At A Glance
Based on the success of the DW6900CS with its neon highlights on a gloss black case & band, G-Shock brings the same design cues to its Solar Atomic 5600 series of timepieces. Blending technology with fashion, this classic case, is done up in gloss black, contrasted by neon green accents and matching reverse LCD. With its Tough Solar Power & Multi-Band 6 Atomic Timekeeping, this new timepiece fashionably showcases G-Shock’s Self-Adjusting, Self Charging technology.
