by pulling or pushing each side.
There are three dials for the Aria: “Selva Green,” “Ardesia Grey,” and “Denso Blue.” All three have a certain muted look to the hue, matching the slightly darker nature of titanium. Dimensionality is achieved through contrasting indices in rose-gold coloring, set on applied raised platforms, with a subtle radial line extending to each on the dial surface. A closer look reveals that the dial base itself is also curved, giving another subtle touch to the overall design.
Inside the watch is the brand’s first departure from more standard Sellita-based calibers, with an exclusive COSC-certified Caliber FX01 produced through Horage. The watch’s thinness is thanks to the microrotor construction (with the caliber a mere 2.9mm thick). Rafael Granito, the CEO of Formex, tells me that the tungsten microrotor actually gives the watch one of the most efficient winding systems in the market—about one hour of wear can yield ten hours of power in the mainspring, adding to the total of 72 hours of power reserve.
The FX01 features a silicon regulating system, from the hairspring to the escape wheel and pallet fork, but the most interesting part to me is the flexible geartrain pinion, which eliminates any free play between the gear teeth and thus allows for a much more responsive and precise feeling when setting the time through the crown. The movement bridges are plated in galvanic black gold, with grained textures executed by laser engraving and hand-brushed beveling.
Granito tells me that the brand has secured 100 movements for the Aria’s debut, meaning total production across the three dial colors will be limited to this quantity during this introductory phase. Quantity is not limited between the colorways, but total production will be capped at 100 pieces. The “founders edition” of this Formex Aria Manufacture Chronometer is priced at $7,900.
What We Think
Like I said in my review of the Essence Ceramica last year, this new watch from Formex is certainly an ambitious endeavor, and the design continues to exhibit the brand’s curious duality. On the one hand, the finishing on this case and bracelet in grade 5 titanium really feels unparalleled for the price point. In person, this watch feels great, and though it wears quite broad thanks to the ratio of diameter to case height, it wraps around the wrist quite nicely and is extremely light thanks to the choice of metal. And the movement, though very strong technically, is, of course, not necessarily new, as it’s based on Horage’s pre-existing K2 architecture. Between the well-finished grade 5 titanium construction and the departure from Sellita-based movements, the rationale for the near-eight-thousand-dollar price point becomes a bit clearer. There’s not really a full-titanium microrotor sports watch in this segment, certainly not one with this feature set, construction, or finishing.
On the other hand, it’s priced squarely in a bracket that opens up many possibilities across the market, especially for those looking for brands with a lot more heritage. So the question is, who is this watch for? It’ll be hard to imagine even the nerdiest of watch nerds picking this over a titanium Spring Drive Grand Seiko, in my opinion. I ask Granito this, and he offers an alternative perspective, one that I think is fair given the success of Formex’s growth over the years through its e-commerce platform and retail network. He tells me that watches like these are for those who might be a little less heritage-minded and more technically minded, with many of the brand’s customers wanting something that feels well-built, without caring about what the name on the dial might be. And for the brand, something like the Aria serves as a continued demonstration of what Formex’s manufacturing capabilities can achieve, which is why I’ve always found myself curious about what the brand is up to.
