Over the Hill: Exploring High‑Tech Ceramic on Its 40th Anniversary
High‑tech ceramic has become a cornerstone of modern watchmaking, offering both exceptional durability and striking aesthetics. Rado pioneered its use, beginning with a sapphire crystal case and advancing to fully ceramic cases and bracelets with the 1986 Integral. Over the decades the brand refined the material through processes such as coloration, injection molding, and a unique self‑polishing technique that uses ceramic chips, ultimately achieving a metallic appearance without any metal coating. The development reached a breakthrough with plasma treatment, where extreme temperatures trigger a chemical transformation that gives the ceramic a grey, metal‑like finish. The production workflow starts with high‑purity zirconium oxide powder, which is combined with pigments and binders, then formed into a feedstock that is injection‑molded into oversized blanks to allow for shrinkage. After molding, the parts undergo a chemical bath and a prolonged high‑temperature bake to remove the polymer binder, followed by a ceramic‑on‑ceramic polishing process. These steps result in a pure, dense ceramic component that can be machined and finished to exacting standards. Rado’s continuous innovation, recognized by multiple design awards, culminates in the 40th‑anniversary Integral, which blends the classic silhouette with modern upgrades while showcasing the enduring impact of high‑tech ceramic in horology.
