G-Shock with GPS: the one model that has it, what Casio's guide says it can do, and what it costs you
Most G-Shocks measure the world; one records it. The Rangeman GPR-H1000 has multi-band GNSS, heart rate and a rechargeable cell, and it trades the months-long battery that defines the brand for days. Here is the honest accounting.

Which G-Shock has GPS
One current model that we rank: the Rangeman GPR-H1000 (module 3554), launched in 2024 per the spec sheet. The GW-9400 Rangeman, the Mudman, the Mudmaster and every square have no GPS; they are ABC watches with a compass, barometer and altimeter. Casio's G-Squad line has fitness GPS models, but they are training watches rather than rugged outdoor ones and we do not cover them. If you searched "G-Shock with GPS and compass" or "G-Shock with GPS and map," the first exists and the second does not: the GPR-H1000 shows position information and a track, not a base map.
Battery: Casio's figures, mode by mode
| Mode (Casio's guide, module 3554) | Operating time |
|---|---|
| Watch mode, heart rate and sleep monitoring on, worn during sleep | About 14 days |
| Watch mode, heart rate and sleep monitoring on, not worn during sleep | About 2 months |
| Watch mode, heart rate only, worn during sleep | About 7 days |
| Watch mode, heart rate only, not worn during sleep | About 10 days |
| Watch mode, heart rate off | About 2 months |
| GPS activity, HIGH GPS setting | About 14 hours |
| GPS activity, NORMAL | About 16 hours |
| GPS activity, LONG | About 19 hours |
| Open water swimming | About 15 hours |
Two months in watch mode with the heart-rate sensor off is a genuinely long figure for a GPS watch; 14 to 19 GPS hours is a day out, not a weekend. Turn the optical heart rate on and wear it to bed and the watch-mode figure drops to a week. This is the trade the whole guide is about.
USB with solar assist is not Tough Solar
Against a Garmin Instinct
The Instinct 3 Solar 50mm is rated 60 GPS hours (260 with solar) and 40 days in smartwatch mode (unlimited with solar) by Garmin's manual, with a 10 ATM rating and a MIL-STD 810 line. The GPR-H1000 is rated 14 to 19 GPS hours and two months in watch mode with heart rate off, at 200 m with mud-resistant construction. The Garmin is the better GPS watch by a wide margin; the Casio is the tougher case with a G-Shock's buttons and seals. For readers who want the case more than the hours, that is a legitimate choice. For everyone else, it is the Instinct, and the wider argument is on G-Shock vs Garmin Instinct.
Who should buy it
A G-Shock owner who wants a track and heart rate for day-long activities and will charge weekly; a hunter who wants a 200 m mud-sealed case with a walk-out track for day trips; anyone who has bounced an Instinct off a rock and wants the deeper bezel. Not a thru-hiker, not a multi-day backcountry hunter, and not anyone who bought a G-Shock to stop charging things.

How we scored this
Watches we claim to have worn or tested: 0
Plenty of sites say they took every watch up a mountain. We didn't, and we say so. What we do instead: read the maker's own battery table mode by mode, check what the lens and case are actually made of, note the water rating and whether a MIL-STD-810 claim exists, ask how long the maker keeps updating the line, and score every pick on a public rubric weighted for a decade of ownership. Every figure links to where it came from.
Scores are editorial judgments from that documented research, not test results. Commissions never set a score or decide a pick. The rubric and its weights are published.
Questions
Frequently asked
Does G-Shock make a watch with GPS?
Yes, the Rangeman GPR-H1000: multi-band GNSS (GPS, QZSS, Galileo, BeiDou, GLONASS on L1/L5), heart rate, 14 to 19 GPS hours per charge, per Casio's module 3554 guide.
Is the GPR-H1000 solar?
Solar-assisted, per the spec sheet: a lithium-ion cell charged by USB with solar helping. It is not Tough Solar and will need the cable.
Does the G-Shock GPR-H1000 have maps?
No. Casio's guide lists GPS position information and activity tracking; there is no topographic base map on the watch.

We don't own or wear-test these watches and we don't pretend to. Battery, glass, case and water figures come from the maker's own owner's manuals, spec pages and press releases (linked on every product), and where a figure isn't published we say so. Prices are set by Amazon and change often, so we don't print them. Read the full method.
