Ocean Band Apple, Natural Titanium for Apple Watch, 44/45/46/49 mm, Black

The Ocean Band is molded in a high-performance elastomer with a tubular geometry allowing it to stretch for a perfect fit, even over a wetsuit. The corrosion-resistant titanium buckle and adjustable loop secure the band during high-speed water sports.

For extra length, an extension band is sold separately—perfect if you need extra length to wear the band over your wetsuit.
