Suunto Ambit 1 Smart Watch Band with Removal Tool
Lower concern, but Suunto doesn't confirm PFAS status.
This elastomer or silicone replacement band is inherently lower PFAS risk. Suunto makes no PFAS claims or disclosures.

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.
Skin irritation or allergic reaction from additives
Silicone may contain trace accelerators, colorants, or mold-release agents that rarely trigger contact dermatitis in sensitive users; no cases specific to Ambit 1 band are documented, but pre-wear testing on inner wrist is prudent.
Heavy metals
Pigments in colored silicone bands may theoretically contain trace lead or cadmium, but no recalls or safety alerts exist for Suunto bands; regulatory risk is low under EU and US standards.
Source, FDA ↗What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Teflon-type coating/non-stick coatings absent
Silicone watch bands do not use Teflon-type coating or Teflon-family coating coatings, so there is no risk of thermal decomposition fumes.
BPA & bisphenols
High-grade silicone does not use phthalates or BPA; risk is negligible unless the band is degraded or counterfeit.
Source, FDA ↗Microplastic shedding under wear or heat
Silicone bands do not degrade into microparticles under typical body temperature or sweat exposure; risk is minimal over the product lifespan.
The full breakdown
What it's made of and why it matters
The Ambit 1 band is constructed from elastomer or silicone rubber, a synthetic polymer chosen for durability, water resistance, and comfort against skin. Silicone is chemically inert at typical wear temperatures (below 60C body contact) and does not leach plasticizers like BPA or phthalates under normal use. The material is stable and does not degrade into microparticles through routine wearing, making it low-risk for ingestion or systemic absorption compared to lower-grade rubbers or PVC alternatives.
The brand's record and disclosure
Suunto, owned by Amer Sports, does not publicly disclose PFAS content or chemical safety protocols for wearable bands, which is common across sports-watch manufacturers. The brand has no known product recalls for chemical contamination of watch bands or accessories. Suunto maintains ISO 9001 manufacturing standards but does not offer third-party material certification (e.g., SGS, CPSC testing reports) for this specific product on retail or support channels.
How it compares in its category
Silicone watch bands show lower concern for skin contact compared to PVC, butadiene rubber, or polyurethane blends, which may off-gas volatile compounds or contain legacy flame retardants. Most mainstream sports-watch brands (Garmin, Apple, Fitbit) use similar silicone formulations with equivalent transparency gaps on PFAS and additives. The inclusion of a removal tool is standard and adds no chemical risk; it is a stainless-steel or plastic utility item.
If you buy it
Rinse the band after saltwater or chlorinated pool exposure to prevent salt accumulation and dermatitis, but do not soak in harsh detergents or expose to direct heat above 70C. Replace the band if visible cracks, permanent discoloration, or tackiness develops, as these signs indicate polymer breakdown. Store the band away from direct sunlight and volatile solvents (acetone, gasoline) to preserve elasticity. The removal tool should be kept dry to prevent rust if metal-based.
