Withings ScanWatch 2 Hybrid Smartwatch
No PFAS disclosure available; likely water-repellent coating-treated.
Withings hasn't released public information about PFAS for this hybrid watch. Water resistance in watches often involves water-repellent coating coatings that may contain PFAS.

What Withings ScanWatch 2 Hybrid Smartwatch is made of, ingredients and materials
The ScanWatch 2 case is stainless steel and sapphire crystal, both chemically stable and non-leaching under normal use. The elastomer (rubber) bands are the primary material variable, elastomers can contain plasticizers, UV stabilizers, and dyes, but Withings has not disclosed specific formulations. Water resistance to 50m is achieved via sealing and likely water-repellent coating (water-repellent coating) surface treatment, which commonly relies on PFAS chemistry (as flagged in the PFAS grade). No information is publicly available on whether the bands contain phthalates, heavy metal colorants, or other processing additives.
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.
water-repellent coating (water-repellent coating) treatment chemistry
Water resistance is likely achieved with fluorinated water-repellent coating, commonly PFAS-based, but Withings does not disclose the specific chemistry or whether it meets PFOA/PFOS restrictions.
Skin sensitization from band contact
Elastomer dyes and processing residues can trigger contact dermatitis in sensitive individuals, particularly with daily wear and sweat accumulation; risk is typical for rubber wearables but mitigated by band washing.
Coating degradation and microparticle release
Over years of wear, the water-repellent coating and band surface finish may degrade; small flakes or particulates could be inhaled or ingested, but long-term health impact data for smartwatch materials is absent.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Elastomer band additives (plasticizers, stabilizers, dyes)
Elastomer formulation is not disclosed. Standard rubber bands may contain phthalates or heavy metal pigments, but no testing or complaints are on record for ScanWatch 2 bands specifically.
Stainless steel nickel leaching (rare)
High-grade stainless steel (316L typical in watches) has very low nickel release under normal skin contact; nickel sensitization is a known risk for lower-grade stainless but ScanWatch 2 grade is not specified and no incidents are recorded.
How is this PFAS grade calculated?
The brand's record and disclosure
Withings (owned by Nokia) does not publish materials transparency reports or chemical disclosure statements for wearables. The company has not publicly committed to phasing PFAS or disclosed testing for restricted substances in bands or coatings. This silence on water-repellent coating treatment specifics is common in the smartwatch industry but limits consumer ability to assess waterproofing chemistry. No major product recalls related to material hazards have been documented for the ScanWatch line.
How it compares in its category
Smartwatches generally use similar stainless steel cases and elastomer bands with identical disclosure gaps. The ScanWatch 2 is not differentiated by material safety transparency compared to Apple Watch, Garmin, or Fossil hybrids. Sapphire crystal is actually a premium choice that avoids plastic lens concerns present in lower-cost models. The hybrid design (minimal electronics, mostly mechanical) reduces power consumption and thermal stress on materials versus full smartwatch competitors, slightly lowering chemical leaching risk from heat cycling.
If you buy it
Wash the bands regularly with mild soap and water to minimize skin contact with dyes and finishes; avoid prolonged heat exposure (dishwashers, saunas above 60°C) which can degrade elastomer integrity and increase leaching. Replace elastomer bands every 12-18 months if worn daily, as UV and sweat exposure degrade rubber polymers over time. The stainless steel case and sapphire crystal are durable and pose minimal hazard; focus maintenance on band condition and clasp integrity to maintain water seal. If the band develops visible cracks or discoloration, discontinue use and source replacement bands from Withings or verified third parties rather than unlabeled alternatives.
