Amazfit Pace GPS Smartwatch
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes glass/stainless steel case, elastomer strap, 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 strap degradation and bacterial growth
Elastomer straps accumulate sweat and bacteria in porous areas, especially if not cleaned regularly. Degradation itself does not produce toxic byproducts, but compromised straps can irritate sensitive skin. This is a hygiene and durability issue rather than a chemical safety hazard; standard washing prevents it.
Nickel allergy from stainless steel case
Stainless steel contains nickel (typically 8-12%) and can trigger contact dermatitis in nickel-sensitive individuals. Risk is low if the watch does not directly contact skin (worn over clothing), but moderate if worn directly on wrists with broken skin. Amazfit does not specify nickel content or hypoallergenic variants for this model.
Water-resistance seal integrity over time
The 5ATM rating depends on gaskets and adhesive seals that can degrade after 2-3 years or with frequent thermal cycling. If seals fail, water ingress can corrode internal electronics, but this does not create direct chemical hazard to the wearer unless battery leakage occurs (rare in this model). Maintenance and replacement of the device, not material toxicity, is the mitigation.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
The watch glass is not a consumable; no ingestion or skin leaching pathway exists. Modern display glass is not reported to contain lead or cadmium. No hazard identified for this material in this context.
Source, FDA ↗Volatile organic compound (VOC) off-gassing from strap
Elastomer straps do not emit detectable VOCs at body temperature. This is a non-concern for silicone and synthetic rubber elastomers used in fitness trackers. Off-gassing risk applies only to certain plastics and coatings, not to this design.
The full breakdown
What it's made of and why it matters
The Amazfit Pace uses a stainless steel case and glass display paired with an elastomer strap. Stainless steel is a chemically stable alloy that does not leach under normal wear; glass is inert and non-toxic. The elastomer strap is the primary skin-contact material and poses the main assessment point. Elastomers (typically silicone or synthetic rubber in fitness trackers) do not off-gas volatile organic compounds (VOCs) at body temperature, and degradation requires extreme heat or UV exposure not encountered in typical use.
The brand's record and disclosure
Amazfit is a subsidiary of Huami, a consumer electronics company with limited public safety certifications or detailed material disclosures compared to tier-one fitness brands. The brand has not published PFAS statements or comprehensive chemical-safety data sheets for this model. No established recalls or contamination incidents have been reported for the Pace smartwatch. This lack of transparency is typical for budget fitness-tracker brands but does not indicate a known problem.
How it compares in its category
The Pace occupies the budget smartwatch segment where material scrutiny is generally lower than in premium fitness watches. Most competitors in this price range use identical material combinations (stainless/glass case, elastomer strap) without additional coatings or chemical treatments. Higher-end models sometimes add nickel-plated or specialty coatings that introduce trace-element risks; the Pace avoids this by design. Overall material simplicity is a safety advantage relative to more complex watches in the category.
If you buy it
Wash the strap weekly with mild soap to reduce bacterial buildup from sweat, especially if you wear it continuously. Avoid prolonged exposure to high heat (above 60°C/140°F), which can degrade elastomer over time, though this is not a risk during normal wear. Check the strap for visible cracks or hardening after 1-2 years; replace it if damage occurs to maintain water resistance. The watch itself is rated 5ATM (splash/swim-proof), so avoid saltwater immersion; rinse with fresh water after beach use to prevent corrosion at seams.
