Traditionally found in luxury watches, the OnePlus Watch is the world’s first smart watch to utilize cobalt alloy in its middle frame. Twice as hard as stainless steel, it grants a stunning luster and corrosion resistance. It's durable yet irresistible – it’s nickel-free to greatly reduce any skin allergic reactions. Meticulous hand-polishing of the cobalt alloy ensures the elemental elegance resonates.
