The Casio G-Shock GA-2100RRB-4A is a slim analog-digital G-Shock in the octagonal 'CasiOak' case shape, built with a bio-based resin strap and bezel. It runs on quartz, is water resistant to 200 meters, and pairs analog hands with a small digital window for date, day and a second time zone. It suits people who want a tough everyday watch with a streetwear look rather than a dress watch. Against other G-Shocks it is noticeably thinner and lighter than the chunky 5600 and Mudmaster lines, though it gives up some of their rugged extras. Against fashion watches in the same style it keeps full G-Shock shock resistance and 200 m water resistance.

Owners of the GA-2100 line praise the slim case, light weight and the octagonal look that reads as a more affordable take on a luxury sports watch. Most find it comfortable for daily wear and trust the 200 m rating. Common complaints are the small, dim digital display and the plastic feel of the strap and bezel.
