The Casio G Shock Digital DWN-5600-9JR is a groundbreaking "G-SHOCK Nano" timepiece that transforms the legendary toughness of the DW-5600 into a fully functional Ring Watch. This model features the vibrant Yellow colorway, a fan-favorite hue that pays homage to classic limited editions, making it an instantly recognizable and playful accessory. Shrunk to approximately 1/10th the size of the original wrist model, this miniature marvel does not compromise on performance. It is built with a shock-resistant structure and boasts an impressive 200-meter (20 Bar) water resistance rating, ensuring it is as durable as it is unique. The case and strap are crafted from eco-friendly Bio-based Resin, utilizing precision molding to replicate the intricate details of the full-sized watch. Powered by a replaceable battery (approx. 2-year life), the ring features a clear 6-digit LCD that displays hours, minutes, and seconds. Practical functions include Dual Time, a 1/100-second stopwatch, auto-calendar, and a unique Flashing Light that pulses at a preset time. The adjustable strap fits finger circumferences from 48mm to 82mm, and the watch comes in special collector's packaging, making it the ultimate conversation piece for G-SHOCK fans.
