Cool red watch, that adds a little bling if you want to stand out.
The seller sent me the wrong model watch, the Iron Man G-shock, which I found atrocious looking. But Amazon sorted that quickly and I received the correct item 2 days later. This is a nice watch, I love the looks of the GA-2100 series. This all red edition really pops. The seller's photos are accurate color wise. The digital screen is easier to read than the blackout versions that come with most of this series of watches, but the red background makes the digital info pop when you turn your wrist the right direction in the light, the numbers look blue to me. I had one of the first G-Shocks when they came out in the early 80's. Loved that watch. The strap finally broke, I still have it somewhere. I should probably find it, and get a new battery and strap, I'm betting it would still work. Hoping this one gives me similar service, even if I have to replace the battery more often. I'm planning on buying another version of this watch, so I can interchange components for different looks. I think the red dial would look fantastic in the clear transparent strap/case. or having a black or white dial in the red strap/case would be cool too. As this watch is a lot of red. Only one complaint, and I don't know what Casio was thinking, other than trying to keep this all red, the bands clasp is plastic, instead of metal, like on the other variants of this watch. I see that being a weak point that will eventually break, on a G-shock. It should have been metal, black, silver or anodized red.

A Must Have G-Shock
I’ve been wanting to get this watch since I was a kid and I absolutely love it. It’s stylish and functional. Also I can confirm that it does not come in a metal tin, I got my in a cardboard box.

CasioOak Goodness!
I bought this watch to match a lot of the things I wear for my college alma mater. Frankly, this watch is hard to read due to a lack of contrast... everywhere... on its face. I knew this before I bought it based on reviews and pictures so it meets my expectations. I wear it and like it anyway.

Amazing! Too small? Difficult to read?
It isn't a giant g-shock. That's exactly why I got this: I loved the idea of the g-shock, but I hated the execution. I wanted something tough, but beautiful. This one is light, and I have no problem reading the hour (analog). the digital isn't as clear as the analog part, but I got this specific watch because I love analogs. Though you can indeed see the digital part, it's easier to read the digital part in other models that are only digital. Now, even if this is a "small" g-shock, it's actually a big watch comparing to others I own. I like it very much though, so for small wrist people and for those who just don't want to attach a wall watch to their wrist, it's a great deal.

First off, I didn't think it was possible to find the GA 2100-4A for what retail calls for. I stumbled across Sunsationss selling it for a price that was on par with this, amazing within itself. The watch is as advertised, excellent quality and sleek looks. With all the delays going on, for obvious reasons, they still managed to get the watch to my doorstep 1 day ahead of schedule. Definitely will get my business again, thank you.

Lo compré de regalo para mi primo chiquito y le encantó, creo que es un reloj que no tiene edad y es ideal para todxs También como primeros relojes es bastante bueno para que aprenden a valorar el reloj y a leer la hora

Probably the slimmest, sleekest G-Shock watch. Really vivid color and perfect size Kinda weird to setup but you can easily find in to YT The Red Negative LCD screen is very hard to read without the backlight on tho
