The Swiss watch Formex AirField Automatic Jet Black Khaki Green Nylon-Velcro 0661.1.6526.877 is based on the proven construction of the Field series, complemented by distinctive elements inspired by aviation. They retain the characteristic lightweight and durable titanium case with a diameter of 40 mm, but now come with a dial and hands designed with an emphasis on quick orientation and easy legibility. The black Jet Black version is the most restrained variant of the new AirField collection and its appearance resembles instruments in an aircraft cockpit.
The watch case is made of grade 2 titanium with a specially hardened surface reaching a hardness level of 900 Vickers (compared to the original hardness corresponding to 145 Vickers), which significantly increases scratch resistance. All this while maintaining low weight (the case weighs only 45 grams), high comfort and the hypoallergenic properties of titanium.
The pilot theme of the watch is also reflected in the design of the titanium case back with a relief of a star-shaped aircraft engine with a propeller.
The most distinctive change compared to the Field series is the new dial with aviation motifs. Its finely grained black surface is complemented by recessed Arabic numerals and wide sword-shaped hands. At the 12 o’clock position there is the pilot-style triangle with two dots, which makes quick orientation easier. An interesting detail and reference to aviation is the counterweight of the seconds hand in the shape of an aeroplane.
The dial is protected by a sapphire crystal with internal anti-reflective coating and high scratch resistance. Better legibility in reduced light conditions is ensured by luminescence (Super-LumiNova® BGW09 Grade A) applied to the hands, numerals and indices. The recessed numerals and hour indices give the dial visible depth. Everything is underlined by the sensitively designed date display at the 6 o’clock position, with a ring in the colour of the dial.
The watch is powered by the mechanical automatic Sellita SW200-2 Power+ movement with a power reserve of around 65 hours. The movement with a frequency of 28800 vibrations per hour naturally offers winding via the crown and a seconds stop function when setting the time (hacking).
The case is complemented by a very comfortable green elastic nylon strap, finished with Velcro, which allows comfortable adjustment to the wrist.
The water resistance of this watch is 150 m, supported by a screw-down crown and case back. The case diameter is 40 mm, so the watch fits most men’s wrists very well.
A leather strap can be purchased for the watch, finished with a carbon folding clasp with an innovative fine micro-adjustment system in a range of 7 mm. You can easily adjust the length by pressing the side button without needing to take the watch off your wrist.
You can also find the watch under the designation Formex 0661.1.6526.877

Formex Watches is an independent Swiss watch manufacturer based in Biel-Bienne, the cradle of Swiss watchmaking, where the entire production process takes place from design, development, assembly and testing of all watches. The company was founded in 1999 with the aim of producing watches that will meet the highest quality standards. The brand is known for the use of high-tech materials and the development of unique improvements and functions, leading to the technical perfection of the watch and an increase in wearing comfort - for all of them, let's name the Case Suspension System, a patented suspension system of the case, protecting the movement of the watch during impacts and increasing comfort on the wrist.
The Formex brand was founded by two brothers, watchmakers and watch enthusiasts who wanted to combine their passion for watches with their love of motorsport. High resistance is therefore typical for the design of the watch, suitable even for extreme conditions. It is aimed not only at watch lovers, but also at all athletes, outdoor enthusiasts and adventurers who require functionality and high reliability.
Formex is a combination of the French words "forme" and "extrème", loosely translated as extreme form/shape. All watches assembled at the brand's headquarters in Biel-Bienne meet the strictest requirements of the Swiss Made label. Every single piece goes through careful quality control and testing. Formex watches reflect love for watchmaking, high quality workmanship, innovative approach, relentless development, use of special materials and exceptional craftsmanship.
Helveti.eu is an authorized retailer, specialist and certified expert of the Formex brand.
