The Ocean band is molded from a high-performance elastomer and is extremely stretchy thanks to its tubular structure. This ensures a perfect fit every time, even over a wetsuit. The corrosion-resistant titanium buckle and adjustable eyelet keep the band securely in place, even during high-speed water sports. For wearing the Ocean band over your wetsuit, the separately available extension is perfect. Included in the box: Apple Watch Ocean band, one adjustable eyelet.
