Our take on the Casio G-Shock Analog Digital Red Bio-Based Resin Strap Quartz GA-2100RRB-4A 200M Men's Watch

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.

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.

Questions and answers

Is the GA-2100RRB-4A good for swimming?
Yes. It is rated to 200 meters, which covers swimming and snorkeling. Casio does not rate it for scuba diving.
How does it compare with the standard GA-2100?
It uses the same case, module and 200 m rating. The difference is the red color scheme and the bio-based resin strap and bezel.
Does it have solar power or radio time sync?
No. This model runs on a standard button-cell battery and sets time manually. Solar and radio control appear on higher G-Shock lines.
What is in the box?
The watch with its resin strap, a Casio presentation box and the manual. No extra tools or straps are included.
How does the analog-digital layout work?
Analog hands show the time while the digital window shows date, day and a second time zone. The hands can overlap the digital display at some times.
Is it too big for smaller wrists?
It is one of the slimmer G-Shocks, so it fits most wrists without overhang. The case is still wide, so try it on if you prefer a compact watch.
Where is the Casio G-Shock Analog Digital Red Bio-Based Resin Strap Quartz GA-2100RRB-4A 200M Men's Watch cheapest?
