Samsung Galaxy Watch Ultra (2025) Titanium LTE 64 GB Display
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes titanium case, AMOLED display, 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 Samsung Galaxy Watch Ultra (2025) is made of, ingredients and materials
The Galaxy Watch Ultra uses a Grade 5 titanium case, which is biocompatible, corrosion-resistant, and does not leach metals under normal wear conditions. The AMOLED display is sealed behind glass with no known use of toxic adhesives or binders in the public record. Titanium's inert nature means no aluminum leaching, no lead in case glazing (not applicable here), and no ceramic coating degradation risks that affect enameled cookware or lower-cost watches.
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.
Seal degradation and water ingress
The 100 m water resistance rating depends on gasket integrity. Over years of use or after impact, seals may fail silently, allowing moisture ingress that can corrode internal electronics but not directly expose the user to chemical hazards.
Band material allergens (dependent on strap type)
The base unit is titanium, but interchangeable bands may include rubber, silicone, or leather. Rubber and synthetic bands can contain accelerators or preservatives that trigger contact dermatitis in sensitive users; Samsung's band materials are not always fully disclosed.
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 lead or cadmium in display assembly has been reported for Samsung smartwatches. Internal solder likely meets RoHS limits, but full component transparency is not publicly available.
Source, FDA ↗Glass and internal component breakage risk
The AMOLED display is covered by hardened glass; breakage risk is mechanical rather than chemical. No toxicity hazard is associated with the glass itself under normal use.
Formaldehyde / VOCs
PCB materials in sealed devices are not a user exposure route. No formaldehyde off-gassing or flame retardant leaching into skin contact zones has been documented for Samsung wearables.

The brand's record and disclosure
Samsung has published sustainability reports disclosing manufacturing processes and has faced no major recalls for material toxicity in wearables. The brand does not make explicit PFAS avoidance claims for the Watch Ultra, and no coating or water-resistance layer on this model is documented as PFAS-treated. Samsung's general approach to materials disclosure is above industry baseline, though device-specific teardown data remains limited in the public domain.
How it compares in its category
Most premium smartwatches use stainless steel or aluminum; titanium is rarer and more stable. Unlike polymer or rubber watch bands (which can off-gas), the titanium case itself poses minimal VOC or plasticizer risk. Entry-level competitor watches often use unclear metal alloys or coated cases; this product's sealed construction and documented material are more transparent than typical mid-market alternatives.
If you buy it
Avoid prolonged contact with harsh chemicals or saltwater immersion beyond the rated 100 m IP rating to prevent seal degradation. Clean the case and band regularly with mild soap and water to prevent skin irritation from sweat accumulation, not from the titanium itself. The watch is designed as a sealed unit; do not attempt to open or service it at home. Replace the band if it shows cracks or discoloration to prevent contact dermatitis.
