The Casio G Shock Digital DWN-5600-4JR is a groundbreaking "G-SHOCK Nano" timepiece that reimagines the iconic DW-5600 in a fully functional Ring Watch format. Roughly 1/10th the size of the original, this miniature marvel features the classic Red colorway, a fan-favorite hue from G-SHOCK history, making it an instantly recognizable statement piece. Despite its tiny proportions (23.4mm x 20mm x 7.5mm), this is a genuine G-SHOCK. It is built with a shock-resistant structure and boasts an incredible 200-meter (20 Bar) water resistance rating, ensuring it can withstand water immersion just like its full-sized counterparts. The Bio-based Resin case and strap are crafted with advanced molding technology to precisely replicate the intricate details of the original bezel and band. Powered by a replaceable battery (approx. 2-year life), the watch features a clear 6-digit LCD displaying 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 with a display stand.
