Casio G-Shock Nano Ring Watch Black/Black (DWN-5600-1ER)

The Casio G-Shock DWN-5600-1ER is a miniature, ring-sized version of the classic G-Shock. Despite its tiny form, it offers shock resistance, 200 m water resistance, and a fully functional digital display with time, calendar, dual time, and stopwatch. LED illumination ensures readability, and its bio-based resin construction keeps it lightweight yet durable — a fun, unique take on G-Shock toughness in a collectible, wearable form.
