The Brig is a digital tide & train watch that can track the tide at over 200 beaches worldwide for the next 20 years. Design in collaboration with World Professional Surfers Jordy Smith and CJ Hobgood, the Brig 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 a countdown timer while in surf competitions. The watch strap is secured to your wrist with a 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.SPECIFICATIONS CASE: 44mm Wide Polyurethane Wrapped Abs Plastic BAND: 24mm Wide PolyurethaneBUCKLE: Screw-Down Stainless SteelCRYSTAL: Japanese Hardened AcrylicMOVEMENT: Custom Digital Tide/TrainWATER RESISTANCE: 10 ATM / Surfing, Swimming & SnorkelingWRIST: Medium BRIG INSTRUCTIONS
