The Swiss diving watch Formex Reef 42 Automatic Chronometer Bronze Dial 2200.1.6382.100 stands out at first glance with its distinctive bronze dial and recognisable case. It is a modern diving watch suitable for any occasion, characterised by clean lines, high durability and excellent legibility.
Bronze has often been used as a case material, but is rarely used to make dials. The bronze dial is the result of months of experimentation and prototyping by Formex. The result is a unique, radiant dial that changes its appearance depending on the light falling on it. The dial surface is treated with lacquer to prevent oxidation.
The case of the Formex Reef 42 Automatic Chronometer is made of steel with a brushed finish, complemented by polished surfaces. The case features a unidirectional rotating diving bezel with minute markings and a ceramic insert. Despite its robust appearance, the case is only 11,4 mm high (it feels more like 9,5 mm).
The case is complemented by a steel strap with a folding clasp featuring fine micro-adjustment and up to 10 mm of length adjustment. The strap has a quick-release system, making it easy to change without tools.
The watch is powered by a Sellita SW300-1 automatic mechanical movement (Chronometer Grade) with COSC certification and a power reserve of approximately 56 hours. The movement operates at 28800 vibrations per hour and offers winding via the crown, a stop-seconds function when setting the time (hacking) and a date at 6 o'clock. The watch has a water resistance of 300 m (30 ATM), making it suitable for water activities, including diving. The high water resistance is supported by a screw-down crown and case back. The case diameter is 42 mm, making the watch suitable for most men's wrists.
The characteristic features of the Formex Reef 42 Automatic Chronometer include a distinctive, legible dial, high water resistance and a clasp with fine micro-adjustment. The clear dial is protected by a highly scratch-resistant sapphire crystal with an internal anti-reflective coating. Luminescence (BGW9 Super-LumiNova) on the hands and indices improves legibility in low-light conditions. The Formex dial has a brushed finish and hand-applied, raised triangular indices that slope from the edges towards the centre of the dial. The overall appearance is complemented by a carefully designed date display at 6 o'clock. The watch is versatile, with features suited to sports, water activities and everyday use.

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.
