TomTom Multi-Sport GPS Watch
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes plastic/elastomer case, 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 TomTom Multi-Sport GPS Watch is made of, ingredients and materials
The TomTom Multi-Sport GPS Watch uses a plastic or elastomer case and band construction typical of sports watches. These materials are chosen for durability, flexibility, and water resistance through their inherent molecular structure and sealed design rather than applied chemical coatings. Elastomer (rubber-like polymers) and engineering plastics are generally stable at skin temperature and during normal wear, with no known leaching of hazardous monomers under typical use conditions.
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/plastic degradation over time
Prolonged UV exposure and thermal cycling during outdoor use can cause elastomer bands to become brittle or tacky; this is cosmetic and safety-related only if cracks allow water ingress into electronics.
Seal integrity failure
Waterproof rating (typically IP67 or 5ATM for this class) depends on gaskets and assembly quality, not chemical coatings. Drops or manufacturing defects could compromise seals, allowing moisture into the electronics compartment.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
No recalls or public reports of lead, cadmium, or mercury in TomTom Multi-Sport GPS Watch circuitry or casing. Electronics-grade plastics and solder comply with RoHS directives in most markets.
Source, FDA ↗Volatile organic compounds (VOCs) off-gassing
New watches may emit trace VOCs from adhesives or molding compounds for the first few hours of use; this is typical, transient, and not a documented safety issue for this product.
Formaldehyde / VOCs
No public testing or hazard reports exist for this specific model. Injection-molded plastic and elastomer bands are unlikely to contain these additives, but brand does not publish material specifications or safety certifications.

The brand's record and disclosure
TomTom is a GPS and navigation technology company with no established pattern of chemical safety disclosures for wearables. No public statements, certifications (such as OEKO-TEX or similar textile safety marks), or recalls related to chemical hazards in this watch model are on record. The brand has not published PFAS use or avoidance statements for this product line.
How it compares in its category
Sports watches in this segment typically avoid problematic coatings because waterproofing is achieved through case sealing, gaskets, and material selection rather than surface treatments. The TomTom Multi-Sport GPS Watch follows this standard approach. Compared to lower-cost fitness trackers, sealed sports watches generally present fewer surface chemical exposure pathways because they minimize exterior additives or finishes.
If you buy it
Rinse with fresh water after salt water or heavy sweat exposure to prevent salt corrosion of seams and electronics. Avoid prolonged exposure to extreme heat (above 60°C/140°F) which could stress elastomer seals. If the case shows visible cracks, separation, or water ingress, discontinue use to prevent internal corrosion. Replace the band if it becomes sticky, discolored, or embrittled, as these may indicate elastomer degradation.
