In short: Silicone/Bioceramic is the best choice for sports: sweat-proof, salt-water resistant, and UV-stable, designed for intense active use.
Why silicone dominates for sports
Light, flexible, moisture-resistant — premium silicone doesn't retain sweat and dries quickly between sessions.
Bioceramic, an alternative for light sport
For moderate activities (walking, yoga, occasional cycling), Bioceramic Monochrome stays water-resistant without sacrificing looks.
To avoid during sports
Steel cases (Rosegold, Silver Premium, Diamond) aren't designed for intense physical activity — save them for calmer occasions.
