Black Tomtom Water Resistant Watch Model 8rs00 With Wristband
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes plastic/elastomer wristband, exact, 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 off-gassing
Plastic and elastomer wristbands can degrade in UV light or with prolonged heat exposure, potentially releasing volatile organic compounds. No specific complaints on record for TomTom 8rs00, but this is a known lifecycle risk for polymer wristbands, especially in hot climates or with storage near heat sources.
Bacterial growth in seals and crevices
Any sealed waterproof device creates dead zones where moisture and sweat accumulate if not regularly cleaned. The TomTom 8rs00's gaskets and case joints are not described in publicly available detail, but standard fitness tracker design allows biofilm formation if left wet or unwashed.
Contact dermatitis from additives or microbial buildup
Elastomer wristbands may contain accelerators, antioxidants, or dyes that trigger skin sensitivity in susceptible individuals. Infrequent cleaning and prolonged moisture retention increase risk of secondary fungal or bacterial irritation. No TomTom-specific complaint pattern identified, but this is common across the category.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Phthalates
Modern elastomer wristbands for consumer electronics sold in the EU typically avoid phthalates due to RoHS and REACH compliance. No recalls or test results naming phthalates in TomTom fitness trackers are public; the risk is low but not ruled out by brand disclosure.
Source, ATSDR ↗Heavy metals
Black elastomer typically uses carbon black or organic dyes, both of which pose minimal heavy metal risk in EU-compliant products. No cadmium, lead, or antimony contamination has been reported in TomTom wristbands; EU toy and electronics regulations restrict these in consumer contact materials.

What it's made of and why it matters
The TomTom 8rs00 wristband is plastic or elastomer (rubber-like polymer), which is chemically stable and does not require protective surface coatings to achieve water resistance. The waterproof rating comes from sealed mechanical construction (gaskets, housing design) rather than fluorinated or Teflon-type coating coatings. Plastic and elastomer wristbands do not leach aluminum, lead, or cadmium as ceramic or enameled cookware does, making them a lower-risk material class for skin contact.
The brand's record and disclosure
TomTom is a consumer electronics and GPS company with no widely documented safety recalls or chemical disclosure controversies specific to wristband materials. The brand has not published a public PFAS or hazardous substance policy; however, the absence of a coating description on this model reduces suspicion of intentional fluorochemical application. TomTom products generally comply with EU CE marking and RoHS directives, which restrict certain heavy metals and phthalates in consumer electronics.
How it compares in its category
Fitness trackers and smartwatches with plastic or elastomer wristbands are the norm and carry lower chemical hazard profiles than those with metal or coated surfaces. Most competitors (Garmin, Fitbit, Apple Watch Sport bands) use similar elastomer materials. The TomTom 8rs00 does not stand out as unusually risky or unusually well-disclosed compared to peers; it sits in the mainstream safety middle of this category.
If you buy it
Rinse the wristband with fresh water after saltwater or chlorine exposure to prevent salt or chemical buildup and elastomer degradation. Avoid prolonged direct sunlight when not wearing, as UV can degrade polymers over time. If the band becomes sticky, cracked, or discolored after 1-2 years of use, replace it (most fitness tracker bands are modular and affordable). Periodically wipe the band and watch contact points with a damp cloth to remove sweat and skin oils that can harbor bacteria in crevices.
