Our take on the Casio G-Shock (GW9400-1B)

The GW9400-1B is the Rangeman, G-Shock's triple-sensor survival watch. It packs a barometric altimeter, thermometer and digital compass alongside solar charging and Multi-Band 6 radio timekeeping, so it never needs a battery change or manual time setting. Build is resin case and strap with mineral glass and 200m water resistance. Compared with a basic G-Shock it is bulkier and busier, but no rival at this level combines three sensors with solar and atomic sync. It suits hikers, climbers and outdoor workers more than desk wearers.

Questions and answers

Does the GW9400-1B need a battery change?
No. It charges from light through a solar cell, so there is no user-replaceable battery to swap.
How accurate is the altimeter?
It reads altitude from barometric pressure, so it needs calibration at a known height and drifts when weather changes.
Can I swim with it?
Yes. It is rated 200m water resistant, which covers swimming and snorkeling, but not scuba diving.
Does it set itself automatically?
Yes, where a radio signal is available. Multi-Band 6 syncs time from atomic transmitters; elsewhere you set it manually.
How does it compare with a basic G-Shock?
It adds three sensors, solar charging and radio sync. That makes it bigger, heavier and more complex than a plain digital G-Shock.
Is the display easy to read?
The negative LCD is legible in bright light but dimmer than a standard positive display in shade or at night.
Where is the Casio G-Shock (GW9400-1B) cheapest?
At Newegg, for $330.00, as of our latest check.
