PFAS score
Casio · Waterproof Sports Watches
Casio Men's Digital Watch
Lower concern, typical digital watch with standard water-resistant treatment, no known PFAS risk.
Casio digital watches use conventional stainless steel, mineral glass, and resin construction without known Teflon-family coating coatings or specialty finishes that trigger PFAS concern. The water resistance likely comes from standard sealing methods rather than fluorinated water-repellent coating treatments.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
