Here's a brand new Casio model to help surfers navigate through the gnarliest of waves. The display of the G-Shock G-Lide GWX-8900B-7DR not only includes a tide/moon graph display but also measures tidal movements for the top 100 surf locations around the world, with an additional 49 unused slots available for the user to affix their favorite destinations. Other features include shockproof and 200m water-resistant casing, solar-powered battery, full auto super Illuminator LED, and the usual G-Shock workings. Available in all black or black and white colorways, the G-Lide will be released at select stockists starting from August 2012.
