Three Apple Watch bands alleged to contain cancer-associated harmful chemicals.
The lawsuit noted that three of Apple’s watch bands, the Sport Band, Ocean Band, and Nike Sport Band, are made with fluoroelastomer. Fluoroelastomer is a synthetic rubber that resists oil and sweat and is made from chains of PFAS, and PFAS is the problem.

A study published in December 2024 found dangerous levels of PFAS on more than a dozen bands of smart or fitness watches, including Apple’s. The same study suggests the increased risk of PFAS absorption through skin during exercise.
According to a report, Cupertino stated that the Apple Watch bands are safe for users to wear. On top of its own testing, the company also works with independent laboratories in rigorous testing and analysis of the materials used in its products.
Apple already pledged in 2022 to remove PFAS from its products, but challenges, particularly finding the best replacement, made the move difficult. Regardless, the lawsuit claims that the company failed to inform its consumers about the potential dangers of such chemicals.
PFAS are found in a wide range of items, from Teflon-coated frying pans to clothing. Its residue is detectable in rainwater and drinking water and is now a major environmental threat because it takes “forever” to break down in nature. It has been associated with some types of cancer as well.
Will you still wear smartwatches after knowing they may contain PFAS?
