Make a bold, powerful statement with the Ignite Red line in the iconic black and fiery red that embody the ultimate toughness of the G-SHOCK brand. Casio have injected a few of their flagship models β€” the octagonal GA-B2100 with Bluetooth and solar power; the oversized, solar-powered GAS-100; the GA-100, GA-2200 and GA-700 with signature oversized case β€” with the strength and passion of the black and red G-SHOCK brand colors. Deep, blazing red accents against striking, dark black give these watches, and the wrist that wears them, a kick of cool confidence.

Another perfect Casioak

Bought this in Paris this week. I already have the yellow and this is nice for other seasons, not just summer like the yellow I wear then. Classic G-Shock features, great 'Casioak' design, and the red really contrasts with the black. Tough solar is great and this G-Shock will probably outlive me in 60 years!

I already had a GA2100 with the white indices & hands, then a decided to upgrade to the Bluetooth, solar version. Very pleased with the watch, loving the red & black combos…

I bought this watch because i have been a contented G-Shock watch user for many years. This watch came in a lovely box and is very light on the wrist. I particular liked the colours in this case black and red. The bluetooth and solar powered facilities provide me with an easy to use watch that calibrates itself to my android phone. Very user friendly. Overall a lovely watch I'd recommend and one that would be great in anybodys collection.

Great watch for the summer!
4 May 2023

One of the newer 'Casioak' models. Was delivered promptly.Excellent quality, tough solar powered so no need to worry about batteries. Connected via Bluetooth to my iPhone, makes all the settings really easy to apply and the time is auto synced from the phone.Great fun.

Great watch, poor strap.
11 December 2022

This is a highly practical, easy to maintain (solar + Bluetooth) utility watch. It also looks very smart too, similar to a original Luminox designs. The only feature I would criticise, considering the overall cost, is the strap. The strap is very thin/inexpensive plastic. It doesn't allow the watch to sit as comfortably as it should and it feels quite flimsy, in comparison to the rest of the watch (which is very good). Aside from this GA-B2100BNR is a very nice timepiece. Shame, that for a higher price range G shock, most people (I imagine) will be looking to upgrade the wrist strap to improve the comfort & longevity.

New Watch!
12 November 2022

I primarily bought this watch to replace my old one, whose charging system ( kinetic) was starting to pack up...It's solar charging is very important to me, and so far it's maintaing it's charge perfectly.Set up with the app on my mobile is easy and a great addition, and if I lose it, I can find my mobile by pressing a button on my phone.( Bluetooth has to be enabled on the phone to do this)I'm often in the sea, and if this watch lives up to my old Casio it'll cope fine with that.So, very happy with it so far!

Good value nice looking watch. Bluetooth is a bonus. Would have liked a thicker strap. Well packaged and delivered promptly.

It’s a radical watch that is very versatile for the price. You will have a great time with it. All the features work as expected and it’s just a solid piece of equipment that will last you for years and years. I’m glad I could get it while I could.

Please make more G-shocks for people with smaller wrist
23 December 2022

I love how it's perfect for my small wrist, as G-Shocks are usually bulky. And I hope that if Casio is going to continue to make small G-shocks, please market it to be unisex.And the metallic red sheen on the dials add flare to the already perfect watch.

Stylish GSHOCK
14 December 2022

Excellent everyday watch. Easy to read time. Solar charging, hourly signal and world time feature are very useful for me.I don't have Bluetooth enabled on my phone still the watch keeps accurate time. - no time syncing needed between app n watchWas a bit worried whether the watch would be too bulky for my skinny wrist, but it fits well and looks compact for a gshockcons:The small digital display is a negative display and its sometimes hard to see. The black stealth non Bluetooth version has a more clearer digital display but GA-B2100BNR-1AER has better overall looks.You can set only one timer in the watch.
