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.

A small French tannery established in 1803 produces the supple Granada leather for this elegant Apple Watch Band. The smooth top-grain leather is lightly milled and tumbled to maintain its refined texture. What looks like a solid buckle is actually a two-piece magnetic closure that’s delightfully simple to secure. Apple also added an inner layer of Vectran weave for strength and stretch resistance. It’s the same material NASA used to make the landing airbags for the Mars rover spacecraft.

Made from a custom high-performance fluoroelastomer, the Sport Band is durable and strong, yet surprisingly soft. The smooth, dense material drapes elegantly across your wrist and feels comfortable next to your skin. An innovative pin-and-tuck closure ensures a clean fit.
