Good Slim Casio G Shock Solar Powered Watch
Prefer the slimmer g shocks you can wear under a cuff! This is why I love this one! I chose this one because it was the easiest one to read the hands and I like the colour yellow! It has Bluetooth as well but don’t use it because the other functions on the watch I don’t need to use, I just want to read the time and never need to replace batteries because it’s solar powered! Also mine hasn’t lost a second in a couple of months I have had it! The digital display is very small to see! The backlight very clearly lights up the whole face though! Overall I’m pleased with the watch that it is a very tough, comfortable and light, 200 metre water resistant watch that will last a long time!

Casio hits the spot yet again.👍
G-Shocks are something of a "Marmite" thing in the watch enthusiast community, but like them or loathe them, their place(s) in many collections is(are) justified in my view, so excuse me if this review appears somewhat subjective. That said, if I have moans about an item, they will be listed along with the good points. Onwards... The good bits: This watch is yellow, very yellow! It's also nowhere near as fat as some older G-Shocks and wears very well for a watch whose case size ought to look like a dinner plate on my tiny wrist. Yet it fits every bit as well thanks to the many adjustment holes in its (yellow) two piece strap.The wrist in the attached images has a circumference of a mere 5⅛ inches yet, thanks to the strap heading downwards from the case - a common thing among larger Gs made even more versatile here by the strap's use of quick release spring bars, though a general purpose aftermarket strap would need to be approximately 14mm wide and would lack the visual flow of the factory's stepped strap design, which flares out to match the attachment points on the watch case. Given how much adjustment is available here, even a thick wristed man could find this just as comfortable as I, a skinny wristed woman, do. The buckle appears at first glance to be the plastic type found on some more budget oriented Casios, but no, it is made from a nicely finished - no sharp edges here - piece of stainless steel. Then we come to what it does: This watch has the Bluetooth facility so that the time can be synchronised with your smartphone, tablet, etc. I find this to be more useful for making settings adjustments as the paired device will have a much larger display than the G's digital area, bottom right of the dial. I deliberately avoided letting the watch connect to my phone for two weeks after the initial pairing and setup. Unsurprisingly, the watch remained accurate as most of the range will when left to their own regulation of the time displayed. OK, so I admit that I like most G-Shocks though for me, the resin case is a large part of the appeal and a factor in the brand's legendary resistance to damage, but if the buyer were thinking of modifying their G's appearance by fitting one of the many "upgrade" kits available these days, I would tread carefully and perhaps read my review of how such a mod went when I bought a kit. Best advice; if you must have some metal attached to a light watch whose feel and balance on wrist is a result of its synthetic construction materials, buy one of the Gs that come from the factory with metal cases and straps. Those won't give you a nasty rash, are made beautifully and tend not to feel top heavy. I get the appeal of modifying a watch, but was glad to refit the original plastics to my GA-B2100 after my own less than worthwhile decision to mod the watch. All that experience taught me is that the G-Shock is just right as its maker provided and if I feel the need for a heavy metal experience again, I shall satisfy this urge by listening to a classic AC-DC album at full volume. So what's not so good about the GA-B2100? Sorry folks, but I did say at the start that I may become subjective and OK, so some of us will spend ages looking for some glitch or other, but there really isn't anything that disappoints me about this watch. Sorry there's nothing to report, but buying a watch from the 2100 range is very unlikely to be something you'd regret. I chose the solar one with Bluetooth, and it was on offer at the time, but even at around the typical maximum £160 or so, I would have been just as happy with my purchase. End.😁 🌟🌟🌟🌟🌟

Beautiful, Tough and Functional
This watch is just lovely. Wearing such a powerfully yellow watch on a warm summer's day is a joy. The connection to your Bluetooth ensures perfect time keeping and I use the time on this watch to help keep my other watches accurate. I have a 6.5 inch (16.5cm) circumference wrist and the watch does not look too big. It even looks really good on my wife's much slimmer wrist. Solar powered too! And the display is so clear. Highly recommended

Great watch and great value
Love this watch. For what you get it's fantastic value. The solar power means very long battery life and the bluetooth connection to the phone means ultra accuracy. I love the colours. If I had any complaint it would be the resin case/strap is quite plasticky. I knew this before purchasing but didn't realise quite how stiff and creaky it would be. It actually squeaks and creaks when you flex your wrist. I've read online this goes away with wear. Ultimately, the value of the watch completely destroys any negatives like the quality of the resin for me. One point, with it being such a bright colour it looks BIG on the wrist. I've got a dark green model of the casioak so same size, etc and it visibly looks smaller on the wrist so just be aware of that if you're thinking of buying the yellow model.

The Perfect Blend of Retro Style and Modern Tech
I honestly couldn't be happier with this purchase. I’ve always liked the look of the octagonal "CasiOak" G-Shocks, but this yellow GA-B2100 version just hits differently. It’s got that perfect pop of color that stands out without looking like a toy. The best part for me isn't even the looks—it’s the convenience. It’s got Tough Solar, so I never have to worry about the battery dying, and the Bluetooth sync is a lifesaver. Setting the time on a G-Shock used to be a bit of a headache with all the button-pressing, but now I just link it to my phone and it’s done in seconds. Even though it’s a G-Shock and can take a beating, it’s surprisingly slim and lightweight on the wrist. It doesn't feel bulky under a sleeve, which was a huge plus for me. If you’re looking for a watch that’s basically indestructible but actually looks stylish enough for daily wear, you really can't go wrong with this one.

Bright summer watch
Arrived on time in perfect condition, standout watch for summer, gets lots of attention well you can’t miss it in the bright yellow, my son likes Pokémon so it’s now a Casio pikachu, it’s my second Casio and I’m already eyeing up a third one.

Didn't work at all
I was a bit worried when I first saw the box was a bit tatty. It looked as if it had been in storage quite a while so I guessed that the battery would be completely discharged. Indeed, the indicator showed it was completely dead. There was no reaction from the watch at all. After several hours in bright sunshine the indicator hadn't moved . The watch was still totally unresponsive. Had to return it.
