Formex AirField 40: A Pilot Watch Without the Vintage Costume

Pilot watches often arrive with a story about the past: wartime specifications, cockpit instruments, oversized cases or a historical reference that explains why the design looks the way it does. The Formex AirField 40 takes a different route. It starts with the brand’s existing Field platform and asks what an aviation watch needs in 2026 rather than what one looked like decades ago.

That makes the AirField interesting for collectors who like tool watches but do not necessarily want historical costume. The case architecture is contemporary, the dial uses familiar pilot cues without copying one famous template, and the practical specifications are aimed squarely at daily wear.

The case is deliberately not the headline

Formex uses a 40mm Grade 2 titanium case, officially listed at 10.6mm thick and 46.6mm lug-to-lug. The case head weighs 54 grams and is hard-coated to approximately 900 Vickers. A screw-down crown and 150 metres of water resistance give the watch considerably more everyday versatility than the aviation theme strictly requires.

The important point is that Formex did not enlarge the Field case simply to make the AirField look more “pilot-like.” Short lugs, low weight and a restrained profile remain. For buyers, that is a stronger practical decision than using diameter as a historical styling cue.

The aviation language is functional

The dial is where the AirField separates itself from the regular Field. Broad sword-shaped hands, recessed Arabic numerals, a triangle flanked by two dots at twelve and a seconds hand with an aircraft-shaped counterweight make the purpose immediately legible. The date remains at six with a colour-matched disc rather than being removed for stylistic purity.

There are four base references: Jet Black 0661.1.6526, Horizon Blue 0661.1.6536, Tarmac Grey 0661.1.6546 and Desert Sand 0661.1.6556. Strap-specific suffixes vary with configuration.

Our preference is Jet Black if the goal is maximum instrument-like clarity. Desert Sand is more distinctive, but its blacked-out luminous treatment makes the aesthetic choice more obvious. Horizon Blue offers the easiest route away from the military-tool-watch look, while Tarmac Grey sits between the two.

The movement makes the watch easier to rotate

Inside is the Sellita SW200-2 Power+, with 26 jewels, a 4Hz frequency and approximately 65 hours of power reserve. That is useful in a collection because the watch can come off the wrist for more than two days without immediately becoming a reset exercise.

The movement is not exotic, and that suits the watch. A tool-oriented automatic benefits from familiar architecture and practical autonomy more than it needs a decorative movement story.

Straps are part of the proposition

The lightweight nylon/Velcro option keeps the watch firmly in tool-watch territory. Leather changes the presentation and can be paired with Formex’s carbon-fibre composite deployant clasp, which offers 7mm of gradual fine adjustment. Both systems use quick-release attachment.

Launch coverage quoted CHF 830 or EUR 950 on nylon and CHF 970 or EUR 1,075 on leather with the deployant clasp. Those are launch figures, not a universal current retail price; Formex’s present online pricing varies by market and configuration.

The 777CHRONOS view

The AirField works best when judged as a contemporary tool watch rather than as an attempt to enter the heritage-pilot category. It borrows the visual grammar of aviation instruments, but the underlying decisions—hardened titanium, compact dimensions, 150-metre water resistance, quick-change straps and useful power reserve—belong to modern everyday ownership.

For a buyer, we would choose the dial first, then the strap system. The case and movement are common to the family, so the real difference is how much aviation character you want the watch to show. The AirField’s strongest argument is that it does not need an invented historical narrative to justify being a pilot watch.
