Garmin watches do not contain nickel. The material used in constructing Garmin watches is 316L surgical-grade stainless steel. This material has a low reactivity level and will not cause an allergic reaction. If you are concerned about nickel, you can purchase a watch with a band made of titanium or rubber instead of stainless steel. These materials are hypoallergenic and safe for everyone. Nickel can be found in many different types of jewelry, including rings and earrings. Nickel skin irritation may be caused by exposure to nickel in these products, especially if they come into contact with the skin regularly.
