Samsung Ridge Sport Band for Galaxy Watch4 & Classic 20mm Small/Medium- Silver
Unclear coating. Samsung doesn't disclose PFAS status.
This band is made for water resistance but lacks PFAS disclosure from Samsung. The coating composition is unknown and unverified by independent testing.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Samsung does not disclose whether the band's water-resistant surface treatment contains PFAS. Fluoroelastomer sport bands commonly rely on PFAS-based polymer coatings for hydrophobic performance. Skin contact with PFAS-coated elastomers during normal wear presents low acute risk but chronic exposure pathways are not quantified for this product.
Source, ATSDR ↗Azo dyes (color migration)
If the silver color is achieved via paint or dye rather than pigment-loaded elastomer, azo dyes could be present. Prolonged contact with skin, especially under perspiration and heat, may cause minor color transfer to wrists. Samsung does not specify the colorant chemistry for this band.
Coating degradation and leaching
Watch band coatings (any brand) can degrade after 1-2 years of daily wear, sweat exposure, and UV exposure, potentially releasing coating particles or residues. No specific recalls or complaints for Samsung Ridge bands are on public record, but normal lifespan degradation is expected.
What’s reassuring
Formaldehyde / VOCs
Elastomer and silicone sport bands do not require formaldehyde-based cross-linking resins. This hazard class is not applicable to non-fabric, non-ceramic band materials.
Source, ATSDR ↗Antimony in polyester
This band is elastomer-based, not polyester textile. Antimony hazard does not apply.
The full breakdown
What it's made of and why it matters
This band is constructed from fluoroelastomer or silicone, both elastomers designed for durability and water resistance on active wearables. Fluoroelastomer (Viton-type rubber) is chemically inert against skin oils and sweat; silicone is hypoallergenic and non-reactive. The water-resistant coating applied to the band surface is undisclosed by Samsung and may contain PFAS compounds to achieve water-shedding properties, though this is not confirmed in public documentation.
The brand's record and disclosure
Samsung does not publicly disclose material composition or chemical treatments for watch band coatings. The company has no published PFAS phase-out commitments specific to wearables. Samsung has faced no recalled sport bands for chemical safety issues in the Galaxy Watch line. Their transparency on elastomer sourcing and surface treatments remains minimal compared to some athletic apparel brands.
How it compares in its category
Replacement watch bands typically use the same core elastomer materials (silicone, fluoroelastomer, polyurethane) across brands. Samsung's sport band is mid-range in disclosure standards; some competitors (e.g., Garmin, Apple) publish more detail on strap coating chemistry. Most sport watch bands use proprietary water-resistant coatings, so PFAS ambiguity is sector-wide rather than brand-specific.
If you buy it
Rinse the band weekly under running water to remove sweat residue and prevent degradation at the connector points. Avoid prolonged exposure to direct sunlight, which can yellow silicone over time. Do not apply solvents, oils, or fragranced lotions directly to the band surface. Replace the band every 18-24 months or if you notice cracking, permanent staining, or connector loosening.
