Is the GW-M5610 worth it over a basic G-Shock?

Yes if you want solar power and atomic time sync. Cheaper squares like the DW-5600 need battery changes and manual time setting.

How is it different from the GW-M5610U?

The GW-M5610U is the current revision, with an updated module, LED backlight and adjustable date format. Listings for the plain GW-M5610 usually refer to this same square model.

Does it need a battery change?

No routine battery change. The rechargeable cell is charged by light through the dial and typically lasts many years; keep it in light rather than a drawer.

Will atomic timekeeping work where I live?

It works well in the US, UK, Europe, Japan and China near the transmitters. Elsewhere it runs as a normal quartz watch and you set it manually.

Yes. It is rated 200M water resistant, which covers swimming and snorkeling but not scuba diving.
