The aerospace-grade titanium case strikes the perfect balance of weight, durability, and corrosion resistance.

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 titanium buckle and adjustable loop secure the band during high-speed water sports.
