ProSense GPS Running Watch
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes plastic housing, elastomer band, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

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.
Elastomer degradation and sweat bacterial colonization
Elastomer bands can trap sweat and bacteria if not cleaned regularly, though the material itself is not toxic. Risk is hygiene-related, not chemical leaching.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Plastic housing brittleness and microplastic shedding
No recalls or reports of crack-induced microplastic shedding from this model. Impact damage could theoretically produce small fragments, but this is not a documented hazard for this product.
Nickel or metal allergen contact
No metal hardware or plating is described for this model; pure plastic and elastomer should not trigger nickel contact dermatitis in typical wearers.
Formaldehyde / VOCs
No formaldehyde-releasing or brominated flame retardant treatments are documented for Epson fitness tracker housings. Standard consumer ABS or polycarbonate may contain minimal residual formaldehyde, but not at levels of concern for brief skin contact.
Source, ATSDR ↗BPA & bisphenols
No water contact leaching of BPA/BPS is expected from a sealed plastic watch case during normal wear or rinsing. Internal electronic components are not user-exposed.

What it's made of and why it matters
The ProSense GPS Running Watch uses plastic housing and elastomer (rubber-like polymer) for the band. Plastic housings in fitness trackers are typically polycarbonate or ABS, neither of which leaches significantly during normal wear or brief water exposure. Elastomer bands avoid the phthalate concerns of softer PVC, though quality varies by manufacturer. Epson does not publicly disclose the specific plastic resin or elastomer formulation for this model.
The brand's record and disclosure
Epson is a major electronics manufacturer with established quality control but does not publish detailed material safety or chemical disclosure statements for wearables. No significant recalls or hazard reports are on record for this specific model or Epson's fitness tracker line. The brand has not made a public PFAS stance for consumer products, and no coating or treatment is documented that would introduce PFAS.
How it compares in its category
Most fitness trackers in this price and function range use similar plastic and elastomer construction. Compared to metal-cased alternatives (which may have nickel or other allergen risks), plastic housings pose lower contact dermatitis risk. Compared to silicone bands (premium but less durable), elastomer bands offer adequate comfort for typical daily and exercise wear, though elastomer can degrade faster under UV and sweat over years of use.
If you buy it
Rinse the band regularly with fresh water after sweaty activity or chlorinated water exposure to prevent material degradation and bacterial buildup. Avoid prolonged direct sunlight storage, as elastomer can harden and crack over time. Replace the band if it shows tears, discoloration, or visible wear; the housing should remain serviceable for several years. Do not expose to extreme heat (above 60°C/140°F) as plastic can warp and elastomer can degrade.
