From Freestyle

They're Back. The original Velcro band that ignited Freestyle Watches in the late 80's is back and better than ever. The shark leash's velcro closure system is modeled after an 80's style surfboard leash, and is ready to get radical. The Shark Leash comes loaded with standard digital features like time, date, stopwatch, countdown timer, alarm and night vision backlight. Like all Freestyle Watches, The Shark Leash is water resistant to 100 Meters and backed by our limited lifetime warranty.
