Kanoa Igarashi's fourth G-SHOCK signature model takes its brown mixed-resin bezel and band from the cliffs of Portugal, one of his home surfing locations. Lavender vapor deposition on part of the glass adds his favorite color. A tide graph, heart-rate measurement, training analysis and high-definition MIP display support both ocean activities and everyday workouts. A carbon-reinforced resin case back makes it approximately 12 g lighter than the heart-rate-equipped DW-H5600. His signature and competition number 50 appear in the design. Mixed-resin colors and patterns vary between individual watches. Major resin components in the case, bezel and band use bio-based resin.
