What reviewers say
Casio G-Shock GA-2100 (CasiOak)
Owners widely praise the CasiOak as a tough, good-looking daily watch that punches far above its price. The common complaints are the size on slim wrists and the plastic feel of the case and strap.
- Toughness and shock resistance for the money
- Slim profile compared with other G-Shocks
- Octagonal design that looks more expensive than it is
- Legible analog-digital dial
- Large 45 mm case on smaller wrists
- Resin strap can feel stiff and plasticky
- No solar or Bluetooth on the base model

Questions and answers
- Which is better for everyday wear?
- The GA-2100 suits mixed casual and office wear better because of its analog hands and slimmer look. The GW-M5610 is the easier watch to live with if you never want to set the time or change a battery.
- Is the GW-M5610 worth the extra $54?
- Yes if you value solar power and atomic time sync, which remove battery changes and manual setting. No if you mainly want the look of the GA-2100 and do not mind a battery every few years.
- Which lasts longer?
- Both are shock-resistant resin G-Shocks with 200 m water resistance. The GW-M5610 has an edge on long-term ownership because solar charging avoids repeated battery replacements.
- Which is better for swimming and water sports?
- Both are rated to 200 m, so either handles swimming and snorkeling. Neither is rated for deep diving.
- Which is better for travel across time zones?
- The GW-M5610, with 48 cities and 31 time zones built in. The GA-2100 relies on Bluetooth time-zone changes on connected versions.
- Which fits a smaller wrist?
- The GA-2100 is thinner at 11.8 mm, but its 45 mm case is wide. The GW-M5610 is narrower at 43.2 mm and weighs 52 g, so it usually sits better on small wrists.
