  • G-Shock Ga-2100
This is an excellent G-Shock! Comfortable to wear and stylish to look at. I wanted a non digital display g-shock and this fitted the bill for looks and price. It is easy to read - unlike some of the other faces where you cannot see the hands. Also the light is good for nighttime. Overall this is an excellent G-Shock and good value for money. ... show more

  • Awesome watch. Can’t go wrong.
The media could not be loaded. It’s just an amazing watch. Yes it is a popular model but for a reason!! It’s a perfect one for all kind of watch, you can dress up or down with it easily. Especially this color scheme with the white hour markers it is just stunning, not to even mention how comfortable it is, how accurate it is, how reliable it is. Overall you CANNOT go wrong with this model. The price of 90 dollars is definitely justified. ... show more

  • This is the famous “Casioak”
So named for its resemblance, due to its octagonal bezel, to the Audemars Piguet Royal Oak, an all-metal luxury sports watch that was introduced in the early 70’s. Fortunately, the Casio doesn’t resemble the AP in terms of price!! The G Shock is made mostly of resin, some of which is reinforced with carbon fiber. This model comes in several colors, and the version I bought, black with white hands and hour markers, is one of the most legible, in my opinion. It’s a very light, comfortable watch to wear and looks great. I don’t have a problem with the negative digital displays, because the backlight illuminates them well. Just one minor complaint—they are a bit small. Other than that, a good job by G Shock. ... show more

  • Really great timekeeper, with some cons.
I was looking for a simple watch that was easy to read, simple to use, and durable (I didn’t want any Bluetooth or phone connectivity). This is a great watch and if I had the choice I would buy it again. I love the look of it with the grey markers and negative digital display. The pros: - simple to use - easy to read in most lighting conditions - great backlight - looks great - has quick release watch straps so the band can be changed fairly easily - good price/value for money - not as bulky as many other GShock watches The Cons: - the mineral glass scratches way too easy. This is my biggest gripe so I have to expound on this a bit. I’ve owned this watch a little over a week and haven’t done anything out of the ordinary while wearing it or storing it. After washing my car I noticed a scratch in the glass that goes nearly across the whole glass (you can see the scratch in one or more of the photos). No idea where the scratch came from, I’m really surprised that the mineral glass is this soft. - the band it comes with is not the most comfortable As is, I would still buy this watch again or recommend it to a friend. Just be aware before buying: consider a screen protector if you don’t like a scratched watch glass. ... show more

  • Slimmer than the normal G Shock - seems just a durable
I like the slimmer profile. Particularly useful when i was working on the wife’s car last weekend. The face is easy to read and at last it has luminous hands and light is good and it illuminates the whole face and the digital window. It’s very light and comfortable. The dislikes, minor, the digital screen is small but better contrast than other models, but it is small. In bright light it is easy to see. In less well lit areas hit the light and it is manageable for my 59 year ago eyes. I am a G SHOCK fan and own many different versions, this is one of the better ones in my opinion. ... show more

  • Fantastic watch
I agree with the visibility reviews: the digital screen is hard to read. But honestly, I think the understatement is the point. The watch is super comfortable and super good looking. Love it!! Definitely get a screen protector for it as it doesn’t have sapphire glass (cmon, Casio!)
