Formex Watch: Airfield Automatic Tarmac Grey

Formex: the AirField Automatic Tarmac Grey, a hardened titanium aviator watch

The Formex AirField Automatic Tarmac Grey translates the lightweight architecture of the Field collection into the world of aviation watches. Its 40mm case made of hardened Grade 2 titanium surrounds a finely grained grey dial designed to maximize legibility. The large hands and recessed Arabic numerals give the Formex AirField Grey an identity directly inspired by cockpit instruments.

The Formex AirField Tarmac Grey features particularly well-balanced proportions with a 40mm diameter, 46.6mm lug-to-lug, and 10.6mm thickness. Its Grade 2 titanium case undergoes a hardening treatment that brings its surface hardness to approximately 900 Vickers, while maintaining a weight of only 54g for the case alone. An anti-reflective sapphire crystal protects the dial of this AirField Grey, while a screw-down crown and 150-meter water resistance reinforce its tool watch character.

The Formex AirField Tarmac Grey is powered by the new Sellita SW200-2 Power+, a Swiss Made automatic movement with 26 jewels, operating at 28,800 vibrations per hour / 4 Hz. This evolution of the SW200 extends the power reserve to 65 hours while maintaining the display of hours, minutes, seconds, and the date. The date disc, matched to the color of the dial, allows the AirField Grey to maintain a monochrome and highly legible presentation.

The Formex AirField Tarmac Grey is offered on a black nylon strap with a Velcro closure, which is lightweight, elastic, water-resistant, and washable. Its quick-release spring bar system allows for tool-free strap changes. The solid case back, decorated with a radial engine and a propeller, extends the aeronautical theme of this AirField, which was designed, developed, and assembled by Formex in Biel/Bienne, Switzerland.

About the Formex brand

Founded in Switzerland in 1999, Formex develops its watches in Biel/Bienne with an approach strongly oriented toward engineering, ergonomics, and technical materials. The brand is particularly known for its use of titanium, ceramic, carbon fiber, and for various patented systems designed to improve the comfort and daily use of its watches.

With the Formex AirField Automatic Tarmac Grey, the brand adapts the lightweight and functional base of its Field family to a more assertive aeronautical aesthetic. The AirField Tarmac Grey also introduces the Sellita SW200-2 Power+ caliber with its 65-hour power reserve into this hardened titanium architecture. This new Formex thus maintains the utilitarian approach of the Field while developing a unique identity inspired by cockpit instruments.
