Garmin Lily 2 Smartwatch
Consumer smartwatch with unspecified waterproofing; limited PFAS data available.
Garmin does not disclose PFAS use in Lily 2. Waterproofing and elastomer seals raise typical concerns, but no confirmed PFAS detection or independent testing exists.

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/silicone band degradation and bacterial colonization
Composite bands can develop microfissures and trap bacteria if not cleaned regularly, particularly in crevices; degradation is cosmetic and hygienic rather than chemical, but worn bands should be replaced.
Waterproof elastomer seals (unidentified Teflon-family coating composition)
Seals likely contain Teflon-family coating-based compounds to achieve waterproofing; Garmin does not disclose whether Teflon-type coating, PFOA-legacy, or PFAS-free alternatives are used, limiting risk assessment.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Nickel leaching from stainless steel case
Stainless steel 316L (typical for sports watches) sheds negligible nickel under normal skin contact; no case or regulatory findings document sensitization from Garmin smartwatches.
Battery or internal component leakage
Sealed lithium-ion batteries and circuit boards pose no direct contact risk if the case remains intact; no documented leaks or corrosion incidents in the Lily line are on record.
Off-gassing from adhesives or resin in composite construction
Smartwatch components are assembled with minimal organic solvent adhesives; no odor, respiratory irritation, or VOC reports exist for Garmin wearables, and external wear limits inhalation exposure.
The full breakdown
What it's made of and why it matters
The Garmin Lily 2 uses a stainless steel case, which is chemically stable and does not leach metals under normal wear conditions. The composite band (elastomer/silicone blend typical of sports watches) does not contain phthalates or BPA based on Garmin's standard material specifications, though formal certification is not published. Waterproof seals use elastomer compounds; the specific Teflon-family coating type (and thus PFAS content) is not disclosed by Garmin, which is common industry practice for smartwatches.
The brand's record and disclosure
Garmin does not publish detailed material safety disclosures, chemical certifications, or PFAS statements for consumer wearables, which is standard for the smartwatch sector but limits transparency. The company has no documented recalls tied to chemical leaching or coating degradation for the Lily line. No independent testing or regulatory findings of hazardous substances in Garmin smartwatches are on public record.
How it compares in its category
Smartwatches as a category present minimal chemical exposure compared to cookware or cosmetics because contact is external, intermittent, and non-ingestion. The Lily 2's materials are representative of mid-range sports watches; competitor models (Fitbit, Apple Watch, Polar) use comparable stainless steel cases and silicone bands with equally sparse disclosure. Metal and elastomer composition poses lower risk than ceramic-coated cookware or plastic food storage containers.
If you buy it
Rinse the band regularly with fresh water after sweat or salt-water exposure to prevent accumulation of corrosive residues and maintain elastomer flexibility. Avoid prolonged exposure to temperatures above 60°C (140°F), which can degrade elastomer seals and trigger minor off-gassing; normal wear poses no risk. Replace the band if visible cracking, discoloration, or stiffness develops, as degraded elastomer may harbor bacteria. Clean the stainless steel case with a soft cloth; avoid abrasive cleaners that scratch the finish.
