Which G-Shock Should You Buy? A Simple Guide to Every Series
Quick picks: for your first G-Shock, get a GA-2100 (slim, light, goes with everything) or a 5600 square (the original, nearly indestructible). Work outdoors? Look at the Rangeman or Mudmaster. Want something you can wear with a shirt? Go Full Metal.
Customers often stand at our G-Shock display looking a bit lost, and we get it. Casio has made hundreds of versions since 1983. The good news is that almost all of them belong to a few families, and once you know those, choosing is easy.
Why G-Shocks are so tough
The first G-Shock came from a simple challenge a Casio engineer set himself: survive a 10-metre drop, resist water to 10 bar, and run 10 years on a battery. The trick is a movement that "floats" inside the case, protected by layers of resin that absorb the shock. Every G-Shock since is built on that idea.
The main G-Shock families
| Family | What it is | Who it suits |
|---|---|---|
| 5600 / DW-5000 | Square digital | The classic. Light, tough, cheap to own. Great everyday or gym watch. |
| GA-2100 | Slim octagon, analog-digital | The modern favourite. Thinner than most G-Shocks and very versatile. |
| GA-100 / GA-700 | Large analog-digital | Big, bold sporty look. |
| Rangeman | Outdoor, with sensors | Compass, altitude, barometer and thermometer. For hiking and hunting. |
| Mudman / Mudmaster | Mud and dust resistant | Buttons sealed against dirt. For job sites and trails. |
| Full Metal (GMW-B5000) | Steel or titanium square | The 5600 shape in metal. Dresses up nicely. |
| MR-G | Top of the range | Premium titanium models made in Japan. |
Solar, radio and Bluetooth: what the extras mean
- Tough Solar: light charges the battery. Wear it normally and you'll rarely, if ever, change a battery.
- Radio-controlled (Multi-Band 6): the watch picks up time signals and sets itself overnight. Reception in Canada depends on where you live, so it works best in the south of the country.
- Bluetooth: the watch syncs the time with your phone and handles time zones automatically. Useful if you travel.
If you can, get solar. It's the feature you'll appreciate most a few years from now.

Common questions
Are G-Shocks waterproof?
Most are water resistant to 200m, which covers swimming and snorkelling. Don't press buttons under water unless the model says it's safe.
How long does a G-Shock last?
With basic care, many last decades. Resin straps and bezels wear over time but can be replaced.
Is the GA-2100 really a "CasiOak"?
That's the nickname fans gave it because the octagon shape recalls a famous luxury watch. It's a G-Shock through and through, at a fraction of the price.
