Features

These GW-B5600 Connected Engine models feature the distinctive square design of the 5000/5600 Series, which still maintains the same basic form as the original DW-5000C.
Function-wise, these models are designed for outstanding timekeeping accuracy using Bluetooth data communication and Multi Band 6, which supports automatic time setting adjustment based on one of six time calibration signals around the globe. Time information also can be acquired from an internet time server using the G-SHOCK Connected*1 app running on a smartphone.
Other functions include Tough Solar in combination with CASIO original power saving technology that delivers a stable supply of power, high-brightness Full Auto LED illumination, World Time, and more. A selection of six languages for the day of the week indicator*2 provides localization at the press of a button.
Use of an advanced engine makes it possible to achieve high-density component mounting without affecting the size of the finished timepiece. This and much more creates a modern timepiece that delivers the perfect blend of looks and performance.
