Review: 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 desertcart 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.
Review: Perfect - Good color

## Questions & Answers

**Q: To the human eye, is this a deepish red, tomato or pinkish? Its looks vastly different depending on the video.**
A: This Casio G-Shock GA-2100-4A is a true red. It does not have any pink tones, nor is it dark red.
