Is the Rangeman GW9400-1 good for hiking?

Yes. The altimeter, barometer, compass and thermometer give useful trail information, and the shock-resistant 200 m case handles rough use.

Does it need a battery change?

It runs on a rechargeable cell charged by light, with about 8 months of runtime on a full charge without further light exposure. Radio sync handles the time.

How does it compare with other G-Shocks?

It adds a triple sensor and solar radio timekeeping that basic models lack, at the cost of a larger, heavier case.

Will it fit a small wrist?

It is a large watch at 55.2 by 53.5 mm and 18.2 mm thick. Shoppers with slim wrists often find it oversized.

Is it waterproof for swimming?

It is rated to 20 ATM, or 200 meters, so it is fine for swimming and snorkeling but not for scuba diving.

The watch on its resin band, along with the usual documentation. It arrives charged enough to run and tops up in light.

Our take on the Casio Rangeman GW9400-1 AS MB6 Twin Sensor Wristwatch

The Casio Rangeman GW9400-1 is a Master of G G-Shock built for outdoor use. It pairs a digital display with a triple sensor set: altimeter, barometer and compass, plus a thermometer. Solar charging and Multi-Band 6 radio timekeeping mean it rarely needs a battery change or manual setting. It is bulky at 55.2 by 53.5 by 18.2 mm and heavy on the wrist, so it suits hikers, climbers and field workers more than people wanting a slim everyday watch. Against simpler G-Shocks it adds real navigation tools; against a smartwatch it trades apps and a screen for toughness and months of runtime. Owners rate it highly for durability and sensor usefulness.
