Realme Watch 5 Smartwatch
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes plastic case, glass screen, 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 Realme Watch 5 Smartwatch is made of, ingredients and materials
The Realme Watch 5 uses a plastic case housing (material type not specified in public data as ABS, polycarbonate, or other resin) and a glass screen. Plastic casings in wearables typically do not pose leaching hazards to skin during normal wear because they are not in prolonged contact with food or beverages and are not exposed to high heat. The glass screen carries negligible chemical risk unless broken, though shards pose a physical hazard rather than a toxicity concern.
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.
Heavy metals
Smartwatch circuit boards, solder, and battery connectors may contain lead or cadmium in trace amounts, as is common in unregulated or lower-cost electronics. However, these are sealed inside the case and pose no risk during normal use unless the device is damaged or dismantled.
Source, FDA ↗Glass screen breakage and sharp edges
Consumer reports indicate that the Watch 5 screen can crack or shatter under impact, creating sharp glass edges that pose a laceration hazard to skin. This is a physical rather than chemical risk.
Battery leakage or thermal runaway
Lithium-ion batteries in smartwatches carry a small but documented risk of leakage or thermal failure if punctured, overcharged, or exposed to extreme temperature. No specific incidents with the Watch 5 have been publicly recorded, but this is an inherent electronics risk.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Plastic off-gassing or leaching from case
No reports of volatile organic compounds (VOCs) or chemical leaching from the Realme Watch 5 plastic case exist in public records. Skin contact during normal wear poses minimal ingestion risk compared to food-contact plastics.
Flame retardants
Realme has not disclosed whether brominated or chlorinated flame retardants are used in the Watch 5's PCB or other internal components. This is standard practice in the industry but remains undisclosed for this model.

The brand's record and disclosure
Realme has not published material safety data sheets or third-party certifications for the Watch 5 that are publicly available. The brand has remained silent on PFAS, flame retardants, or heavy metals in this product line. No recalls related to chemical hazards have been documented for this model. Realme's consumer electronics generally follow basic CE and FCC compliance but do not highlight advanced material transparency.
How it compares in its category
Smartwatches as a category involve minimal material contact compared to cookware or textiles, reducing exposure risk. The Watch 5's plastic-and-glass construction is typical and does not stand out as higher or lower risk than competitors like Xiaomi Mi Band or Apple Watch Series. Most wearables in this price tier do not undergo independent toxicity testing, making direct comparison difficult.
If you buy it
Clean the watch band and case regularly with a soft, damp cloth to remove skin oils and sweat buildup; avoid prolonged contact with harsh soaps or solvents. Do not expose the device to extreme heat (above 50°C) or sustained high humidity, as these may degrade seals and internal components. Replace the watch band if it shows visible wear, cracking, or discoloration, as degraded plastic may shed fine particles. Store in a cool, dry place when not in use.
