### ⭐⭐⭐⭐⭐ These GA B2100 Watches Are Top Notch
*by M***E on November 24, 2024*

I’ve bought five different versions of the GA B2100 and these are really nice timepieces. The resin bezel & bands are OK, but when you mod them with the stainless steel kits, they tend to really pop. My plan is to modify this model with an SKXMOD mod kit, black bracelet & bezel w/rose gold rivets. I have this tendency to name my modded G-Shocks, this one is going to be my ‘Bumble B2100’. Seriously, these Casio GA B2100 series tough solar, bluetooth watches are very good. Nicely designed. Solar powered so you don’t have the hassle of replacing batteries every couple years. Sets itself with the intuitive and very simple Bluetooth app you simply download to your smart phone. It updates the watch twice daily so the time is always accurate right down to the second. Has all the standard G-Shock features; stopwatch, timer, chime, a very cool reminder feature and phone finder via the bt app. If you misplace your phone, you can locate it quick & easy with this audible function. The watch itself is highly customizable. And with these metal mod kits, you can build a your own unique watch.G-Shock for life! 5*****Stars on all these Casio, G-Shock GA B2100 series timepieces from me. Buy it, mod it, try it and simply enjoy your Casioak.Mr. Lee’s unbiased review.

### ⭐⭐⭐⭐⭐ Time tested!
*by D***T on February 12, 2024*

As long as I can remember, Casio watches have always been top notch quality and very dependable. With great styles and many available options that you may be looking for in a watch, you can't beat a Casio G Shock, although if you wanted to you could because it would continue to work as if nothing happened. A watch that will last a lifetime! ⭐⭐⭐⭐⭐

### ⭐⭐⭐⭐ Great watch, teeny tiny LCD
*by P***E on August 18, 2025*

Well, in wearing it now. I like that you don't NEED an app to get full functionality from it. I like the styling, I like the light, I love solar watches... The only thing I don't love about the watch is that the LCD screen is absolutely microscopic.
