Review: Based on owning one for over a year. In short: this watch is exceptional. If you’re into rugged, feature‑packed tool watches, it really delivers. But like any high‑end tough watch, it has trade‑offs. I’ll cover everything—what I love, what could be better, and whether it’s worth the price. What Makes It Amazing (What I Love) After a year of daily wear, especially outdoors, travel, and “real‑work” use, these are the highlights: Durability This thing really lives up to its rugged billing. Mud, rain, grit, dirt, occasional bumps—all no problem. The “Mud Resistance / Mudmaster” name is not just hype. The button guards, sealings, materials hold up. Even after rough use there’s minimal cosmetic wear (very, very light scratches here and there) and zero functional issues. Reliability / Power Solar charging works well. Even with mixed conditions (indoors some days, outdoors others), the battery remains in healthy levels. Also the Multi‑Band 6 atomic time sync keeps time dead‑on without needing constant manual adjustment. For a guy who travels or changes timezone occasionally, that’s a huge relief. Sensor Suite & Utility * Altimeter/barometer: I use these often when hiking. The trends are useful (pressure rises/falls). * Compass: very handy when navigating off‑road. The bearing memory and location indicator functions (via the app) add extra value (set a point, coming back to it etc.). * Thermometer: works decently well (though you need to remove watch, let it settle to ambient) but adequate. * Sunrise/sunset: surprisingly useful. I don’t need to pull out my phone constantly to check light conditions. Visibility & Readability The sapphire crystal is excellent—no hazing or major scratches. The anti‑reflective coating helps a lot in bright sun. The analog hands are large enough, clear; the Neobrite luminescence (glow) is decent, enough to read things after dark. The dials and subdials are intuitive (once you’ve gotten used to where everything is). Build & Style / Presence Let’s face it: this watch *looks* and *feels* like a flagship. It has weight, heft, and that “pro tool” aesthetic. The metal + resin + carbon/bio‑resin combination gives it both toughness and a refined edge. On‑wrist it commands attention without being gaudy. Added Modern Conveniences Bluetooth + app connectivity, location‑indicator functions, auto correction of altitude, ability to adjust settings via phone—these make using it much more convenient than purely analog/digital watches without these features. Things That Could Be Better (Trade‑Offs / Minor Drawbacks) Even though the watch is amazing, there *are* trade‑offs and “wish’d it were slightly more perfect” bits (just to give a balanced view): Size & Bulk It is large and thick. The 16‑mm thickness plus wide band make it feel chunky. On smaller wrists (or under tight shirt cuffs) it can be a bit intrusive. For everyday formal wear, it might be overkill. Complexity / Learning Curve There are a lot of modes, subdials, buttons. If you don’t read the manual (or use the app) to understand what each sensor, dial, subdial, or function is doing, it can be a bit confusing. Adjusting, calibrating sensors (esp compass/altimeter), knowing how to use bearing memory etc. requires some patience. Response Time / Sensor Precision Some sensors (like temperature) lag behind environment unless you let the watch stabilize. The compass occasionally requires recalibration in various magnetic environments. The altitude readings are accurate but not perfect—especially in changing weather conditions or when moving quickly. That’s expected, though, given the tech. Weight vs Comfort While 114g is lighter than some comparable tool watches, it’s still noticeable. After several hours of wear (especially doing strenuous things or arm movements) you feel that weight. The band is rugged but not super plush; for extended wear (e.g., all‑day hike), pairing with lighter straps (if possible) helps. Price This is a premium model, and the price reflects that. For those who need only basic functionality (such as time and stopwatch), there are more affordable G-Shocks that deliver excellent value. If you’re buying this, you’re paying partly for ruggedness, materials, prestige, and features. That’s fine if you use those; less so if many features will go unused. Limited “Smartwatch” features It’s not a smartwatch. No notifications, limited to noizable phone alerts, no fitness tracking (steps, heart rate etc.). If you expect those in a “connected” watch, you’ll be disappointed. It’s more tool‑watch + sensor + time keeping + ruggedness, rather than “smartwatch replacement.” My Experience Over 12+ Months Putting together how it’s held up and how I actually use it: * I’ve used it in rain, mud, sand. After sweaty sweaty days in hot sun & humid weather, it still functions beautifully. No issues with fogging or moisture infiltration. * Solar holds up nicely—even in seasons or locations where sun is sparse, the power reserve stays healthy. * The Bluetooth + app still functions well: occasionally a firmware downward tweak, but generally stable. Calibrating sensors via the app has been easier than fiddling with buttons. * The watch feels like it could survive decades of rugged use. The case, crystal, bezel guards still look solid. Some light paint wear/finish wear on button edges, but given how much punishment it’s seen, that’s totally acceptable. * I tend to wear it more than dress watches now, even in urban / work settings, because it gives me peace of mind: “I don’t need to baby this one.” Should You Get One? Who It’s Best For Given everything, I think this watch is worth it, if you fall into one or more of these categories: * You spend a lot of time outdoors (hiking, camping, fishing, construction, fieldwork etc.), and need a rugged, reliable watch with robust sensors. * You appreciate tool‑watches more than fashion watches. Function over frivolity. * You want features like solar charging + radio time sync + compass/altimeter/barometer built in, so that you’re not pulling out multiple devices. * You don’t mind size / bulk; you want toughness and don’t care much about a thin profile. Final Thoughts After over a year, the Casio G‑Shock GWG‑B1000‑1AJF isn’t just good—it’s impressive in nearly every respect it sets out to deliver. The build, durability, sensors, power, and utility justify the cost for those who actually need them. It’s not perfect, but its imperfections are small compared to the strengths. This is a beast of a watch that works as hard as you do, and will keep up through nearly anything you throw at it, and will likely continue to work and survive after a Zombie Apocalypse.
Review: Awesome watch… Actually comes from Japan with an instruction book only in Japanese to prove it 😂. Seriously, this is a great solar watch. I work indoors most of the day and the battery is full every time I check it. Very rugged, very stylish for a watch of this type. I get a lot of comments/compliments about it. Buttons on the sides of the watch are protected but large enough to be easy to use. The light 💡 it extremely bright at night.. I have had many Gshock’s over the years but this is the best by far and although it is not cheap I believe that it will last a very long time…

フロッグマンから乗り換えです。 フロッグマンよりだいぶ短いベルトで、短めです。 手首が太い人にはきついかもしれません。
