A Radiant Bronze Dial Highlighting Formex's In-house Dial-making Capabilities

For years, we’ve admired Formex for their commitment to material exploration and technical innovation. Because they manufacture many of their own components – including cases, dials, bracelets and clasps – the brand is able to push the limits of watchmaking further than many other independent brands.

When the Formex and Collective teams met at the 2022 Windup Watch Fair in Chicago, both were eager to pursue a special project together. In particular, Collective was keen to co-develop a watch that would resonate with enthusiasts by showcasing Formex’s distinct manufacturing capabilities. Just a few months later in New York, Raphael Granito, CEO of Formex, presented the Collective team with a prototype: a REEF diver with a radiant in-house bronze dial.

While bronze has often been used as a case material, it’s rarely found in dials. In fact, the development of the watch’s dial is the result of months of experimentation and prototyping at Formex’s in-house dial production facility. Given the rarity of bronze dials, Formex had to first develop its own processes and tooling in order to machine the dial blanks. Next, the team experimented with finishing in order to identify the best approach to highlight the unique properties of the alloy. After many trials, Formex settled on vertical brushing, which allows the dial to take on a variety of rich and vibrant hues depending on light sources and the angles from which it’s viewed. Finally, the dial is treated with a proprietary lacquer to prevent oxidation, ensuring it retains its original coloration. The result: A rich, glowing dial that only Formex can achieve.
