A:Answer Hello Angie, thanks for taking the time to ask us your question about the Samsung Galaxy Watch8. The Galaxy Watch8 is made with Armor Aluminum + Sapphire Crystal. Galaxy smart watches do not contain internationally restricted materials or any harmful materials that directly come into contact with the skin. We also verified compliance with international environmental regulations through authorized international test institutions for certain materials, such as the fiber, leather, plastic, and metal, which have a high possibility of contacting the skin. When using materials not explicitly covered by international standards, we conduct our own internal wearing tests, noxious material tests, and skin toxicity tests for all materials that come into contact with skin in cooperation with domestic and external certificate authorities. Please feel free to review, "Properly wear and clean your Samsung smart watch" if you would like to learn more. Feel free to reach out to Support afterward if you have any questions or if you would like any further assistance. Thank you for being a valued Samsung customer. - Debra
