Our take on the Casio G-Shock (GWG-2000-1A1)

The GWG-2000-1A1 is Casio's smaller, lighter take on the Mudmaster line: a solar-powered analog-digital field watch with a sapphire crystal, a carbon core guard case and a full sensor suite. It packs a compass, barometer, altimeter and thermometer, plus world time, stopwatch, timer and alarms, and it is rated to 200 m. It suits people who want a rugged outdoor tool watch without the bulk of the original Mudmaster. Against rivals like the Garmin Instinct or the full-size GWG-1000, it trades smartwatch features and a bigger case for solar charging, sapphire and G-Shock toughness.

Questions and answers

Is the GWG-2000 smaller than the original Mudmaster?
Yes. It is noticeably smaller and lighter than the GWG-1000, which makes it easier to wear daily. It still keeps the Mudmaster sensor set and 200 m rating.
Does it need a battery change?
No routine battery swaps are needed. A solar cell charges the rechargeable cell from light, and the watch warns you when charge is low.
Can I use it for diving?
It is rated to 200 m and fine for swimming and recreational snorkeling. It is not a dedicated dive computer and has no depth gauge.
Does it have GPS or phone notifications?
No. It has no GPS and no Bluetooth link to a phone. Navigation comes from the compass, barometer and altimeter.
What is in the box?
The watch comes with its resin strap and a manual. No charging cable is needed because it charges from light.
Is the sapphire crystal worth it over mineral glass?
Sapphire is much harder to scratch, which matters on a watch used outdoors. It is one of the main upgrades over cheaper G-Shock models.
Where is the Casio G-Shock (GWG-2000-1A1) cheapest?
