This "CasiOak" has quickly become one of my favorite watches! I really like the white dial with the grey band. The negative display looks amazing contrasting with the white dial.The band feels great on this lightweight watch. It wears quite well and feels very comfortable on wrist. When you hit the watchface with an led flashlight (or take it outdoors in the sun) the entire watchface glows quite well. It glows bright for about 10-15 minutes before it gradually fades.I am very happy with this watch and would highly recommend it to any G-Shock fan!

Nothing really wrong with this watch. I had to watch a YouTube video to get it set properly because it's overly complicated and the manual was not the most well versed in explaining the process. The gray color isn't striking and has a cheap look to it. It caught my eye in the pics but didn't satisfy as I'd hoped. Considering returning it. I read so many hyped up reviews of G Shocks saying they're the best dive watches for the money but they don't seem like anything more than a $30 Casio to me. At least based on this one

The best gshock series. Looks great, durable watch for all season.

I wanted a better looking beater watch. it looks great during the day, but the glow in the dark dial is what it is. It's a cool thought.I would recommend it if you are okay with the luminous dial being just a novelty.

Got this watch for the glow, it does good this way. If you charge it with a flashlight it will hold a lot of glow for some time. Very nice design. Easy to set up for time, no Bluetooth for the Casio app.

Wow.This watch is stunning. Currently, the only other Casio I have in my collection is the GWM5610U. I enjoy the retro look with modern features all integrated into a nice resin square design. I have heard great things about the “Casioak” variant G-Shock but never pulled the trigger on one.After just recently purchasing this model of Casioak, I couldn’t be more pleased. It looks MUCH better in person than I could’ve imagined. The white dial is more of an off-white color with a unique shade when the “Lume” kicks in.The design itself feels sleek, casual, yet robust all at the same time. The color palette they used for the bio-design strap was a great pick in my opinion. It contrasts well with the indices on the off-white dial itself. In the darker environments it looks like it’s a black watch with a really bright face on it. With multiple personalities to it- this thing really is kick ass.With that being said, I do not agree with the negative display it has. I think a much more vibrant contrast of white with black text would’ve been the better move. It does have a nice contrast color to it though, so it’s quite hard to really even call it a major gripe.It would’ve also sealed the deal as my favorite watch in my collection if it was Bluetooth and solar powered. I just wish they didn’t advertise that directly on the dial either.TLDR; If you’re on the fence about buying a GA2100 Casioak, just buy it. It’s relatively cheap for the absolutely amazing product you’re buying. Highly recommend it in any price range collection you have. They end up hitting high above their weight class with this GA2100, and I can guarantee that it looks good with almost any outfit.
