Epson · Waterproof Fitness Trackers & Cases
ProSense GPS Multisport Watch
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes stainless steel case, 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 ProSense GPS Multisport Watch is made of, ingredients and materials
The ProSense case is stainless steel, a chemically stable material that does not leach metals or degrade into food or skin contact under normal wear. The elastomer band is a synthetic rubber polymer; elastomers used in sports watches are typically formulated without phthalates in modern designs, though Epson does not publicly detail band composition. Stainless steel and elastomer combination avoids the ceramic glaze, non-stick coating, and plastic-to-water contact pathways that create leaching risk in other product categories.
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 band degradation and microbial colonization
Elastomer bands can accumulate moisture, sweat, and bacteria in seams if not rinsed regularly. No coating or antimicrobial treatment is described, so cleaning is the primary control.
Seal degradation and water ingress
The watch is rated for water resistance, which depends on gasket and seal integrity rather than coating. Seals can degrade over years of use; if water enters the housing, internal corrosion of circuits is possible but does not pose direct chemical hazard to the user.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Phthalates
Modern sports watch bands typically exclude phthalates, but Epson does not publish material safety data sheets for the ProSense band. Industry standard practice suggests low risk, but cannot be confirmed from available sources.
Source, ATSDR ↗Nickel or trace metal leaching from stainless steel
Stainless steel is passivated and extremely stable; nickel leaching risk is negligible under normal skin contact and fresh water use. Prolonged contact with chlorinated pools may increase leaching minimally but remains below concern thresholds for this material.
Formaldehyde / VOCs
Internal electronics and adhesives may contain trace volatile organics, but the sealed housing limits exposure. No off-gassing incidents are documented for Epson fitness watches.

The brand's record and disclosure
Epson, a major consumer electronics manufacturer, maintains ISO 14001 environmental certification and publishes sustainability reports, but does not issue detailed material safety disclosures for wearables. No recalls or contamination incidents are documented for this model. The brand's silence on PFAS is typical for the fitness tracker industry; absence of a public statement does not indicate presence of PFAS, particularly in a metal case design that would not require water-repellent surface coatings.
How it compares in its category
Stainless steel cases present lower concern in waterproof wearables compared to plastic housing with potential leachables and non-stick coating concerns. Most competitors in the multisport GPS segment (Garmin, Suunto) use similar steel or aluminum cases with elastomer bands. The ProSense's material choice is standard and low-risk for the category; differentiation lies in feature set and durability rather than safety profile.
If you buy it
Rinse the band regularly with fresh water after salt water or sweat exposure to prevent elastomer degradation and bacterial growth in crevices. Avoid prolonged exposure to temperatures above 60 degrees Celsius (140 Fahrenheit), as elastomer can soften. Inspect the band for cracking or discoloration annually; replace if visible wear develops. The stainless case requires no special maintenance beyond occasional wiping with a soft cloth.
