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 Amazon (not a third part 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.

Accurate, reliable and built to last
If you want a simple and accurate digital watch that will last for a long time, I can think of no better watch than this watch. Growing up I wore many Casio digital watches and they all took a tough beating and kept on working. None of those were even a G-Shock watch. The biggest issue I had years ago with Casio watches was that the plastic band would eventually get a bit brittle and break after several years of wear. This watch has a stainless steel band that should hold up for years and years. The stainless steel bands are also more comfortable on the wrist and won’t create hot spots on the wrist like plastic watch bands can, especially if the band is thicker or stiff.It is a bit tricky to size the watch band. Most of the links don’t have holes on the sides of the links to use a standard watch band tool to remove the links. It gives for a cleaner looking design, but it makes it a bit hard to resize, especially if you’re not use to these types of watch band links. I was able to use a very small flathead screwdriver to remove the pins. There’s a notch on the inside of the band that allows you to get to the pins. Attaching the links back seemed like the harder part at first, but it seemed easier towards the end when I held the pins from the outside portion of the band instead of the inside portion with the notch. The pins started clicking in easier.The watch lights up using an indiglo backlight similar to how many Timex watches light up. It doesn’t get very bright. The worst part about the night illumination is that it only lasts about 2-3 seconds or barely long enough to read the time. You might want to light the watch up 2-3 times to read the time in complete darkness. I’m sure they were trying to save battery life, but they should extend the time it stays lit to 5-6 seconds.The watch came fully charged for me, unlike for some. The time has been perfectly accurate in comparison to the time on my phone, computer and cable tv box. With the syncing to the atomic clock, this watch should always be very accurate. And unlike those Casio watches that I had growing up, with this watch being solar powered, I shouldn’t have to worry about the battery for a long long time. The old Casio watches the original battery would last about 5 years and any replacement batteries would last about 2-3 years.The watch seems very comfortable. The watch is a bit thick due to the G-Shock protection, but it’s not very noticeable.If you like watches with big watch faces, this watch probably isn’t for you. It has more of what I’d call a standard size watch face. The characters are plenty large enough to read though.It looks like it has some stopwatch capabilities, but other than that it just keeps accurate time.If you want a simple, comfortable, accurate, long-lasting watch that can take a beating… this is that kind of wristwatch.

One bad point. This model doesn't appear to have ever been released in the UK so Amazon US was the only option. For some reason budget Gshocks in the US come in flimsy cardboard boxes and it was shipped in a plastic bag for the 4000 mile trip. Unsurprisingly it arrived a bit battered but better than others I've had. Fortunately it's a gshock so can withstand abuse but I would be hesitant to order a conventional watch from the US.
Overall this is a great digital watch that comes highly recommended. I'm not sure how much longer these will be produced so grab one while you can.

MAGNIFIQUE MONTRE CASIO SOLAR

Je précise car cela a son importance vu qu'il on était réellement parfait.
Pendant mon achat le prix a baissé passant de 160€ a 114.9€ de quoi etre bien déçu, ce vendeur plus haut sité a fait remboursement des sommes de differences.
Je lui ai indiqué que la montre devait etre bien mise dans ma boite a lettre et pas déposé dehors... Tout a été fait de maniere irréprochable ! Parfait.
Concernant la montre, j'ai une g shock solaire elle est toujours en parfait etat et fonction tres bien malgres le poids des ans quel robustesse les casio c'est dingue.
Cela dit j'ai regretté d'avoir un model certe qui me plait mais avec un full resine qui manque de premium a mon goût... Surtout que la montre ne meurera jamais donc envie de me faire plaisir avec une casio solaire a nouveau mais plus premium... Pas dans les fonctions inutil compas. Altimètre... Etc.. Juste une montre a la sauce casio... Numerique avec alarmes eclairage auto, radio pilote, compte a rebours 1h, chrono 1/100eme, bip a chaque heure qui est indispensable pour moi.
Le poids ce fait sentir, on a une impression steel tres evidente, la tenue reclame un reglage du bracelet et après ca on l'oublirait presque.. Nul besoin d'un poigné de culturiste pour porter avec élégance cette magnique montre, elle est de la famille g shock mais respectueuse des proportions standard.
Cette montre est un vrai bijou, deja observé dans des longévité superieur a 20ans et aucun même apres tous ce temps n'a idee du temps restant avant qu'elle rende l'ame, je pense que ce sera ma derniere montre, et j'en suis ravi.
les goûts et les couleurs c'est chacun son truc, donc je parle évidemment que pour moi... La qualité et la beauté de cette montre valait que je la paies 160€ et le hazard me la fait avoir a 114€...
Un must de la marque casio a ne pas manquer, elle est superbe et je la recommande même a bien plus cher que 160€ car bien plus cher ailleur!
Sinon le dit vendeur est parfait.
