Taking inspiration from retro gaming, the G-Shock x Super Mario Bros. DW5600SMB-4 digital watch has a classic square case design with accents inspired by the Nintendo game. The light blue dial features a green turtle shell, while the durable resin band features an 8-bit Mario design with olive green and red tones. A special edition case back and LED display bring the nostalgic yet playful look together, while a multitude of timing functions and G-shock's legendary toughness make this watch a highly functional piece.
