Is the GA-2110SU the same as the GA-2100?

It is the same CasiOak platform with a different color scheme. The case, module and features are shared with the GA-2100 line.

Yes. It is rated 200m water resistant, so swimming and snorkeling are fine. Avoid pressing buttons underwater and skip deep diving.

Does it have a light?

Yes. It has a double LED light that illuminates the hands and the digital display.

The analog hands are clear, but the negative LCD subdial is dim in low light. Many owners rely on the backlight for the digital readout.

It uses a CR2016 cell, quoted at about three years. It is not solar, so the battery needs replacing eventually.

No. It is a standalone quartz watch with no Bluetooth or app connectivity; those features start on higher G-Shock models.
