The wide face and a high-definition MIP (Memory In Pixel) LCD improves display readability of standard functions like Tide Graph, Moon Data, high tide and low tide times, and sunrise and sunset times. This provides important information about current conditions at a glance, which, in combination with a collection of training measurement functions (distance, speed, pace, lap, pitch), provides plenty of support for surfers who meet new challenges around the globe.
In addition to powerful functions, these new models also incorporate advances in design, structure, and materials. The bezels of these models are made of resin and metal to allow them to withstand the impact of underwater rocks better. The surface of the bezel has a stainless steel cover with a hairline and honed finish that creates a look of elegant toughness. A resin guard structure that protects against impact from any direction combines with a button guard at 6 o’clock, which delivers outstanding G-SHOCK protection.
