G-Shock 2100 Series Watch GBX100S-1 | silver/black

from G-Shock's G-Lide line. Inspired by the summer surf scene, the bezel is made with two different materials to evoke the look of shimmering waves gleaming in the sunlight. The bezel top, in stainless steel with mirror-finished beveled edges, contrasts subtly with the glossy translucence of the resin bezel base. All of this delivers the comfortable wearability you're looking for so you can concentrate on riding the waves. Get full functionality at your fingers with Smartphone Link. Just use the dedicated app to select one of some 3,300 major surf spots around the world and send location-specific tide patterns and daylight conditions to the watch. The high-definition MIP LCD also improves visibility and delivers clear tide graph and moon age, as well as high/low tide times and levels, and sunrise/sunset times all at a glance.
