The Brig by Jordy Smith is a digital tide & train watch that can track the tide at over 200 beaches worldwide for the next 20 years. It also offers a host of other high end features like a digital tide graph that features current tide height, quick access to Vestal's own custom training mode with "Suffer and Recover" interval timer, and Heat Mode with countdown timer so you can practice your surf heats like Jordy. The watch strap is secured to your wrist with a new patent pending OKTOLOCK system. The OKTOGRIP raised pattern on the underside of the band means significantly less rubber contact against your skin providing greater breathability, more flexibility, and a lighter feel on your wrist.
