The corrosion-resistant titanium buckle and adjustable loop secure the strap during high-speed water sports. For extra length, an extension strap is sold separately — perfect if you need extra length to wear the strap over your wetsuit. Compatible with Apple Watch Models 44mm, 45mm, 46mm, and 49mm. Made from Fluoroelastomer and Titanium. Quantity per pack: 1 pc(s).
