Samsung · Waterproof Fitness Trackers & Cases
Samsung Galaxy Watch3
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes stainless steel case, various polymers, possibly water-repellent, 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.
Nickel leaching from stainless steel
Stainless steel can release trace nickel under acidic or sweaty conditions. Risk is low for this sealed wearable with brief skin contact, but individuals with nickel sensitivity may develop localized irritation after hours of wear. Band removal and washing regularly will minimize accumulation.
Elastomer band degradation and skin contact
Over 1-2 years, silicone or fluoroelastomer bands may degrade from UV and sweat exposure, potentially releasing oligomers or residual catalysts. No contamination has been reported for Galaxy Watch3 bands, but end-of-life replacement is prudent if discoloration or stiffening occurs.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Battery leakage if seal breached
The sealed lithium battery poses no hazard under normal use. If the case is damaged and water ingresses, internal corrosion could occur, but lithium batteries are not designed to be user-replaceable and breach is rare in unmodified units.
Off-gassing from internal polymers
Internal circuitry and insulation are sealed from air and skin contact. Off-gassing is not a hazard for intact watches; no volatile organic compounds from the device have been documented in wearable conditions.
Water-repellent coating or treatment on band/case
Samsung has not disclosed any fluorinated water-repellent surface treatment on the Galaxy Watch3. Water resistance derives from sealed construction and metal/elastomer material properties, not applied coatings; PFAS hazard from surface treatment is not present based on available information.
The full breakdown
What it's made of and why it matters
The Galaxy Watch3 uses a stainless steel case exterior, which is corrosion-resistant and does not leach metals under normal wear. The band is typically elastomer (silicone or fluoroelastomer), and the display is protected by Gorilla Glass. The internal circuitry and battery are sealed from skin and food contact. Stainless steel and elastomer do not present acute leaching hazards in wearable applications where contact is brief and dry most of the time.
The brand's record and disclosure
Samsung has not made public statements specifically addressing PFAS in wearables, nor has it published material safety data sheets for the Galaxy Watch3. The company does maintain general sustainability commitments but does not certify this product against independent material standards. No recalls or disclosed contamination events have been reported for this model related to toxic leaching or coating degradation.
How it compares in its category
The Galaxy Watch3 sits in the mid-to-premium fitness tracker segment with sealed construction similar to Apple Watch and Garmin. Stainless steel cases have lower concern than plastic-only housings because they resist off-gassing and do not require chemical coatings for water resistance. Most competitors in this price and feature class use similar material strategies, sealed metal or reinforced polymer with no disclosed fluorinated water repellents on the band or case.
If you buy it
Rinse the band and case after sweating or salt water exposure to prevent salt-induced corrosion and skin irritation from trapped minerals. Do not submerge the charging port or attempt to disassemble; water ingress can degrade internal seals and expose electronics. Replace the band if it shows cracking or discoloration, as elastomer degradation may increase irritant contact. Store away from extreme heat (above 50C sustained); this does not affect the metal case but can stress polymer components and battery longevity.
