Description
Formex Swiss Made Watches, founded in 1999, is an independent family-owned watch manufacturer based in Biel/Bienne – a city considered the cradle of Swiss watchmaking. Drawing from a tradition of high-end watch production, it develops and produces models that meet the highest quality standards in the industry, complemented by unique technical solutions for enhanced functionality and comfort.
Thanks to an innovative distribution model, Formex offers an accessible entry into the world of luxury watchmaking for all who appreciate precise craftsmanship and exceptional artistry.

REEF 39.5mm Forged Carbon
The Reef 39.5 mm Forged Carbon model introduces a new material expression to the diving watch collection – combining a forged carbon dial and an interchangeable bezel with Formex's patented micro-adjustment system for exceptional comfort in any environment.
The dial, created by pressing carbon fibers under high pressure and temperature, reveals a naturally variable structure – each piece is completely unique. When light hits its surface, subtle changes in tones and textures appear, evoking the fluid and ever-changing character of water. The faceted date window at the 6 o'clock position, a typical Formex element, is integrated into the design quite naturally.
The forged carbon bezel follows the same philosophy. Its engraving is executed with extreme precision and then hand-filled with BGW9 Super-LumiNova Grade A luminescence for optimal readability in low-light conditions. Like all Reef bezels, it features a unidirectional 120-click mechanism and can be easily replaced by hand, without tools – for maximum versatility within the collection.

COSC Chronometer Certified Performance
When it comes to timekeeping accuracy, the gold standard is the COSC Chronometer certification. The Contrôle Officiel Suisse des Chronomètres (COSC) is the official Swiss chronometer testing institute, an independent body that certifies the precision and reliability of Swiss Made watches. The "Chronometer" designation can only be obtained for movements of the highest quality that successfully pass a rigorous 15-day series of tests. This means that the given caliber achieves the highest standards of mechanical reliability and accuracy.
Formex watches are powered by COSC Chronometer certified movements, ensuring the highest level of precision and performance in Swiss watchmaking. Only approximately 6% of all watches produced in Switzerland receive this prestigious designation, making them among the most accurate and reliable mechanical timepieces in the world.
