Founded in Biel/Bienne and revitalised in 2016 under the leadership of Raphaël Granito, Formex is appreciated for its engineering-driven watchmaking, ergonomic case design and modularity. Known at first for its motorsport roots and patented case suspension systems, the brand has gradually defined its identity with the Essence and Reef collections, offering well-executed watches with interesting technical solutions at accessible pricing. The Reef collection, presented in 2020, comprises distinctive, robust 300m dive watches with interchangeable bezels and straps, all powered by COSC-certified movements. The more compact, 39.5mm Baby Reef series (2023) is now one of the brand’s most compelling everyday divers.
The new Reef 39.5 Forged Carbon builds on this foundation but introduces a different aesthetic. While carbon is often used for weight reduction or performance claims, Formex focuses on its visual and tactile qualities. The dial and bezel are executed in forged carbon, a material created by compressing short fibres under heat and pressure. Integrating this material required adaptation. The vertically brushed dial sits on a treated base; the signature bevelled date window at 6 o’clock is preserved with precise layering. On the fully functional, 120-click dive bezel, numerals are engraved using a femtosecond laser and filled by hand with lume.
Beyond aesthetics, the tech specs remain unchanged. The applied indices and hands with Super-LumiNova ensure visibility. The 39.5mm case (11mm thick, 45.5mm lug-to-lug) is compact and balanced, with a stainless steel exterior and titanium container. A guard protects the screw-down crown, a sapphire crystal with AR coating, and the caseback is solid. Water resistance is rated at 300m.
Power comes from the COSC-certified Sellita SW300-1, an alternative to the ETA 2892, beating at 28,800 vibrations/hour and delivering a 56-hour power reserve.
Versatility continues to define the series. The interchangeable bezel system allows the forged carbon insert to be swapped for ceramic or steel alternatives, while quick-release straps, steel, rubber, leather or nylon, paired with Formex’s fine-adjustment clasps, offer adaptability in everyday use. The Reef 39.5 Forged Carbon is priced from EUR 1,960 on a strap and EUR 2,070 on a bracelet, with an initial batch limited to 100 pieces.
