The GA-B2100 is the Bluetooth and solar version of Casio's slim 'CasiOak' G-Shock, with analog hands over a digital display. It keeps the octagonal bezel and carbon core guard case that made the line popular, but adds Tough Solar charging and phone-linked timekeeping. It suits people who want a tough everyday watch with a cleaner, less bulky profile than a classic square or Mudmaster. Against the original GA-2100 it fixes the two main complaints, battery changes and no connectivity, while staying lighter and slimmer than most G-Shock analogs.
