Some are content to relax and listen to the rhythmic hum of the surf, while others feel the steady thrum like a clarion call, an invitation to become one with the power of nature. The light blue G-SHOCK G-LIDE GLXS5600-2 surf watch is attuned to that clarion call from the design and style to its performance. Smaller and lighter than the GBX-100 series, the GLXS5600 line is designed for those who want a lightweight surf watch with a slim profile to maximize comfort. This digital tide watch is modeled after the very first G-SHOCK by utilizing the popular octagonal bezel still beloved in the modern 5000/5600 series of G-SHOCK watches. Surfing is more than just style, so Casio has stuffed extra surf tech under the hood, helping you to catch the perfect wave in a set.
