"Awesome & authentic! I verified it on the Casio website as well. This is my first major purchase from Casio and as a lifelong watch enthusiast it feels special. I've been wanting a Casio watch for over a year and finally found this one at a great price so I didn?t hesitate to grab it. I absolutely love it! The only downside is the negative display ? if that?s not your style I?d recommend choosing the blue or silver option instead."

I really like the clear analogue face and once I downloaded the correct app to set the watch was easily done. Looks real quality and really happy with it. Only slight issue for me is size of digital numerals. More my own eyesight but at certain times analogue hands obscure it. There is a function to move hands from mode area but it’s not easy to remember. But small things. Very happy

Fantastic watch, positive display is a delight, the added lume at 3/6/9 was much needed. Overall I'd say this watch is on par with the GM-B2100 but for less than half the cost due to the resin band!The band is very comfortable, arguably an upgrade, compared to the standard resin GA-B2100 straps.I only have a 6"~ wrist and this newer GBM-2100 strap fits me on the tightest hole (phew!) - whereas I use the 3rd tightest hole on a GA-B2100 strap.The service from firstclasswatches was outstanding as always. I've used these guys lots!!!

I absolutely love this latest iteration of the iconic CasiOak and it is by far my favourite that I own so far. The metal case with ice blue solar dial is just beautiful. Really fast delivery by Francis & Gaye Jewellers who also offered a lower price than most other retailers. Very happy purchase!
I am pretty rough on my watches (not intentionally), so I generally stick with the G-Shock brand watches, simply because they can withstand just about anything you throw at them. But they tend to be a bit on the large and bulky side. With a 44mm bezel (vs the standard 50mm or bigger G-Shocks), the 2100 is much smaller and more practical for regular use, and stylish enough to wear when 'dressing up', while maintaining the same rugged design G-Shock is known for. I also like that there are several varieties of the 2100 to choose from depending on your style and taste (I chose the blackout design because I like the stealthy look of them). But if you are one-the-fence about these watches, I suggest going to the store and seeing them in person! Looking at them online, it ...

Looking at them online, it was difficult to see just how sleek these G-Shocks are, but once I tried them on, I was instantly sold! Definitely not your typical G-Shock. My only issue is the watch band. They seem a little chintzy, but we'll see.
Just purchased this Casio G Shock today and it's fantastic. My local Macys had it in stock like the website said and the transaction was quick and easy. Watch is lightweight, yet rugged as you expect from Casio G Shock. I wore it all day and it felt great. Wears actually smaller than it's dimensions, which is great. The all-black stealth look is really nice. Its only one day, but I expect many years of great service from this Casio just like other Casio's I've owned.
