Sport, GPS, cardio and autonomy: sufficient to progress
G-Shock Move app: sync & limits
Dedicated app G-Shock Move : Strava, Apple Health and Google Fit synchronization, essential settings, logical widgets (MODE to scroll, DISP to change the view). Basic training plans, interval programming by timers (simple, effective… but limited).
No advanced export of sessions from the app, and detailed history especially on the smartphone side. For serious monitoring: rename each activity, note conditions and D+ just after the exit (stupid method but it works).
App tested and synchronized on 10/13/2025 after the release of Pic Carlit; Strava/Apple Health check OK.
Sensors and precision
On-board sensors: optical cardio on the wrist, GNSS (GPS/GLONASS/QZSS), altimeter-barometer, compass, thermometer, accelerometer. On the Carlit (loop 15 km / +952 m), the recorded track showed 15.4 km at the stop sign, i.e. ~2.7% difference compared to the official distance on the sign. The D+ stood at +930 m on the watch, compared to +952 m announced and ~+960 m on my smartphone log. Nothing absurd. Typical of a rocky terrain, numerous bends and micro-gusts of wind. OK to follow a training plan without obsessing.
Cardio side, average 148 bpm vs 150 bpm on reference belt, peaks a little smoothed out when the sleeve was damp. Nothing new: the optics remain dependent on skin contact. Zone alerts (vibration) are useful when climbing; we put in the effort without scrutinizing the screen. The calculated VO2max remains indicative, but consistent with my usual values (38–42). Classic, but reliable.
Profiles, data, simplicity
We personalize the screens, we choose our fields, we launch. No obscure submenus, no sanctimonious assistants. And frankly, enough is enough. The watch lets you run. I prefer that to nit-picking recommendations. So, we focus on the gesture, not on the technology.
Autonomy and energy
Two circuits: solar assisted for daily life (time, steps, notifications), USB for sustained training. Casio announces a big day of effort without cable: confirmed on 10/13/2025 with 4:52 hours of recording (normal GPS + HR) for a battery drop of around 27% from 100%. Full recharge observed at ~2:35 a.m. on computer USB-A port. In short: we leave confident, we return confident. And we are not desperately looking for a catch at the shelter.
Need to situate this autonomy and this positioning compared to the brand’s other references? The best G-Shock panorama for all budgets to discover puts things in their place very quickly.
Quantified differences (distance, D+, FC) from the test log of 10/13/2025; autonomy and recharge timed on the same day; manufacturer specifications consulted to frame the orders of magnitude.
For whom, purchasing experience and summary
For whom it is relevant
Yes if you are looking for a puncture-proof sports watch for hiking, trail running, nature running, indoor running. Readable everywhere, autonomous, simple. Yes if you like the G-Shock form-factor and reliability is paramount. It depends on whether you’re looking for the finest possible analysis: multi-band GNSS, mapping, advanced running dynamics — you’ll be better served by high-end running specialists. No if you dream of a “smart” watch with payment, music and apps. That’s another planet.
Curious about the “collection” dimension — because some people like that, and why not? The overview of G-Shocks which are really increasing in value provides useful benchmarks, to be handled with a grain of salt. Usage first, speculation second.
Shopping experience (simple, no traps)
The safest: authorized G-Shock/Casio resellers and official store. Warranty, good cable, clean serial number. Online, demand: mention of the French guarantee, clear photos of the front/back/case, clear deadlines and return policy. And if you are still unsure about the ideal family, choosing between the different G-Shock collections easily avoids buying too big, too heavy, or too complicated for your practice.
Thin wrist, tight budget, want to “feel” G-Shock before moving upmarket? The selection of seven exceptional G-Shocks for less than a hundred euros serves as an honest access ramp. We test, we see if we like it. Then we advise.
Summary – the main points to remember
- Robustness : 20 bar tank, buttons usable with gloves, anti-shock structure.
- Readability : Contrasting MIP + Super Illuminator; nickel full sun and night.
- Sport : GPS/HR/ABCT/VO2max; customizable screens, useful vibration alerts.
- Autonomy : day of effort without cable; daily solar; ~2h35 for full recharge observed.
- Comfort : heavy but stable; try if wrist < 16 cm.
- Boundaries : no map, no apps, optical cardio which sometimes smoothes out the peaks.
- Verdict : for athletes who want hard, readable, simple. Without unnecessary blabbering.
