Withings Move
Activity tracker with minimal PFAS concern; lower risk profile.
Withings Move is a hybrid smartwatch with stainless steel case and plastic band lacking any water-repellent treatment. Standard electronics pose minimal PFAS exposure.

What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Silicone band degradation and skin irritation
Silicone is generally well-tolerated, but prolonged contact can cause localized irritation in sensitive individuals, particularly if the band retains sweat, bacteria, or debris. Regular cleaning and occasional band removal reduce this risk.
Battery leakage (internal lithium-ion cell)
The Move contains a sealed rechargeable battery. If the device is crushed, dropped, or punctured, internal electrolyte leakage is theoretically possible but uncommon under normal consumer use. Environmental disposal hazard is greater than personal safety hazard.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Electronic components (solder, flux, circuit board resins)
Internal electronics are sealed and not in contact with skin during normal use. Risk of exposure is negligible unless the device is deliberately opened or damaged.
Stainless steel nickel leaching
High-quality stainless steel used in consumer electronics typically contains low nickel percentages and does not leach measurable amounts under normal skin contact. Withings does not disclose alloy composition, but nickel allergies are rare enough that this is not a practical concern for most users.
Microplastic shedding from band material
Silicone does not fragment into microplastics during normal wear or washing. Risk is absent unless the band is physically torn and degraded, which is not typical for this product class.
The full breakdown
What it's made of and why it matters
The Withings Move uses a stainless steel case, which is chemically inert and does not leach metals under normal wear conditions. The band is silicone or elastomer-based, materials that do not off-gas volatile organic compounds at body temperature and are not known to break down or migrate into skin. Electronic components are sealed internally, limiting exposure to solder, flux, or circuit board materials during normal use.
The brand's record and disclosure
Withings does not publicly disclose detailed material safety certifications or third-party testing results for the Move. The company is silent on PFAS, though the product's minimal fabric and coating content makes deliberate PFAS use unlikely. No recalls, toxicity complaints, or regulatory warnings have been publicly documented for this model.
How it compares in its category
Activity trackers typically use either rubber/silicone bands or fabric straps; the Move's silicone band presents lower concern than some fabric options treated with water-resistant coatings that may contain PFAS or dyes. Stainless steel cases are industry standard and among materials with lower concern for PFAS contamination. The Move avoids plastic-heavy designs that carry microplastic or BPA concerns during disposal.
If you buy it
Clean the band regularly with mild soap and water to prevent bacterial or fungal growth in skin contact areas. Avoid prolonged exposure to harsh chlorine or salt water, which can degrade seals over time. The device is not designed to be disassembled; do not attempt to open the case. Battery replacement typically requires manufacturer service; plan for eventual disposal or recycling rather than component replacement.
