Is the GA2100-1A good for everyday wear?

Yes. It is light at 51 g, slim at 11.8 mm and water resistant to 200 m, so it handles daily wear and swimming.

How does it compare with the classic square G-Shock?

It is thinner and lighter than the DW-5600 and adds analog hands, but its digital display is smaller and less legible.

Does it have Bluetooth or solar power?

No. It runs on two SR726W batteries rated for about three years and has no Bluetooth or solar charging.

The watch comes with its original box and papers.

Casio rates it at plus or minus 15 seconds per month.

Can I wear it swimming?

Yes. Its 200 m water resistance covers swimming and snorkeling, though not deep diving.
