CasioWith the launch of its first watch in November 1974, Casio entered the wristwatch market at a time when the watch industry had just discovered digital technology. As a company with cutting-edge electronic technology developed for pocket calculators, Casio entered this field confident that it could develop timepieces that would lead the market.Today, Casio is focusing its efforts on solar-powered radio-controlled watches: the built-in solar battery eliminates the nuisance of replacing batteries, atomic timekeeping means the users never have to reset the time. Recently, Casio launched a series of Bluetooth watches that sync to the users cell phone to automatically update the time. Casio is always moving time forward.

Review: Nice bang for the buck. - Casio’s G-Shock is noted for toughness and durability, and the MT-G line is something more. The MT stands for “metal twisted” - the entire line has a unique feature I’ve never seen elsewhere. Much of the metal used on the case of a G-Shock MT-G watch is just an outer shell, filled inside with the same hard resin used to make cases in most other G-Shock watches. You get the strength and appearance of a classy, metal watch, but the lighter weight of a plastic resin watch. When you pick this watch up, it weighs much less than you expect it to, but it’s still a G-Shock and every bit as durable. In addition to the usual features found in most modern G-Shock watches (world time for 48 cities, alarms, countdown timer, stopwatch, 12/24 hour time display, DST function), this watch has two more, less-common features: Tough Solar and Multi-Band 6. Tough Solar means that the watch uses solar cells in the face to recharge a capacitor - no more replacing batteries. With my Tough Solar watches, I find that an hour or two of bright, direct sunlight a month is enough to keep the capacitor at high charge (the display has a power reserve indicator on the top left). When you don’t wear the watch for a while, darkness will trigger power save mode, shutting down most of the display to extend the battery charge duration; only the power save indicator stays on. You can press a button or expose the watch to light to wake it from power save mode. (You can disable power save mode in the settings, but this is only recommended if you wear it frequently and it gets some direct sunlight now and then - such as if it’s the only watch you wear and you spend some time outdoors regularly, or you often leave it on a bright window sill.) With power save on at full charge, the watch will go for nine months before the capacitor is drained - never let a capacitor get to zero charge; it will likely need to be replaced. Multi-Band 6 means that when you’re in most of North America, Europe and Asia, your watch will use a built-in receiver to pick up a time sync signal from one of six radio stations worldwide that are linked to atomic clocks - this happens daily, is automatic (it usually tries in the early morning hours when most people are sleeping), and means that your watch is as accurate as you can get without spending a fortune. Radio signals from these stations can be difficult to receive under certain conditions - such as inside a steel-and-concrete building away from windows that face the right direction, or on the side of a large hill or mountain that faces away from the station. In these cases, you can manually trigger a time sync when you are in conditions more conducive to longwave radio reception. If that fails, you still have the option to manually adjust the time as needed. (For reference, the US signal is from an NIST facility broadcasting just outside of Fort Collins, Colorado, so for most people in the US, anything obstructing radio signals north and/or west may prevent a time sync; the closer to the signal you live, the stronger it should be.) I left out the best for last. This watch is the absolute least expensive MT-G model on the market today. Granted, it isn’t as fancy or classy-looking as the other MT-G watches, but most of them start at $950 (for a model with a titanium case and resin bands) and go up to as high as $1450 at the time I’m writing this. Many models are limited editions and frequently sell out fast. This is because most of the MT-G line, with the exception of this watch, are completely analog but have most of the same, exact functions as this watch - they’re considered high-end, fashionable collectibles. They’re also hand-crafted in Japan; this one isn’t. (Most Casios are made in either China or the Philippines.) Even if you “step down” to a “Full Metal” G-Shock (all-steel case and bracelet), they typically run between $500-$600, and the G-Steel line (steel cases, resin or rubber straps) are a few hundred dollars - even on sale, they cost more than this one! At the time I’m writing this, Casio sells this model direct to consumers for $170, and desertcart (not a third party seller) sells it here for some pennies under $100. If this was too long, here’s the summary: you get an excellent feature set for a bargain price with all the toughness of a G-Shock, and a look that wouldn’t be out of place with a suit and tie. Never needs a battery, always has the right time within a second or so.
Review: Very impressive watch for the sale price! Older style, but sturdy and reliable. - Bought this on sale at just under $100, and, wow what a great watch for the price. It's an older style (originally a 2012 release), mostly metal, but it is by far the least expensive MT-G labeled Casio out there. The MT-G line is a big step up from the regular G Shocks. And, most of the new MT-G watches go for $1,000+ new. This watch has almost the same features- solar charging, multi-band radio time synching, 200M water resistance, and the stopwatch, timer, world time, and the rest. It does not have bluetooth, which seems to be the most recently added feature. Otherwise, it has the bells and whistles. It is made in Thailand and not in Japan. But, if you like the look, it's a real bargain. I've been wearing Casio solar, radio synching watches for years now and they are well made and last. The metal band requires adjustment, which can be daunting if you are not familiar with how these link-type bands work. I found it w=easier than some Seiko bands to adjust. BUt, it does take a little time and knowledge. So I would suggest watching a video if you've never done it before. It took me about 15 minutes to remove the links needed and to fit the watch to my wrist. It is really quite comfortable, once properly fitted, but much heavier due to all the metal, than a standard resin Casio. My watch came in a rather plain and crushed G Shock cardboard box, but it was all there. So there wasn't any upscale packaging. Perhaps the box had been opened before, but the watch is fine and all the paperwork was there. If you like the style, go for it- you won't find a better watch for under $100.

