Recently, Swiss watchmaker Rado has reintroduced the Anatom arched series watch, sparking great market enthusiasm. The Anatom series was first launched globally in late 1983 and has since become a signature representation of the Rado brand identity.
This pioneering collection introduced an innovative arched concept, featuring a convex (arched) sapphire crystal watch glass designed to naturally conform to the curve of the wrist when worn. Now, 40 years after its debut, the Swiss Rado Anatom arched series has once again returned to the spotlight.

Why Do Luxury Watch Brands Choose Sapphire Crystal Watch Glass?
1. Exceptional Hardness of Sapphire Crystal
Sapphire crystal boasts a Mohs hardness of 9, second only to diamond! Additionally, its scratch resistance far exceeds that of standard glass (Mohs hardness 5-6) and acrylic materials, making it highly resistant to everyday abrasions from objects like keys and sand particles. This extraordinary hardness and durability ensure that the watch glass remains clear and pristine over time, a key factor in keeping luxury timepieces looking timeless.
2. Superior Shock Resistance & Sealing Performance
High-end watches house intricate movements that must function reliably under demanding conditions. Sapphire crystal’s dense molecular structure provides impact resistance over 10 times stronger than ordinary glass. For instance, sapphire glass used in diving watches can withstand deep-sea pressure while ensuring a seamless fit with the watch case, guaranteeing waterproof performance.
3. Complex Manufacturing Process & Brand Prestige
Synthetic sapphire is refined from aluminum oxide crystals at an extreme temperature of 2000°C, then cut and polished using diamond tools. The production of a single sapphire crystal watch glass involves dozens of meticulous processes, making it significantly more costly than standard glass. This high level of craftsmanship serves as a distinctive hallmark separating luxury watches from ordinary ones.
4. Optical Properties & Aesthetic Appeal
Standard sapphire material has a light transmittance of no less than 84.5%, and with an anti-reflective coating, transparency can exceed 90%, ensuring clear visibility of intricate dial details. Some high-end brands even craft sapphire glass into arched, domed, or curved shapes, creating captivating optical effects. For example, Swiss Rado’s newly released arched series watch features a convex (arched) sapphire crystal watch glass, which the brand describes as a “timeless arch connecting the past and the future.”
