Our take on the G-Shock GA2100-7A7

The Casio G-Shock GA110 is a large-case analog-digital watch with a resin case and band, shock resistance and 200-meter water resistance. Its oversized 55 mm case and bold dial make it a streetwear statement piece rather than a subtle everyday watch. It runs about two years on a CR1220 battery and weighs 72 g despite its size. Compared with slimmer G-Shock models like the GA2100, it is bulkier and more attention-grabbing, which suits people who want a big, tough watch and puts off those with smaller wrists.

Questions and answers

Is the GA110 too big for small wrists?
At 55 mm wide and 16.9 mm thick, it is one of the larger G-Shock cases. The band fits wrists from 145 to 215 mm, but the case will look oversized on slim wrists.
Can you swim with it?
Yes. It is rated for 200-meter water resistance, so swimming and snorkeling are fine. Avoid pressing buttons underwater.
How long does the battery last?
About two years on a CR1220 battery. It is not solar powered, so the battery needs replacing periodically.
How does it compare with the GA2100?
The GA2100 is much slimmer and lighter with a cleaner analog-digital look. The GA110 is bigger, bolder and heavier, aimed at people who want a statement watch.
Does it have Bluetooth or solar charging?
No. The GA110 is a basic battery-powered model without Bluetooth, solar charging or app connectivity.
What is in the box?
The watch with its resin band, a battery already installed and the standard documentation.
