Casio

With 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.

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.

5.0 out of 5 stars Excellent old school G-Shock
Reviewed in the United Kingdom on February 18, 2024
I had my eye on this one after I regrettably sold my similarly designed G510 last year. I owned that watch for nearly 20 years and it never missed a beat. Apparently this MTG has also been in production for 20 years but had a refresh with a newer module about 7 years ago. It's a fairly chunky watch at 46mm across and 16mm thick but these stainless steel bracelet versions wear small and are so comfortable on wrist. Some great features with multiband 6 and tough solar plus a clean display with large numbers and the usual stopwatch, timer alarms etc. The links between the case and bracelet look a bit mismatched in photos but are okay in the flesh. Most people like the squares but for me this is much better watch with the same features as a gw5610 and cheaper as well.

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.

Acheté et livraison par VirVenture... Sur ce site.
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.
