Our take on the Casio G-Shock Analog-Digital 2100 Series GA-2100LXB-1A9

The GA-2100LXB-1A9 is Casio's octagonal 2100-series G-Shock, the slim analog-digital model often called the CasiOak. It pairs a carbon and bio-based resin case with Carbon Core Guard construction and a bio-based resin band, so it stays light and thin at 11.8 mm while keeping full shock resistance. Features include world time, a 1/100-second stopwatch, countdown timer, 5 daily alarms, double LED Super Illuminator, hand shift and 200-meter water resistance. It suits people who want a tough everyday watch with analog hands and digital readouts without the bulk of older G-Shocks; rivals like the GA-2100 base models offer the same core package, while this LXB version adds the bio-based materials and a different finish.

About the Casio G-Shock Analog-Digital 2100 Series GA-2100LXB-1A9

The G-SHOCK GA-2100LXB-1A9 is an analog-digital watch with the octagonal 2100 series design. The case is made of carbon and bio-based resin, and the band is bio-based resin. A Carbon Core Guard structure provides shock resistance.

The watch has world time, a 1/100-second stopwatch, a countdown timer and 5 daily alarms. A white double LED Super Illuminator lights the face and the digital display. A hand shift function moves the hands out of the way so the digital display is unobstructed. It is water resistant to 200 meters and runs on two SR726W batteries, with approximately three years of battery life.

Questions and answers

Is the GA-2100LXB-1A9 good for swimming?
Yes. It is rated to 200 meters of water resistance, which covers swimming and snorkeling. Avoid pressing buttons underwater.
How does it compare with the standard GA-2100?
The core module, size and features are the same. This LXB version uses bio-based resin for the case and band and has its own finish, so the choice comes down to looks and materials.
Does it have solar charging or Bluetooth?
No. It runs on a standard battery rated for about three years and has no Bluetooth or solar charging. Those features appear on higher-end G-Shock lines.
How big is it on the wrist?
The case measures 48.5 × 45.4 × 11.8 mm and weighs well under 60 g, so it wears slimmer and lighter than older chunky G-Shocks.
What is in the box?
The watch with its resin band, a user manual and the standard Casio packaging. No charging cable is needed.
Can the hands be moved out of the way of the digital display?
Yes. The hand shift function moves the analog hands aside so you can read the digital subdial clearly.
Where is the Casio G-Shock Analog-Digital 2100 Series GA-2100LXB-1A9 cheapest?