## Questions & Answers

**Q: How loud is the alarm?  can i rely on it to wake up every day like i do with my timex ironman?**
A: no it is pretty soft and only audible if u are a light sleeper

**Q: Ok so watch is waterproof, but how will stainless steel band hold up to 1hr/day of lap swimming or taking my son swimming a few hrs per pool visit?**
A: Band is durable (no rust = nothing visible)

(Weak points)

plastic pieces (6 & 12 that connects to band = brown/tan/gray pieces) dry rot 1.5+ years of 24/7 use (sun, sweat...)

Screws & pins (attachment points for band & links = will corrode, stiffen up... Only noticable when swapping bands/links)

**Q: By chance, is there a comparable "non-metal" wrist band that works with this watch?**
A: You might try the CASIO BLACK RESIN-OC-500-1A the band with at the watch head is 24 mm and the band that comes with the watch is 23 mm.  I think it should fit.

**Q: can you shower with this watch? also is there any special way to clean this?**
A: I have been to war with this watch.  In fact, I have owned this watch for more than 10 years.  I have rarely taken it off at all.  Will it survive a shower you ask.  It has survived hours in the ocean, rivers, creeks pools, hot tubs, you name it.  It is a beast.  One full charge from exposure to the sun and you can go dark for 9 months without sunlight.  It is hands down the best watch I have owned.  The only visible difference between day now to day then is the black lettering is no longer black, it is now just the same color as the engraved stainless steel.  The steel band feels like quality and it looks great.

### ⭐⭐⭐⭐⭐ Awesome watch
*by I***R on January 5, 2025*

Bought almost this same exact model (MTG-900) over 14 years ago in Hawaii when my previous G-Shock with the black plastic/rubber watch band was lost to the Pacific ocean. I have to be wearing a watch. Have since I was a 10 or 12 year old. So I went to Costco to see what they had and that was the closest I could get to what I had. Was not happy about the stainless band. Had never had a metal band before but it was only $70 and was a G-Shock. Would probably never go back to any other band. Slip it on and close the clasp and ready to go. It has never worn out/broken like the black plastic ones do. The watch itself is awesome. The only reason I bought this as a replacment was that the luminescent back light was not staying on when the button was pushed. It would blink on and off really quickly. Thought maybe it was dying and then got the idea to replace the battery, which I had never had to do up to that point. After all, it is solar powered. Anyways, all it was was a dead battery (which is a rechargable CTL1616 watch battery). The solar power is what recharges/keeps it charged. After 14 years it could no longer keep a charge or fully charge (there is a little 3 segment display on the watch indicating level of charge which I had never even noticed or payed attention to). Replaced the battery and did a lot of cleaning of all the rubber and chrome pieces and it is almost like new. Now I have a spare watch for when this thing actually does die permanently. I have never had to worry about keeping it charged or anything like that (never even noticed that there was a gauge), although I have always worn short sleeve shirts and I am in the Sonoran desert after all, which probably helps. Love the atomic time keeping function which works great in my locale. Place the watch on the window sill each night and I have 100% accurate time all the time. The LCD is highly visible at all angles unlike some watches that have matrixed LCD displays. 14 years and barely any visible scratches on the crystal. Has all the features I need. Some reviews complained that the LCD characters are too small but I am 61 years old and use reading glasses and I can see the characters without those so they are big enough for me. This will probably be the watch I will be wearing when I die and there is a good chance I'll never need this spare. The fact that they are making this exact same watch (essentially) for at least more than 14 years tells you all you need to know.
