Fiery and bold G-SHOCK watches glowing with flames of awesome color. G-SHOCK is all about taking on challenges, and the vivid colorful gradation of the Flame Inside line puts this blazing passion front and center. Beginning with the GA-100 with distinctive large case and the GA-2100 with octagonal case, the design brings in motifs of billowing smoke for the band and features a brightly burning dial in flames of blues or oranges. Choose your favorite look — the GA-100FL-1A or GA-2100FL-1A with vivid blue dial and gradated gray-on-black body, representing the hottest flames of conviction against rising white plumes of smoke; or the GA-100FL-8A or GA-2100FL-8A with bold orange dial and gradated black-on-gray body, evoking flames of fiery passion against a dark smokey backdrop.

Really nice watch to add to my G-Shock collection, the colourway on this model is awesome. Light on the wristfits perfect with the design of the integrated strap. I like the unique design of this new G-Shock i'm thinking of getting the black one for stealth. Thanks Creation Watches!!!

A impressively styled G-Shock that won't break the bank or your wrist.

I really like G-Shock's designs, but they're most often far too large for my liking. I was about to finally pick up the G-2100 "Casioak" this Xmas, but then I saw this new design & immediately forgot the Casioak ever existed. The additional angles on the bezel look a bit like armor plating, but the smaller (for G-Shock) 46mm size still falls along the edge of tasteful watch size standards. And since the strap is integrated into the bezel, the watch wears much better than a 46mm should.As for features, this model has pretty much the same functions as most other G-Shocks: World Time, Stopwatch, Timer, Alarm, Bluetooth, etc., with the only really noticeably missing feature being Solar power. The negative digital display is a bit better than on other models, but still ... MoreI really like G-Shock's designs, but they're most often far too large for my liking.

The negative digital display is a bit better than on other models, but still not quite clear enough to be able to read the time/date/zone/etc. at a glance. And the Light feature, like most G-Shocks, is really just adequate.Other than the small digital display, light function, and lack of Solar, I'd say this is an excellent entry-level G-Shock. It's packed with features, affordably priced, and it'll fit on just about anyone's wrist. I ultimately chose the matte black version, but I think this design will look great in whatever color you choose (or Casio chooses to make over time.)

Good watch and excellent service

As a watch collector I was intrigued with G-SHOCK watches. Purchased this and I am very happy with it so far. It’s comfortable on the wrist and I wear it daily for work. It certainly lives up to expectations. My only criticism is that the writing on the dial is almost microscopic and difficult to read. Great service during purchase and fast delivery. I have a 7 inch wrist and ithe watch looks good.

Good watch.
12 May 2021

I like this watch very much, my first purchase of a new G-Shock, to add to my collection of mechanical watches of mainly Seikos, and an Omega.The set-up is relatively easy; just choose your local time, and city, and enter it. The hands will then move to the correct time, with the same time indicated on the digital display.Because this is a black-out watch, all input for date, etc., is best done in good light, as the display is quite hard to see, being very small, and the small LED light doesn't stay on for long, but is adjustable. I would have liked to have seen the four side buttons a little more bulky, as most G-Shocks are. I found them difficult to push without good finger nails!The watch wears very comfortably.I recommend this watch.

I get the odd G-Shock for eveyrday when I am not going to put my main dress watch on. Also I was born in the 70's so all you millenials reading this... not only did you miss out on the dedaces that influence so much of what you wear today but we were there for the first rounds of the Casio. Were Michael Knight talking into our calculator watches, lost you already I guess ;) Back to google for you then. It has all the looks and feels then tuned up even more of what Casio do so well. The little details but done nicely. You get a hmmm from just looking at it and for under £100 that's job done. I prefer the 'stealth faces' and this one is perfection. My other is a Casio G-Shock 35th Anniversary DW-D5500BB-1 totally nailed it with that design too, so this using hands and ... MoreI get the odd G-Shock for eveyrday when I am not going to put my main dress watch on.

My other is a Casio G-Shock 35th Anniversary DW-D5500BB-1 totally nailed it with that design too, so this using hands and a more upgraded face layout warranted the got to have this now factor kicking in immediately. The strap is slightly shorter than my other one which is proned to catching, but yu can work around that I'm sure. The only thing that's not as tidy with its execution is the backlight. When you engage the light the little digital screen is nice and bright, but the light also doubles up to light up the face of the watch. Well it doesn't. It's not at the rigth height and angle to do that and lights up your bedroom instead. It casts a shadow across the watch face but has not been thought through as to light the face up properly. They fell short with design capability there. The rest of the watch is detail perfect and I have no regrets buying it.
